SERM
Strong evidence
Ospemifene (Osphena)
An oral non-hormonal tablet for painful sex and vaginal dryness. Most women have never heard of it.
30-second summary
Ospemifene is a selective estrogen receptor modulator (SERM) taken as a daily oral tablet for vaginal dryness and painful sex. It is FDA-approved for dyspareunia and is a genuine alternative to local vaginal estrogen for women who prefer a tablet to a cream or suppository. Strong evidence. Almost completely unknown among patients.
What it is
A SERM — it acts like estrogen on vaginal and bone tissue but not on breast tissue. Taken as a once-daily 60mg tablet. FDA-approved specifically for moderate to severe dyspareunia (painful sex) due to menopause.
What the evidence shows
Strong evidence from multiple randomised trials for significant improvement in vaginal dryness, painful sex, and vaginal tissue health. Also appears to have bone-protective effects. Does not increase breast cancer risk based on current evidence.
Honest about risks and side effects
Hot flashes are a paradoxical side effect in some women — the estrogen-like activity in the hypothalamus can trigger vasomotor symptoms. Not appropriate if hot flashes are already a significant problem. Mild increased stroke and clot risk similar to oral estrogen — lower than with systemic HRT.
What we do not know
Long-term safety data beyond 4 years is limited. Whether the bone-protective effect is clinically meaningful has not been established. Comparison with local vaginal estrogen in head-to-head trials is limited.
Who it is best for
Women with painful sex or vaginal dryness who prefer an oral tablet to vaginal application. Women who cannot use estrogen-containing products vaginally. Women who want a non-hormonal approach (despite acting on estrogen receptors, it is classified differently).
Who should be cautious
Women with significant hot flashes — can worsen them. Women with history of blood clots or stroke. Women on blood thinners.
How to access this
Requires a prescription. Less commonly prescribed than it should be — ask specifically if vaginal symptoms are your primary concern and you prefer an oral option.
Questions to ask your doctor
• Is ospemifene appropriate for my symptoms?
• How does it compare to local vaginal estrogen in my situation?
• Will it worsen my hot flashes?
• How long before I notice improvement?
Rose honest take
"Ospemifene is one of the most underused treatments in menopause medicine. Women spend years with painful sex that could be addressed. If local vaginal estrogen does not appeal to you, ask about this."
