Hello,
Thanks for posting your query.
Acyclovir has been assigned to pregnancy category B by the FDA. Nonstandard animal studies have produced fetal abnormalities, while standard animal testing failed to reveal evidence of teratogenicity.
Exposure to acyclovir in the first trimester of pregnancy is not associated with an increased risk for major birth defects. There is no increased risk for other problems such as low birth weight, preterm delivery, or stillbirth.
There is no need to worry about the congenital defects in the baby. You can safely continue with this pregnancy.
Viral infection which has been well treated in time is not likely to affect the baby at all.
I hope this answers your query effectively.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
Regards.

Hello,

Thanks for writing again.

Non standard animal studies are not considered standard to see the effect of a drug. The mechanism of fetal defects in animals can be considerably different from that in humans. These do not suggest of an increased risk of congenital defects in your baby. So do not worry.

Relapse of herpes Zoster infection usually occurs rarely if the treatment is complete. To prevent the re infection, the partner also needs to be treated adequately with anti viral drugs like acyclovir.

Hope my answer is helpful.

Wish you good health.

Regards.
