What EZOVIR® is used for
EZOVIR® 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 EZOVIR® does not cure the viral infection, it helps to relive the symptoms and shorten their duration.
The best results are obtained if the medicine is started as soon as possible the first symptoms begin to appear.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
EZOVIR® is only available with a doctor's prescription. It is not addictive.
This medicine is not recommended for use in infants or children under 12 years of age.
