Ospemifene

What is Ospemifene?

• Ospemifene (OSPHENA) is an estrogen agonist/antagonist used for the treatment of dyspareunia.

What are the uses of this medicine?

This medicine is used after menopause for women with or without a uterus to treat:

• Moderate to severe pain during sexual intercourse due to changes in and around your vagina.
• Moderate to severe vaginal dryness due to changes in and around your vagina.

How does this medicine work?

• Ospemifene has estrogen-like effects (agonism) on vaginal epithelium, but antiestrogen activity (antagonism) on breast tissue.
• This differential activity is keyed to achieving the beneficial effects of estrogens on vaginal secretions and epithelial integrity, while avoiding the potential harmful effects of estrogen stimulation of breast tissue.
• In several large clinical trials, ospemifene was shown to decrease symptoms of dyspareunia (vaginal dryness and discharge and pain on intercourse) without stimulating breast and uterine growth.

Who Should Not Use this medicine ?

This medicine cannot be used in patients who:

• have unusual vaginal bleeding. Vaginal bleeding after menopause may be a warning sign of cancer of the lining of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
