Valtrex when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Valtrex (Valacyclovir) at 500mg, 1000mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Valacyclovir and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Valtrex
According to the prescribing information for Valacyclovir, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Antiviral Medications medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Valacyclovir is rapidly and almost completely converted to acyclovir during first-pass intestinal and hepatic metabolism by valacyclovir hydrolase.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Valtrex has any documented effect on fertility depends on Valacyclovir; the prescribing information notes any data. Anyone trying to conceive should discuss Valtrex with the prescriber and a fertility specialist if conception is taking longer than expected.
