What is the pregnancy category for Valacyclovir?

Valacyclovir falls into pregnancy category B. This classification refers to medications that, based on animal reproduction studies, have not demonstrated a risk to the fetus. Human studies are either not available or have demonstrated no risk to the fetus in the first trimester, and the possibility of harm appears remote.

In the case of Valacyclovir, studies in animals have not shown adverse effects, indicating that the risk associated with its use during pregnancy is low. Therefore, recognizing Valacyclovir's classification is crucial for healthcare providers prescribing medications to pregnant patients, ensuring they make informed decisions that prioritize both maternal and fetal health.

A response that indicates 'None' as a category does not accurately reflect the classification system used to assess drug safety during pregnancy. Instead, it is important to understand that Valacyclovir is categorized as B, confirming its relative safety in pregnant populations when benefits outweigh potential risks.
