Does antiviral treatment treat chickenpox?

Chickenpox is caused by varicella-zoster virus and commonly causes an itchy rash that changes into fluid-filled spots before crusting. Antiviral medicine acts on the virus and may be considered when illness is more severe or the person has a higher risk of complications. It is not suitable for everyone, and starting it late may change the expected benefit.

A clinician will consider the person’s age, pregnancy, immune health, lung or skin conditions, medicines, and the time since the rash began. Do not give a child or adult another person’s antiviral prescription. Avoid aspirin in children with chickenpox unless a clinician specifically advises otherwise.

Contact a clinician early if chickenpox is suspected, especially for an infant, adult, pregnant person, or someone with reduced immunity. Keep nails short, avoid scratching, use gentle skin care, and drink fluids. Stay away from people who are pregnant, newborn, or immunocompromised until a clinician confirms you are no longer infectious. Do not share towels or personal items.

Seek urgent help for breathing difficulty, severe drowsiness, confusion, repeated vomiting, dehydration, severe headache, trouble walking, or a rash near the eye. Prompt review is needed if spots become very red, hot, swollen, or painful, if fever returns after improving, or if the person appears significantly unwell. Call ahead before attending a clinic so staff can reduce exposure to others.

Ask whether antiviral treatment is appropriate now, how to relieve itch safely, how long to avoid close contact, which medicines to avoid, and which changes could indicate a secondary infection or another diagnosis.
