How it works
PremarinProvera
Premarin (Conjugated Estrogens) is an oral medication that replaces estrogen hormones during and after menopause. Higher levels of estrogen lower menopause-related hot flashes, flushing, night sweats, vaginal problems, and bone loss.Provera (Medroxyprogesterone) contains medroxyprogesterone, a progesterone hormone that works to balance hormone changes in the body. In premenopausal women, it prevents thickening of the uterus lining and regulates your menstrual cycle. It's also added to hormone therapy to protect the uterus from the harmful effects of estrogen.

      Tips from our pharmacists for people taking the medication
      PremarinProvera
      • Take Premarin (Conjugated Estrogens) at the same time each day. If you miss a dose, take it as soon as possible, but if it’s almost time for your next dose, take only that dose.
      • Use the lowest dose possible of Premarin (Conjugated Estrogens) and take it only as long as needed. Talk to your doctor regularly to see if you still need treatment. If you’re taking Premarin (Conjugated Estrogens) only for vaginal symptoms or to prevent bone loss, there are other medicines that can work better with fewer side effects (like a vaginal cream for menopause symptoms, or non-estrogen medicine for bone loss).
      • Can cause nausea, dizziness, bloating and breast tenderness.
      • Get emergency care if you notice swelling or pain in your lower legs, sudden shortness of breath, or an unexplained severe headache.
      • Tell your doctor about any unusual vaginal bleeding.
      • The dose of Provera (Medroxyprogesterone) will be different depending on what you’re using it for, so take it exactly the way your doctor tells you.
      • Talk to your doctor every few months about using the lowest possible dose of Provera (Medroxyprogesterone). Since there can be a lot of long-term side effects, take it only as long as you need it.
      • Can cause headache, weight gain, breast tenderness, or changes in mood.
      • If you're taking Provera (Medroxyprogesterone) to regulate your period, you'll get withdrawal bleeding 3 to 7 days after stopping Provera (Medroxyprogesterone).
