What is Premarin?
Premarin is a medication used to treat moderate to severe symptoms of vulvar and vaginal atrophy (VVA) due to menopause. It is also used to treat moderate to severe hot flashes in women [1]. The active ingredient in Premarin is a mixture of conjugated estrogens derived from pregnant mares' urine [1][2].
