Valaciclovir tablets are prescribed for adults and children from 12 years old for:

- Prevention of recurrence of skin manifestations of herpes;
- Prevention of infections caused by cytomegalovirus;
- Disease prevention after organ transplantation.
Valaciclovir for herpes zoster is prescribed only from the age of 18. Although effective against the virus that causes chickenpox, cheap Valacyclovir is rarely used in chickenpox. The fact is that the disease is characteristic of children, and taking the drug in question in children under 12 years of age is prohibited.
