Key takeaways
Premarin vaginal cream (conjugated estrogens) and Minivelle (estradiol patch) are both estrogen replacement medications used to treat symptoms related to menopause. While both medications are estrogen replacement therapies, they have some important differences.

Premarin is specifically used for vaginal symptoms, including dryness and irritation, whereas Minivelle also helps prevent bone loss (osteoporosis) after menopause. Premarin is applied in cycles or twice a week, while Minivelle is applied twice a week. Common side effects of Premarin include headache and pelvic pain, while Minivelle can cause headaches and breast tenderness. Both medications carry risks of serious side effects like blood clots and cancer and are only available in a branded version.
