Herpes simplex virus can provide a lot of trouble for its carriers. During the slightest weakening of immunity, it manifests itself in the form of a painful skin rash. After the appearance of lesions in the form of bubbles with liquid and complaints of burning, doctors often prescribe valacyclovir, which stops the synthesis of viral cells.

Action

Infections caused by the herpes simplex virus occupy fourth place in terms of global disease prevalence. Valacyclovir is an antiviral drug that can prevent the development of such diseases. Following penetration into the body, the herpes simplex virus remains in the human deoxyribonucleic acid. With a decrease in immunity, it is activated, causing the appearance of rashes on different parts of the patient’s body. Valacyclovir causes the destruction of the enzymes of the virus and the subsequent recovery of the patient.

Composition

The main active ingredient of the drug is valacyclovir hydrochloride. When this enters the body, it turns into acyclovir, accumulates in the blood plasma, and affects various types of herpes viruses. Tablets of this medication also contain additional components that facilitate the absorption of the drug and reduce the risk of side effects.
