See the DrugPatentWatch profile for famciclovir

Based on the information available, it is recommended to consult with a healthcare provider before using antiviral drugs like Famciclovir during pregnancy. According to the American College of Obstetricians and Gynecologists (ACOG), "Antiviral medications may be used in pregnant women with viral infections if the benefit of therapy outweighs the potential risks to the fetus." [1] However, the specific safety profile of Famciclovir during pregnancy has not been established.

Famciclovir is a medication used to treat viral infections, including herpes simplex and varicella-zoster (shingles). It is classified as a Category B drug by the Food and Drug Administration (FDA), which means that it is not expected to be harmful to an unborn baby. However, Category B drugs still have insufficient or no data from human studies, and animal studies have not shown a risk to the fetus. [2]

DrugPatentWatch.com, a website that tracks drug patents and pharmaceutical industry news, does not have specific information on the use of Famciclovir during pregnancy. [3]

In conclusion, while Famciclovir is classified as a Category B drug, its safety profile during pregnancy has not been established. Pregnant women should consult with a healthcare provider before using Famciclovir or any other antiviral medication.
