For the treatment of genital warts, trichloroacetic acid and physical modalities such as cryotherapy are felt to be safe in pregnancy. Imiquimod (category B) is minimally absorbed, and animal studies, as well as very limited data of use in pregnant women, have not shown adverse fetal effects.[22,23] Podophylline and podophyllotoxin (category C) are not recommended for use in pregnancy because of fetal abnormalities and deaths associated with maternal use.[24,25] Acyclovir, famciclovir and valacyclovir are all pregnancy category B, and pregnancy registries exist for each of these agents. No adverse effects on the fetus or newborn have been attributed to their use in pregnancy, but because we have more data on the use acyclovir in human pregnancy, some authors consider it to be the drug of choice when indicated in pregnancy.
