Outcome & guideline status

Recommended

Recommended by the Menopause Society for symptom relief.

68 out of 100 people had improvement in painful sex.

Around 68% had improvement in painful sex.

How was this measured?

Ospemifene is FDA-approved for moderate to severe dyspareunia (painful sex) and vaginal dryness due to menopause, not for hot flashes and night sweats. In Phase III Study 310, among women whose most bothersome symptom was dyspareunia, 68% had improvement and 58% had relief with ospemifene vs 54% and 42% with placebo; results were similar in Study 821. NAMS 2023 does not list SERMs among its recommended hot flash therapies.

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. Ospemifene is FDA-approved for moderate to severe painful sex and vaginal dryness caused by vaginal changes after menopause, part of a condition called genitourinary syndrome of menopause (GSM).

How well it works

Ospemifene does not treat hot flashes and night sweats; hot flashes are one of its common side effects. The NAMS 2023 position statement does not list SERMs among its recommended therapies for those symptoms. Ospemifene is FDA-approved for moderate to severe dyspareunia (painful sex) and vaginal dryness due to menopause. In a Phase III trial, 68% of women whose most bothersome symptom was painful sex had improvement and 58% had relief with ospemifene, 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. Ospemifene is not an estrogen, but it binds to estrogen receptors. That means it is not a good fit if you have an estrogen-dependent cancer or known, suspected or past breast cancer; active or previous blood clots (DVT/PE) or arterial thromboembolic disease (stroke/MI); or unexplained abnormal genital bleeding. It is also not for use if you are pregnant or may be pregnant, or are allergic to ospemifene. It should not be used if you have severe liver impairment. Common side effects include hot flashes (paradoxically in some users), vaginal discharge, and muscle spasms.
