Around 68% had symptom improvement.

How was this measured?▾

Ospemifene is FDA-approved for dyspareunia (painful sex) due to vaginal atrophy, not for hot flashes and night sweats. Phase III trials for dyspareunia: 68% had symptom improvement and 58% had relief with ospemifene vs 54% and 42% with placebo. NAMS 2023 does not list SERMs as a primary hot flash therapy.

The science

How it works in the body

SERMs bind to estrogen receptors and act like estrogen in some tissues (bone, vagina) while blocking estrogen in others (breast, uterus). This tissue-selective action can treat menopause symptoms without systemic estrogen.

What to know about Vaginal Dryness Pills

What it is

Selective estrogen receptor modulators (SERMs) are prescription pills that bind to estrogen receptors and act like estrogen in some tissues while blocking estrogen in others. This tissue-selective action can treat specific menopause symptoms without systemic estrogen. Ospemifene is FDA-approved for painful sex due to vaginal changes after menopause, a condition called genitourinary syndrome of menopause (GSM).

How well it works

SERMs are not a primary therapy for hot flashes and night sweats. The Menopause Society (NAMS 2023) does not list them as a first-line treatment for those symptoms. Ospemifene is FDA-approved for moderate-to-severe dyspareunia (painful sex) due to vaginal atrophy. In Phase III trials, 68% of ospemifene users had symptom improvement and 58% had relief, compared with 54% and 42% with placebo.

Side effects and cautions

Ospemifene carries an FDA boxed warning about the risks of endometrial cancer and cardiovascular disorders, including stroke and deep vein thrombosis. SERMs are not estrogen and do not replace hormones, but they still bind to estrogen receptors. That means ospemifene is not a good fit if you have a history of estrogen-dependent cancer, active or previous blood clots (DVT/PE) or arterial thromboembolic disease (stroke/MI), unexplained abnormal genital bleeding, are pregnant or may be pregnant, or are allergic to ospemifene. If you have severe liver problems, talk to your clinician about whether ospemifene is appropriate. Common side effects include hot flashes (paradoxically in some users), vaginal discharge, and muscle spasms.

Where to get it

You need a prescription, which you can get through telehealth or a menopause specialist.
