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.
  • Tell your doctor about any unusual vaginal bleeding.
