What does the patient leaflet for ospemifene say first?

The FDA-approved Medication Guide or Patient Information that comes with the medicine, in its own words.

From the patient leaflet: What is the most important information I should know about OSPHENA?

OSPHENA is a medicine that works like estrogen in the lining of the uterus (womb) but can work differently in other parts of the body. OSPHENA may increase your chance of getting cancer of the lining of the uterus (womb). 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. Tell your healthcare provider right away if you have any unusual vaginal bleeding while you are taking OSPHENA. OSPHENA may increase your chance of getting strokes and blood clots.

From the patient leaflet: How should I store OSPHENA?

Store OSPHENA at room temperature between 68°F to 77°F (20°C to 25°C). Keep OSPHENA and all medicines out of the reach of children.
