Dual 5α-reductase inhibitor (type 1 and type 2)
Dutasteride when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Dutasteride (Dutasteride) at 0.5mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Dutasteride and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Dutasteride
According to the prescribing information for Dutasteride, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Dual 5α-reductase inhibitor (type 1 and type 2) medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Dutasteride irreversibly inhibits both isoenzymes of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT).
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Dutasteride has any documented effect on fertility depends on Dutasteride; the prescribing information notes any data. Anyone trying to conceive should discuss Dutasteride with the prescriber and a fertility specialist if conception is taking longer than expected.
