WARNING: ENDOMETRIAL CANCER AND CARDIOVASCULAR DISORDERS
Endometrial Cancer
OSPHENA is an estrogen agonist/antagonist with tissue selective effects. In the endometrium, OSPHENA has estrogen agonistic effects. There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy reduces the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Adequate diagnostic measures, including directed and 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
There is a reported increased risk of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) who received daily oral conjugated estrogens (CE) [0.625 mg]-alone therapy over 7.1 years as part of the Women's Health Initiative (WHI) [see Warnings and Precautions (5.1)].
In the clinical trials for OSPHENA (duration of treatment up to 15 months), the incidence rates of thromboembolic and hemorrhagic stroke were 0.72 and 1.45 per thousand women, respectively in OSPHENA 60 mg treatment group and 1.04 and 0 in placebo [see Warnings and Precautions (5.1)]. The incidence of DVT was 1.45 per thousand women in OSPHENA 60 mg treatment group and 1.04 per thousand women in placebo [see Warnings and Precautions (5.1)]. OSPHENA should be prescribed for the shortest duration consistent with treatment goals and risks for the individual woman.
Overview
Ospemifene is a Selective Estrogen Receptor Modulator that is FDA approved for the treatment of moderate to severe dyspareunia, a symptom of vulvar and vaginal atrophy, due to menopause. There is a Black Box Warning for this drug as shown here. Common adverse reactions include hot flush, vaginal discharge, muscle spasms, genital discharge, hyperhidrosis..
Adult Indications and Dosage
FDA-Labeled Indications and Dosage (Adult)
Indications
OSPHENA is indicated for the treatment of moderate to severe dyspareunia, a symptom of vulvar and vaginal atrophy, due to menopause.
Dosage
OSPHENA is an estrogen agonist/antagonist which has agonistic effects on the endometrium. Generally, when a product with estrogen agonistic effects on the endometrium is prescribed for a postmenopausal woman with a uterus, a progestin should be considered to reduce the risk of endometrial cancer. A woman without a uterus does not need a progestin [see Warnings and Precautions (5.2)].
Use of OSPHENA should be 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.
2.1 Treatment of Moderate to Severe Dyspareunia, a Symptom of Vulvar and Vaginal Atrophy, due to Menopause
Take one 60 mg tablet with food once daily.
DOSAGE FORMS AND STRENGTHS
OSPHENA tablets are white to off-white, oval, biconvex, film coated tablets containing 60 mg of ospemifene and engraved with "60" on one side.

Contraindications
OSPHENA is contraindicated in women with any of the following conditions:
Undiagnosed abnormal genital bleeding
Known or suspected estrogen-dependent neoplasia
Active DVT, pulmonary embolism (PE), or a history of these conditions
Active arterial thromboembolic disease [for example, stroke and myocardial infarctions (MI)], or a history of these conditions
OSPHENA is contraindicated in women who are or may become pregnant. OSPHENA may cause fetal harm when administered to a pregnant woman. Ospemifene was embryo-fetal lethal with labor difficulties and increased pup deaths in rats at doses below clinical exposures, and embryo-fetal lethal in rabbits at 10 times the clinical exposure based on mg/m2. If this drug is used during pregnancy, or if a woman becomes pregnant while taking this drug, she should be apprised of the potential hazard to a fetus.
