Frequently asked questions

Below are answers to some commonly asked questions about progesterone oral capsule and its dosage.

Can progesterone be taken for HRT, to treat infertility, or to prevent pregnancy loss? If so, what’s the dosage?

Progesterone oral tablet is not approved by the FDA for these purposes or conditions. But doctors sometimes prescribe medications off-label. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved to treat or help prevent.

Because of progesterone’s effects on the uterus, doctors might prescribe it for certain purposes. These could be to stop bleeding, treat infertility, prevent pregnancy loss (miscarriage), or as hormone replacement therapy (HRT). If you have questions about taking progesterone for one of these conditions, talk with your doctor.

Does progesterone have a twice-per-day dosage?

Progesterone is approved to be taken once per day for a specific number of days. But some doctors prescribe progesterone oral capsule for an off-label use, such as infertility. This means they prescribe a drug for a purpose other than what it’s approved to treat or help prevent. In this case, they might instruct you to take it twice per day.

Talk with your doctor to learn more about how often you should take your progesterone dose.

Is progesterone taken long term?

It depends on the condition progesterone oral capsule is being used for. Doctors may prescribe it long term for the prevention of endometrial hyperplasia if they determine it’s safe for you. But for the treatment of secondary amenorrhea, they’ll prescribe it short term.

If you have questions about how long you should take progesterone oral capsule, talk with your doctor.

How progesterone is taken
