Valtrex and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Valtrex (Valacyclovir) is no exception. The prescribing information for Valacyclovir provides specific guidance, and the right decision depends on the indication, alternatives, gestational stage and the woman's overall medical picture.
Pregnancy safety data for Valtrex
According to the prescribing information for Valacyclovir, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some Antiviral Medications agents are routinely used in pregnancy when needed; others are avoided. The risk-benefit calculation includes the importance of treating the underlying condition and the consequences of leaving it untreated.
Breastfeeding considerations
Breastfeeding considerations are usually separate from pregnancy considerations. Some active ingredients pass into breast milk in negligible amounts; others are present at levels that warrant caution. Valacyclovir is rapidly and almost completely converted to acyclovir during first-pass intestinal and hepatic metabolism by valacyclovir hydrolase. The prescriber weighs the benefit of breastfeeding, the importance of Valtrex, and the availability of alternative therapies.
