Why is Acyclovir prescribed during pregnancy?

If the herpes virus once enters the body, then it remains there until the end of life. A strong immune system produces antibodies to it, and thanks to this, herpes is not able to multiply freely.Then, being in the latent phase, he expects a decrease in immunity when he gets the opportunity to attack the body. As you know, the period of pregnancy is characterized by a decrease in the defenses of the woman’s body, and therefore this condition is most convenient for activating herpes.

In the case when infection with herpes occurred before pregnancy, the body of the woman develops antibodies that help protect the fetus from infection. If the infection occurred after conception, then “Acyclovir” is prescribed to pregnant women to prevent serious complications for the fetus.

In obstetric practice, drinking “Acyclovir” during pregnancy is often offered. This antiviral drug is capable of deleterious effects on different types of herpes. Against the background of his intake, there comes a cure of herpes zoster, genital herpes, chickenpox.

Important! The active substance "Acyclovir" in tablets easily bypasses the placental barrier, entering the body of the child. However, during the treatment with this drug, the development of intrauterine pathologies that could have formed against the background of infection with herpes was not revealed.

Doctors say herpes exposure is far more dangerous than Acyclovir. The virus negatively affects the formation of all organs and systems of the fetus, during pregnancy. During infection, a miscarriage, a missed pregnancy, and premature birth can occur.
