Valtrex has been studied in depth for quite some time. It is a pro drug for acyclovir, which has been around for 30 years. Valtrex turns into acyclovir after it is absorbed which allows your body to get more of the drug into your system for longer (which is why you take Valtrex less frequently than acyclovir). Although it has not been officially tested for use during pregnancy, it is considered safe to use when pregnant because it is a category "B" medication. There was somewhat of a study done on the correlation between Valtrex and pregnant women where about 1000 women were monitored. The results did indicate that the rate of defects amongst that group was considered to be the same as for women not taking any medication.

If you suffer from herpes then it is usually recommended to take Acyclovir or Valtrex at least during the last weeks of pregnancy. This will help to prevent an outbreak during childbirth. However, you are still passing the antibodies onto your infant. During the last weeks of pregnancy your child is less likely to suffer any ill effects from any medication you may take. This is not to say you should not weigh your options and make your own decisions.

Antiviral is completely different from antibiotics and just don’t wreak the havoc on your body that an antibiotic can. Valtrex/Acyclovir very specifically targets herpes by mimicking a substance the virus needs to reproduce. When the virus grabs onto the antiviral, the antiviral gets in the way of the virus being able to reproduce. The substance Valtrex/acyclovir mimics is not a substance your body needs so your body doesn’t tend to react to the drug much.
