Progesterone Capsule Information

Progesterone capsules (Prometrium®) are approved to:
  • Cause a period in women who stopped having menstrual periods before menopause (secondary amenorrhea)
  • Prevent abnormal thickening of the lining of the uterus in women taking estrogen hormone replacement therapy.
The capsules come in two strengths and are typically taken once a day. Though generally well tolerated, they are not suitable for everyone. Before using progesterone capsules, make sure your healthcare provider has up-to-date information on your medical history and a list of your current medications. In particular, let your healthcare provider know if you have problems such as asthma, epilepsy, or migraines.
