Key takeaways
Premarin vaginal cream (conjugated estrogens) and Vivelle-Dot (estradiol) patch are both estrogen replacement medications used to treat symptoms of menopause. However, they differ in several ways. Premarin is a vaginal cream specifically approved for treating vaginal symptoms, like dryness and irritation. Vivelle-Dot is a transdermal patch applied to the skin and is used for a broader range of menopause symptoms, including hot flashes and night sweats. Vivelle-Dot is also used to help prevent osteoporosis after menopause. Premarin only comes in a branded version, while Vivelle-Dot is available as a generic called Dotti. Premarin vaginal cream is applied in cycles or twice a week, while Vivelle-Dot is applied twice a week. Common side effects of Premarin include headache and pelvic pain, while Vivelle-Dot may cause headaches, breast tenderness, and sinus swelling. Both medications carry risks of serious side effects like blood clots and certain cancers.
