It is also used to treat chickenpox and cold sores in children. In your body, valacyclovir becomes the anti-herpes medicine, acyclovir.

The antiviral drugs acyclovir, valacyclovir, and famciclovir are often prescribed to treat herpes viral infections, such as herpes simplex virus (HSV). More than one in five pregnant women have antibodies in their blood to HSV, indicating a past or present infection. Herpes antiviral medications are also used to treat herpes zoster infections, commonly known as shingles. Until now, information about the safety of these antivirals during pregnancy has been limited, according to background information in the journal article. The medications are listed as category B by the FDA. Benefit should outweigh risk AU TGA pregnancy category: B3US FDA pregnancy category: BComments: -Acyclovir (aciclovir) has been safely used to treat genital herpes in women in all stages of pregnancy; data on prenatal exposure to this prodrug is limited, however, animal data suggests low risk. -Women who acquire genital herpes simplex virus (HSV) during late pregnancy should be managed in consultation with maternal-fetal medicine and infectious-disease specialists. -Suppressive therapy late in pregnancy has been shown to reduce the frequency of cesarean delivery among women with recurrent genital herpes by diminishing the frequency of recurrences at term; such treatment may not protect against transmission to neonates in all cases. -Recommended regimen for HSV suppressive therapy in pregnant women with recurrent genital herpes: 500 mg orally 2 times a day starting at 36 weeks gestation. Animal studies have failed to reveal evidence of teratogenicity for either valacyclovir (valaciclovir) or acyclovir (aciclovir; the active metabolite). No significant neonatal toxicity or fetal drug accumulation was noted in a small pharmacokinetic study (n=20) of this drug (500 mg twice daily) administered beginning at 36 weeks' gestation. Pregnancy registry data reported 1 document exposures to this drug or any formulation of its active metabolite, respectively, of which 29 and 756 exposures occurred in the first trimester. Exposure did not indicate an increased incidence of major birth defects compared with the general population in a prospective pregnancy registry; however, there is insufficient data for definitive conclusions regarding exposure during pregnancy.
