Varicella
Varicella, better known as chickenpox, is a highly contagious viral infection caused by the varicella-zoster virus. It mostly affects children and usually shows up as an itchy rash that blisters and scabs over.
Key points
- Up to 90 percent of non-immune people in close contact with someone who has chickenpox will become infected.
- The illness usually resolves on its own within one to two weeks.
- For most people, chickenpox is managed at home with supportive measures to relieve symptoms and prevent skin infections.
Medicines listed for Varicella
The three products listed for varicella are all antiviral tablets. Valaciclovir appears in Valtrex (500 mg and 1000 mg), Aciclovir in Zovirax (200 mg, 400 mg and 800 mg), and Famciclovir in Famvir (250 mg and 500 mg). These antivirals target the varicella-zoster virus, which causes chickenpox and can later reactivate as shingles.
