Herpes Zoster
Herpes zoster, commonly known as shingles, is a painful rash infection caused by reactivation of the varicella-zoster virus in a person who has previously had chickenpox.
Key points
- The rash typically appears on one side of the body, often the chest or abdomen, and is usually painful, itchy, or tingly.
- Antiviral medicines can shorten the illness and work best when started as soon as the rash appears.
- Long-term nerve pain called postherpetic neuralgia is a recognised complication that can persist for months after the rash resolves.
Medicines listed for Herpes Zoster
The listed products contain valaciclovir, aciclovir and famciclovir, all of which belong to the antiviral class. These medicines act against the varicella-zoster virus and are all in tablet form. Each targets the virus through a different active ingredient, the same virus behind shingles.
