After reviewing the available information, there is no explicit mention of alternatives to Famciclovir specifically for pregnant women. However, the CDC guideline [${2}] does provide information on the treatment of genital herpes during pregnancy.

The CDC guideline [${2}] states that antiviral medications, such as Famciclovir, are an option for managing genital herpes during pregnancy. These antiviral medications can reduce the duration and severity of symptoms and the risk of transmission to the newborn.

However, the guideline [${2}] also notes that the safety of these antiviral medications during pregnancy has not been established. The guideline [${2}] recommends that decisions about treating genital herpes during pregnancy should be individualized and made in consultation with a healthcare provider.

The Uptodate resource [${3}] states that "valacyclovir and acyclovir are preferred over famciclovir during pregnancy because of their extensive safety data."

In conclusion, while Famciclovir is an option for treating genital herpes during pregnancy, it may not be the preferred choice due to limited safety data. Valacyclovir and acyclovir are considered safer alternatives during pregnancy. As with any medical condition, pregnant women should consult with their healthcare provider to determine the most appropriate treatment plan.
