Uses For hydrocortisone valerate


Hydrocortisone valerate topical is used to help relieve redness, itching, swelling, or other discomfort caused by skin conditions. hydrocortisone valerate is a corticosteroid (cortisone-like medicine or steroid).


hydrocortisone valerate is available only with your doctor's prescription.


Before Using hydrocortisone valerate


In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For hydrocortisone valerate, the following should be considered:


Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to hydrocortisone valerate or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Pediatric


Appropriate studies have not been performed on the relationship of age to the effects of hydrocortisone valerate topical in the pediatric population. However, because of hydrocortisone valerate's toxicity, it should be used with caution. Children and teenagers who must use hydrocortisone valerate should be checked often by their doctor since hydrocortisone valerate topical may be absorbed through the skin and can affect growth or cause other unwanted effects. Safety and effectiveness have not been established.


Geriatric


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of hydrocortisone valerate topical in the elderly.


Interactions with Medicines


Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.


Interactions with Food/Tobacco/Alcohol


Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.


Other Medical Problems


The presence of other medical problems may affect the use of hydrocortisone valerate. Make sure you tell your doctor if you have any other medical problems, especially:


  • Cushing's syndrome (adrenal gland disorder) or

  • Diabetes or

  • Hyperglycemia (high blood sugar) or

  • Intracranial hypertension (increased pressure in the head)—Use with caution. May make these conditions worse.

  • Infection at or near the place of application or

  • Large sores, broken skin, or severe injury at the area of application—The chance of side effects may be increased.

Proper Use of hydrocortisone valerate


Use hydrocortisone valerate exactly as directed by your doctor. Do not use it for any other condition without first checking with your doctor. hydrocortisone valerate may cause unwanted effects if it is used too much, because more of it is absorbed into the body through the skin.


Wash your hands with soap and water before and after using hydrocortisone valerate.


Be very careful not to get hydrocortisone valerate in your eyes. Wash your hands after using your finger to apply the medicine. If you accidentally get hydrocortisone valerate in your eyes, flush them with water.


Apply a thin layer of hydrocortisone valerate to the affected area of the skin. Rub it in gently.


Unless otherwise directed by your doctor, do not apply hydrocortisone valerate to open wounds, burns, or broken or inflamed skin.


hydrocortisone valerate should only be used for problems being treated by your doctor. Check with your doctor before using it for other problems, especially if you think that an infection may be present. hydrocortisone valerate should not be used to treat certain kinds of skin infections or serious problems, such as severe burns.


Do not bandage or otherwise wrap the skin being treated unless directed to do so by your doctor.


If your doctor has ordered an occlusive dressing (airtight covering, such as kitchen plastic wrap or a special patch) to be applied over hydrocortisone valerate, make sure you know how to apply it. Since occlusive dressings increase the amount of medicine absorbed through your skin and the possibility of side effects, use them only as directed. If you have any questions about this, check with your doctor.


Do not use hydrocortisone valerate on the face, groin, or underarms unless directed to do so by your doctor.


Dosing


The dose of hydrocortisone valerate will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of hydrocortisone valerate. If your dose is different, do not change it unless your doctor tells you to do so.


The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.


  • For topical dosage forms (cream and ointment):
    • For redness, itching, and swelling of the skin:
      • Adults—Apply to the affected area of the skin two or three times a day.

      • Children—Use and dose must be determined by your doctor.



Missed Dose


If you miss a dose of hydrocortisone valerate, apply it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule.


Storage


Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.


Keep out of the reach of children.


Do not keep outdated medicine or medicine no longer needed.


Ask your healthcare professional how you should dispose of any medicine you do not use.


Precautions While Using hydrocortisone valerate


It is very important that your doctor check your or your child's progress at regular visits for any problems or unwanted effects that may be caused by hydrocortisone valerate.


If your symptoms do not improve within 2 weeks, or if it become worse, check with your doctor.


After applying hydrocortisone valerate to the skin of your child, watch the child carefully to make sure that he or she does not get any of the medicine in the eyes or mouth. hydrocortisone valerate can cause serious side effects, especially in children, if it gets into the mouth and is swallowed.


Using too much of hydrocortisone valerate or using it for a long time may increase your risk of having adrenal gland problems. The risk is greater for children and for patients who use large amounts for a long time. Talk to your doctor if you or your child have more than one of these symptoms while you are using hydrocortisone valerate: blurred vision; dizziness or fainting; fast, irregular, or pounding heartbeat; increased thirst or urination; irritability; or unusual tiredness or weakness.


Stop using hydrocortisone valerate and check with your doctor right away if you or your child have a skin rash, burning, stinging, swelling, or irritation on the skin.


Avoid using tight-fitting diapers or plastic pants on a child if hydrocortisone valerate is being used on the child's diaper area. Plastic pants and tight-fitting diapers may increase the chance of absorption of the medicine through the skin and the chance of side effects.


Do not use cosmetics or other skin care products on the treated skin areas.


hydrocortisone valerate Side Effects


Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

What is Trivora-28 (ethinyl estradiol and levonorgestrel)?

Ethinyl estradiol and levonorgestrel contains a combination of female hormones that prevent ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.


Ethinyl estradiol and levonorgestrel are used as contraception to prevent pregnancy.


Ethinyl estradiol and levonorgestrel may also be used for other purposes not listed in this medication guide.


What is the most important information I should know about Trivora-28 (ethinyl estradiol and levonorgestrel)?


Do not use ethinyl estradiol and levonorgestrel if you are pregnant or if you recently had a baby. Do not use this medication if you have a history of stroke or blood clot, circulation problems (especially if caused by diabetes), a hormone-related cancer such as breast or uterine cancer, abnormal vaginal bleeding, liver disease or liver cancer, severe high blood pressure, migraine headaches, a heart valve disorder, or a history of jaundice caused by birth control pills. Taking hormones can increase your risk of blood clots, stroke, or heart attack, especially if you smoke and are older than 35.

What should I discuss with my healthcare provider before taking Trivora-28 (ethinyl estradiol and levonorgestrel)?


This medication can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control pills (6 weeks if you are breast-feeding). Do not use this medication if you have:

  • a history of a stroke or blood clot;




  • circulation problems (especially if caused by diabetes);




  • a hormone-related cancer such as breast or uterine cancer;




  • abnormal vaginal bleeding;




  • liver disease or liver cancer;




  • severe high blood pressure;




  • severe migraine headaches;




  • a heart valve disorder; or




  • a history of jaundice caused by birth control pills.



Before using this medication, tell your doctor if you have:



  • high blood pressure, heart disease, congestive heart failure, angina (chest pain), or a history of heart attack;




  • high cholesterol or if you are overweight;




  • a history of depression;




  • gallbladder disease;




  • diabetes;




  • seizures or epilepsy;




  • a history of irregular menstrual cycles;




  • a history of fibrocystic breast disease, lumps, nodules, or an abnormal mammogram;




  • uterine fibroid tumors;




  • varicose veins; or




  • tuberculosis.




The hormones in birth control pills can pass into breast milk and may harm a nursing baby. This medication may also slow breast milk production. Do not use if you are breast-feeding a baby.

How should I take Trivora-28 (ethinyl estradiol and levonorgestrel)?


Take this medication exactly as it was prescribed for you. Do not take larger amounts, or take it for longer than recommended by your doctor. You will take your first pill on the first day of your period or on the first Sunday after your period begins (follow your doctor's instructions).


You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medication. Follow your doctor's instructions.


Some 28-day birth control packs contain seven "reminder" pills to keep you on your regular cycle. Your period will usually begin while you are using these reminder pills.


Breakthrough bleeding may occur, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.

Take one pill every day, no more than 24 hours apart. When the pills run out, start a new pack the next day. You may get pregnant if you do not use this medication regularly.


If you need to have any type of medical tests or surgery, or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using birth control pills.


Store this medication at room temperature away from moisture and heat.

What happens if I miss a dose?


Missing a pill increases your risk of becoming pregnant.


If you miss one "active" pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.


If you miss two "active" pills in a row in week one or two, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.


If you miss two "active" pills in a row in week three, or if you miss three pills in a row during any of the first 3 weeks, throw out the rest of the pack and start a new one the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new one that day.


If you miss three "active" pills in a row during any of the first 3 weeks, throw out the rest of the pack and start a new pack on the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new one that day.


If you miss two or more pills, you may not have a period during the month. If you miss a period for two months in a row, call your doctor because you might be pregnant.

If you miss any reminder pills, throw them away and keep taking one pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill.


What happens if I overdose?


Seek emergency medical attention if you think you have used too much of this medicine. Overdose symptoms may include nausea, vomiting, and vaginal bleeding.


What should I avoid while taking Trivora-28 (ethinyl estradiol and levonorgestrel)?


Do not smoke while using birth control pills, especially if you are older than 35. Smoking can increase your risk of blood clots, stroke, or heart attack caused by birth control pills.

Birth control pills will not protect you from sexually transmitted diseases--including HIV and AIDS. Using a condom is the only way to protect yourself from these diseases.

Dosage Form: tablets
FULL PRESCRIBING INFORMATION
WARNING: CARDIOVASCULAR DISORDERS, BREAST CANCER, ENDOMETRIAL CANCER and PROBABLE DEMENTIA

Estrogen Plus Progestin Therapy




Cardiovascular Disorders and Probable Dementia


Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.3), and Clinical Studies (14.5, 14.6)].




The Women’s Health Initiative (WHI) estrogen plus progestin substudy reported increased risks of deep vein thrombosis (DVT), pulmonary embolism, (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo [see Warnings and Precautions (5.1), and Clinical Studies (14.5)].




The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [see Warnings and Precautions (5.3), Use in Specific Populations (8.5), and Clinical Studies (14.6)].




Breast Cancer


The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer [see Warnings and Precautions (5.2), and Clinical Studies (14.5)].




In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and MPA and other combinations and dosage forms of estrogens and progestins.




Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.




Estrogen-Alone Therapy




Endometrial Cancer


There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Adequate diagnostic measures, including directed or random endometrial sampling when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding [see Warnings and Precautions (5.2)].


Cardiovascular Disorders and Probable Dementia


Estrogen-alone therapy should not be used for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1 and 5.3), and Clinical Studies (14.5, 14.6)].




The WHI estrogen-alone substudy reported increased risks of stroke and DVT in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral CE (0.625 mg)-alone, relative to placebo [see Warnings and Precautions (5.1), and Clinical Studies (14.5)].




The WHIMS estrogen-alone ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 5.2 years of treatment with daily CE (0.625 mg)-alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women [see Warnings and Precautions (5.3), Use in Specific Populations (8.5), and Clinical Studies (14.6)].




In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and other dosage forms of estrogens.




Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.




Indications and Usage for Femhrt



Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause



Prevention of Postmenopausal Osteoporosis



Femhrt Dosage and Administration


Use of estrogen-alone, or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Postmenopausal women should be re-evaluated periodically as clinically appropriate to determine if treatment is still necessary.



Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause


Femhrt therapy consists of a single tablet to be taken orally once daily.



Prevention of Postmenopausal Osteoporosis


Femhrt therapy consists of a single tablet taken orally once daily.


When prescribing solely for the prevention of postmenopausal osteoporosis, therapy should be considered for women at significant risk of osteoporosis and non-estrogen medications should be carefully considered.



Dosage Forms and Strengths


The following two strengths of Femhrt are available:


Femhrt (0.5 mg/2.5 mcg): Each oval white tablet contains 0.5 mg norethindrone acetate and 2.5 mcg ethinyl estradiol;


Femhrt (1 mg/5 mcg): Each D-shaped white tablet contains 1 mg norethindrone acetate and 5 mcg ethinyl estradiol.



Contraindications


Femhrt should not be used in women with any of the following conditions:


  • Undiagnosed abnormal genital bleeding

  • Known, suspected, or history of breast cancer

  • Known or suspected estrogen-dependent neoplasia

  • Active DVT, PE or a history of these conditions

  • Active arterial thromboembolic disease (for example, stroke and MI), or a history of these conditions

  •  Known anaphylactic reaction or angioedema to Femhrt

  • Known liver dysfunction or disease

  • Known or suspected pregnancy


Warnings and Precautions



Cardiovascular Disorders


An increased risk of PE, DVT, stroke, and MI has been reported with estrogen plus progestin therapy. An increased risk of stroke and DVT has been reported with estrogen-alone therapy. Should any of these occur or be suspected, estrogen with or without progestin therapy should be discontinued immediately.


Risk factors for arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus) should be managed appropriately.


Stroke


In the WHI estrogen plus progestin substudy, a statistically significant increased risk of stroke was reported in women 50 to 79 years of age receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women in the same age group receiving placebo (33 versus 25 per 10,000 women- years) [see Clinical Studies (14.5)]. The increase in risk was demonstrated after the first year and persisted.1 Should a stroke occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.


In the WHI estrogen-alone substudy, a statistically significant increased risk of stroke was reported in women 50 to 79 years of age receiving daily conjugated estrogens CE (0.625 mg)-alone compared to women in the same age group receiving placebo (45 versus 33 per 10,000 women-years). The increase in risk was demonstrated in year 1 and persisted [see Clinical Studies (14.5)]. Should a stroke occur or be suspected, estrogen-alone therapy should be discontinued immediately.


Subgroup analyses of women 50 to 59 years of age suggest no increased risk of stroke for those women receiving CE (0.625 mg)-alone versus those receiving placebo (18 versus 21 per 10,000 women-years).1


Coronary Heart Disease


In the WHI estrogen plus progestin substudy, there was a statistically non-significant increased risk of coronary heart disease (CHD) events (defined as non-fatal MI, silent MI, or CHD death) reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (41 versus 34 per 10,000 women-years).1 An increase in relative risk was demonstrated in year 1, and a trend toward decreasing relative risk was reported in years 2 through 5 [see Clinical Studies (14.5)].


In the WHI estrogen-alone substudy, no overall effect on CHD events was reported in women receiving estrogen-alone compared to placebo2[see Clinical Studies (14.5)].


Subgroup analyses of women 50 to 59 years of age suggest a statistically non-significant reduction in CHD events (CE [0.625 mg]-alone compared to placebo) in women with less than 10 years since menopause (8 versus 16 per 10,000 woman-years).1


In postmenopausal women with documented heart disease (n = 2,763), average 66.7 years of age, in a controlled clinical trial of secondary prevention of cardiovascular disease (Heart and Estrogen/Progestin Replacement Study [HERS]), treatment with daily CE (0.625 mg) plus MPA (2.5 mg) demonstrated no cardiovascular benefit. During an average follow-up of 4.1 years, treatment with CE plus MPA did not reduce the overall rate of CHD events in postmenopausal women with established CHD. There were more CHD events in the CE plus MPA-treated group than in the placebo group in year 1, but not during the subsequent years. Two thousand three hundred and twenty one (2,321) women from the original HERS trial agreed to participate in an open label extension of HERS, HERS II. Average follow-up in HERS II was an additional 2.7 years, for a total of 6.8 years overall. Rates of CHD events were comparable among women in the CE plus MPA group and the placebo group in HERS, HERS II, and overall.


Venous Thromboembolism


In the WHI estrogen plus progestin substudy, a statistically significant 2-fold greater rate of VTE (DVT and PE) was reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (35 versus 17 per 10,000 women-years). Statistically significant increases in risk for both DVT (26 versus 13 per 10,000 women-years) and PE (18 versus 8 per 10,000 women-years) were also demonstrated. The increase in VTE risk was observed during the first year and persisted3[see Clinical Studies (14.5)]. Should a VTE occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.


In the WHI estrogen-alone substudy, the risk of VTE was increased for women receiving daily CE (0.625 mg)-alone compared to placebo (30 versus 22 per 10,000 women-years), although only the increased risk of DVT reached statistical significance (23 versus 15 per 10,000 women-years). The increase in VTE risk was demonstrated during the first 2 years4[see Clinical Studies (14.5)]. Should a VTE occur or be suspected, estrogen-alone therapy should be discontinued immediately.


If feasible, estrogens should be discontinued at least 4 to 6 weeks before surgery of the type associated with an increased risk of thromboembolism or during periods of prolonged immobilization.



Malignant Neoplasms


Breast Cancer


The most important randomized clinical trial providing information about breast cancer in estrogen plus progestin users is the WHI substudy of daily CE (0.625 mg) plus MPA (2.5 mg). After a mean follow-up of 5.6 years, the estrogen plus progestin substudy reported an increased risk of invasive breast cancer in women who took daily CE plus MPA. In this substudy, prior use of estrogen-alone or estrogen plus progestin therapy was reported by 26 percent of the women. The relative risk of invasive breast cancer was 1.24, and the absolute risk was 41 versus 33 cases per 10,000 women-years for estrogen plus progestin compared with placebo. Among women who reported prior use of hormone therapy, the relative risk of invasive breast cancer was 1.86 and the absolute risk was 46 versus 25 cases per 10,000 women-years for CE plus MPA compared with placebo. Among women who reported no prior use of hormone therapy, the relative risk of invasive breast cancer was 1.09, and the absolute risk was 40 versus 36 cases per 10,000 women-years for CE plus MPA compared with placebo. In the same substudy, invasive breast cancers were larger, were more likely to be node positive, and were diagnosed at a more advanced stage in the CE (0.625 mg) plus MPA (2.5 mg) group compared with the placebo group. Metastatic disease was rare with no apparent difference between the two groups. Other prognostic factors, such as histologic subtype, grade and hormone receptor status did not differ between the groups5[see Clinical Studies (14.5)].


The most important randomized clinical trial providing information about breast cancer in estrogen-alone users is the WHI substudy of daily CE (0.625 mg)-alone. In the WHI estrogen-alone substudy, after an average follow up of 7.1 years, daily CE-alone was not associated with an increased risk of invasive breast cancer (relative risk [RR] 0.80)6[see Clinical Studies (14.5)].


Consistent with the WHI clinical trials, observational studies have also reported an increased risk of breast cancer for estrogen plus progestin therapy, and a smaller increased risk for estrogen-alone therapy, after several years of use. The risk increased with duration of use, and appeared to return to baseline over about 5 years after stopping treatment (only the observational studies have substantial data on risk after stopping). Observational studies also suggest that the risk of breast cancer was greater, and became apparent earlier, with estrogen plus progestin therapy as compared to estrogen-alone therapy. However, these studies have not found significant variation in the risk of breast cancer among different estrogens or among different estrogen plus progestin combinations, doses, or routes of administration.


The use of estrogen-alone and estrogen plus progestin has been reported to result in an increase in abnormal mammograms requiring further evaluation.


All women should receive yearly breast examinations by a healthcare provider and perform monthly breast self-examinations. In addition, mammography examinations should be scheduled based on patient age, risk factors and prior mammogram results.


Endometrial Cancer


Endometrial hyperplasia (a possible precursor of endometrial cancer) has been reported to occur at a rate of approximately 1 percent or less with Femhrt.


An increased risk of endometrial cancer has been reported with the use of unopposed estrogen therapy in a woman with a uterus. The reported endometrial cancer risk among unopposed estrogen users is about 2 to 12 times greater than in non-users, and appears dependent on duration of treatment and on estrogen dose. Most studies show no significant increased risk associated with use of estrogens for less than 1 year. The greatest risk appears associated with prolonged use, with increased risks of 15- to 24-fold for 5 to 10 years or more, and this risk has been shown to persist for at least 8 to 15 years after estrogen therapy is discontinued.


Clinical surveillance of all women using estrogen-alone or estrogen plus progestin therapy is important. Adequate diagnostic measures, including directed or random endometrial sampling when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.


There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding a progestin to estrogen therapy in postmenopausal women has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.


Ovarian Cancer


The WHI estrogen plus progestin substudy reported a statistically non-significant increased risk of ovarian cancer. After an average follow-up of 5.6 years, the relative risk for ovarian cancer for CE plus MPA versus placebo was 1.58 [95 percent nominal confidence interval (nCI), 0.77-3.24]. The absolute risk for CE plus MPA versus placebo was 4 versus 3 cases per 10,000 women-years.7 In some epidemiologic studies, the use of estrogen plus progestin and estrogen-only products, in particular for 5 or more years, has been associated with an increased risk of ovarian cancer. However, the duration of exposure associated with increased risk is not consistent across all epidemiologic studies and some report no association.



Probable Dementia


In the WHIMS estrogen plus progestin ancillary study of WHI, a population of 4,532 postmenopausal women 65 to 79 years of age was randomized to daily CE (0.625 mg) plus MPA (2.5 mg) or placebo.


After an average follow-up of 4 years, 40 women in the CE plus MPA group and 21 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21-3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years8[see Use in Specific Populations (8.5), and Clinical Studies (14.6)].


In the WHIMS estrogen-alone ancillary study of WHI, a population of 2,947 hysterectomized women 65 to 79 years of age was randomized to daily CE (0.625 mg)-alone or placebo.


After an average follow-up of 5.2 years, 28 women in the estrogen-alone group and 19 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE-alone versus placebo was 1.49 (95 percent CI, 0.83-2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.6)].


When data from the two populations in the WHIMS estrogen-alone and estrogen plus progestin ancillary studies were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95 percent CI, 1.19-2.60). Since both ancillary substudies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8[see Use in Specific Populations (8.5), and Clinical Studies (14.6)].



Gallbladder Disease


A 2- to 4-fold increase in the risk of gallbladder disease requiring surgery in postmenopausal women receiving estrogens has been reported.



Hypercalcemia


Estrogen administration may lead to severe hypercalcemia in women with breast cancer and bone metastases. If hypercalcemia occurs, use of the drug should be stopped and appropriate measures taken to reduce the serum calcium level.



Visual Abnormalities


Retinal vascular thrombosis has been reported in women receiving estrogens. Discontinue medication pending examination if there is sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia, or migraine. If examination reveals papilledema or retinal vascular lesions, estrogens should be permanently discontinued.



Addition of a Progestin When a Woman Has Not Had a Hysterectomy


Studies of the addition of a progestin for 10 or more days of a cycle of estrogen administration or daily with estrogen in a continuous regimen, have reported a lowered incidence of endometrial hyperplasia than would be induced by estrogen treatment alone. Endometrial hyperplasia may be a precursor to endometrial cancer.


There are, however, possible risks that may be associated with the use of progestins with estrogens compared to estrogen-alone regimens. These include an increased risk of breast cancer.



Elevated Blood Pressure


In a small number of case reports, substantial increases in blood pressure have been attributed to idiosyncratic reactions to estrogens. In a large, randomized, placebo-controlled clinical trial, a generalized effect of estrogen therapy on blood pressure was not seen.



Hypertriglyceridemia


In women with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Consider discontinuation of treatment if pancreatitis occurs.



Hepatic Impairment and/or a Past History of Cholestatic Jaundice


Estrogens may be poorly metabolized in women with impaired liver function. For women with a history of cholestatic jaundice associated with past estrogen use or with pregnancy, caution should be exercised and in the case of recurrence, medication should be discontinued.



Hypothyroidism


Estrogen administration leads to increased thyroid-binding globulin (TBG) levels. Women with normal thyroid function can compensate for the increased TBG by making more thyroid hormone, thus maintaining free T4 and T3 serum concentrations in the normal range. Women dependent on thyroid hormone replacement therapy who are also receiving estrogen may require increased doses of their thyroid replacement therapy. These women should have their thyroid function monitored in order to maintain their free thyroid hormone levels in an acceptable range.



Fluid Retention


Estrogens plus progestins may cause some degree of fluid retention. Women with conditions that might be influenced by this factor, such as cardiac or renal dysfunction, warrant careful observation when estrogens plus progestins are prescribed.



Hypocalcemia


Estrogen therapy should be used with caution in women with hypoparathyroidism as estrogen-induced hypocalcemia may occur.



Exacerbation of Endometriosis


A few cases of malignant transformation of residual endometrial implants have been reported in women treated post-hysterectomy with estrogen-alone therapy. For women known to have residual endometriosis post-hysterectomy, the addition of progestin should be considered.



Exacerbation of Other Conditions


Estrogen therapy may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus and hepatic hemangiomas, and should be used with caution in women with these conditions.



Laboratory Tests


Serum follicle stimulating hormone (FSH) and estradiol levels have not been shown to be useful in the management of moderate to severe vasomotor symptoms.



Drug-Laboratory Test Interactions


Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of antifactor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity.


Increased thyroid-binding globulin (TBG) levels leading to increased circulating total thyroid hormone levels as measured by protein-bound iodine (PBI), T4 levels (by column or by radioimmunoassay) or T3 levels by radioimmunoassay. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Women on thyroid replacement therapy may require higher doses of thyroid hormone.


Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone-binding globulin (SHBG), leading to increased total circulating corticosteroids and sex steroids, respectively. Femhrt 1/5 was associated with an SHBG increase of 22 percent. Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin).


Increased plasma high-density lipoprotein (HDL) and HDL2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, increased triglycerides levels.


Impaired glucose tolerance.



Adverse Reactions


The following serious adverse reactions are discussed elsewhere in the labeling:


  • Cardiovascular Disorders [seeBoxed Warning, Warnings and Precautions (5.1)].

  • Malignant Neoplasms [seeBoxed Warning, Warnings and Precautions (5.2)].


Clinical Trials Experience


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Additional postmarketing adverse reactions have been reported in patients receiving other forms of hormone therapy.



Drug Interactions


No drug interaction studies have been conducted for Femhrt.



Metabolic Interactions


In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John’s wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in side effects.



Increase in Plasma Levels of Ethinyl Estradiol Associated with Co-Administered Drugs


Co-administration of atorvastatin and certain hormonal products containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20 percent. Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol levels, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole or ketoconazole may increase plasma hormone levels.



Changes in Plasma Levels of Co-Administered Drugs


Combination hormonal products containing some synthetic estrogens (for example, ethinyl estradiol) may inhibit the metabolism of other compounds. Combination hormonal products have been shown to significantly decrease plasma concentrations of lamotrigine likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary.



USE IN SPECIFIC POPULATIONS



Pregnancy


Femhrt should not be used during pregnancy [see Contraindications (4)]. There appears to be little or no increased risk of birth defects in children born to women who have used estrogens and progestins as an oral contraceptive inadvertently during early pregnancy.



Nursing Mothers


Femhrt should not be used during lactation. Estrogen administration to nursing women has been shown to decrease the quantity and quality of the breast milk. Detectable amounts of estrogen and progestin have been identified in the breast milk of women receiving estrogen therapy. Caution should be exercised when Femhrt is administered to a nursing woman.



Pediatric Use


Femhrt is not indicated in children. Clinical studies have not been conducted in the pediatric population.



Geriatric Use


There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Femhrt to determine whether those over 65 years of age differ from younger subjects in their response to Femhrt.


The Women’s Health Initiative Study


In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.5)].


In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.5)].


The Women’s Health Initiative Memory Study


In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen plus progestin or estrogen-alone when compared to placebo [see Warnings and Precautions (5.3), and Clinical Studies (14.6)].


Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8[see Warnings and Precautions (5.3), and Clinical Studies (14.6)].



Renal Impairment


The effects of renal impairment on the pharmacokinetics of Femhrt in postmenopausal women have not been studied.


In premenopausal women with chronic renal failure undergoing peritoneal dialysis who received multiple doses of an oral contraceptive containing ethinyl estradiol and norethindrone, plasma ethinyl estradiol concentrations were higher and norethindrone concentrations were unchanged compared to concentrations in premenopausal women with normal renal function [see Warnings and Precautions (5.12)].



Hepatic Impairment


The effects of hepatic impairment on the pharmacokinetics of Femhrt have not been studied.



Overdosage


Overdosage of estrogen plus progestin may cause nausea, vomiting, breast tenderness, abdominal pain, drowsiness and fatigue, and withdrawal bleeding may occur in women. Treatment of overdose consists of discontinuation of Femhrt with institution of appropriate symptomatic care.

Femhrt - Clinical Pharmacology



Mechanism of Action


Endogenous estrogens are largely responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Although circulating estrogens exist in a dynamic equilibrium of metabolic interconversions, estradiol is the principal intracellular human estrogen and is substantially more potent than its metabolites, estrone and estriol, at the receptor level.


The primary source of estrogen in normally cycling adult women is the ovarian follicle, which secretes 70 to 500 mcg of estradiol daily, depending on the phase of the menstrual cycle. After menopause, most endogenous estrogen is produced by conversion of androstenedione, which is secreted by the adrenal cortex, to estrone in the peripheral tissues. Thus, estrone and the sulfate conjugated form, estrone sulfate, are the most abundant circulating estrogens in postmenopausal women. The pharmacologic effects of ethinyl estradiol are similar to those of endogenous estrogens.


Estrogens act through binding to nuclear receptors in estrogen-responsive tissues. To date, two estrogen receptors have been identified. These vary in proportion from tissue to tissue.


Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and FSH through a negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.


Progestin compounds enhance cellular differentiation and generally oppose the actions of estrogens by decreasing estrogen receptor levels, increasing local metabolism of estrogens to less active metabolites, or inducing gene products that blunt cellular responses to estrogen. Progestins exert their effects in target cells by binding to specific progesterone receptors that interact with progesterone response elements in target genes. Progesterone receptors have been identified in the female reproductive tract, breast, pituitary, hypothalamus, bone, skeletal tissue and central nervous system. Progestins produce similar endometrial changes to those of the naturally occurring hormone progesterone.



Pharmacodynamics


Currently, there are no pharmacodynamic data known for Femhrt.



Pharmacokinetics


Absorption


Norethindrone acetate (NA) is completely and rapidly deacetylated to norethindrone after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate and ethinyl estradiol (EE) are rapidly absorbed from Femhrt tablets, with maximum plasma concentrations of norethindrone and ethinyl estradiol generally occurring 1 to 2 hours postdose. Both are subject to first-pass metabolism after oral dosing, resulting in an absolute bioavailability of approximately 64 percent for norethindrone and 55 percent for ethinyl estradiol. Bioavailability of Femhrt tablets is similar to that from solution for norethindrone and slightly less for ethinyl estradiol. Administration of Femhrt tablets with a high fat meal decreases rate but not extent of ethinyl estradiol absorption. The extent of norethindrone absorption is increased by 27 percent following administration of Femhrt tablets with food.


The full pharmacokinetic profile of Femhrt tablets was not characterized due to assay sensitivity limitations. However, the multiple-dose pharmacokinetics were studied at a dose of 1 mg NA/10 mcg EE in 18 post-menopausal women. Mean plasma concentrations are shown below (Figure 1) and pharmacokinetic parameters are found in Table 1. Based on a population pharmacokinetic analysis, mean steady-state concentrations of norethindrone for 1 mg NA/5 mcg EE and 1/10 are slightly more than proportional to dose when compared to 0.5 mg NA/2.5 mcg EE tablets. It can be explained by higher SHBG concentrations. Mean steady-state plasma concentrations of ethinyl estradiol for the Femhrt 0.5/2.5 tablets and Femhrt 1/5 tablets are proportional to dose, but there is a less than proportional increase in steady-state concentrations for the NA/EE 1/10 tablet.
