How does this medication work? What will it do for me?
This medication belongs to a family of medications known as vaccines. It is used to prevent shingles for people over 50 years of age. Shingles is caused by the same virus that causes chickenpox. After you have had chickenpox, the virus retreats to the nerves, where it lies dormant for years.
Shingles occurs when the virus becomes active again, causing a blistering rash and severe burning pain. The medication works by boosting the immune system to help prevent shingles. It does not treat shingles.
