Prometrium when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Prometrium (Progesterone) at 100mg, 200mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Progesterone and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Prometrium
According to the prescribing information for Progesterone, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Hormones and Birth Control medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Progesterone in Prometrium binds to progesterone receptors and modulates gene expression in reproductive and other tissues.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Prometrium has any documented effect on fertility depends on Progesterone; the prescribing information notes any data. Anyone trying to conceive should discuss Prometrium with the prescriber and a fertility specialist if conception is taking longer than expected.
