FAMVIR is an antiviral medicine that is used to treat shingles in adults and adolescents.
Shingles is a condition that is caused by a herpes virus called varicella zoster, the same virus that causes chicken pox. The virus can become active again in the body, even after many years, resulting in shingles. The main symptom is a rash that can cause pain, burning and blisters.
Although FAMVIR does not cure the viral infection, it helps to relieve the symptoms and shorten their duration.
The best results are obtained if the medicine is started as soon as possible after the first symptoms begin to appear.
