Which of the following is a common side effect of Ospemifene?

Ospemifene is a selective estrogen receptor modulator (SERM) used primarily for the treatment of dyspareunia (painful intercourse) due to vulvar and vaginal atrophy associated with menopause. A common side effect of Ospemifene is hot flashes, which can occur in some women as the body responds to changes in estrogenic activity. This happens because SERMs can exert estrogen-like effects in some tissues while having anti-estrogen effects in others, leading to a complex interaction that can result in vasomotor symptoms like hot flashes.

The other options presented do not typically characterize the side effects associated with Ospemifene. Decreased sweating and weight loss are not widely recognized symptoms linked to its use, and while hypertension can occur for various reasons, it is not a common direct side effect of Ospemifene. Understanding this helps clarify the hormonal mechanisms at play in the management of menopausal symptoms and the potential side effects of treatments like Ospemifene.
