How it works
PremarinCombipatch
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.Combipatch (Estradiol / Norethindrone Patch) is an estrogen/progestin combination patch that works to balance hormone changes in your body during and after menopause. Estradiol (an estrogen) reduces hot flashes and night sweats and prevents bone loss, but can also harm cells in the uterus after menopause. Norethindrone (a progestin) protects the uterus from damage.

      Tips from our pharmacists for people taking the medication
      PremarinCombipatch
      • 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.

      • Remove the patch by tearing the package by hand and not with scissors. Never cut the patch.

      • Replace the patch twice a week (every 3-4 days) on a different area of your skin to lower your risk of skin irritation.
