What Is the First Treatment for Chickenpox?

Chickenpox, also called varicella, causes an itchy blistering rash that appears in crops. Initial care focuses on comfort, fluids, keeping nails short, and preventing scratching so the blisters are less likely to become infected. A GP can confirm the diagnosis and consider age, pregnancy, immune status, timing of the rash, and illness severity.

Antiviral treatment is time-sensitive and is not suitable for everyone. A clinician may consider it for people at higher risk of complications or when the illness is more severe. An oral antihistamine may help itching when a suitable product is recommended.

Keep the skin cool, wear loose clothing, and avoid scratching. Wash hands after touching the rash and avoid close contact with pregnant people, newborn babies, and anyone with a weakened immune system until a clinician says the contagious period has passed. Do not give aspirin to a child with chickenpox; ask a clinician which fever medicine is suitable.

See [Chickenpox](/conditions/chickenpox/) or arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if you are unsure of the diagnosis.

Seek urgent medical advice for breathing difficulty, unusual drowsiness, confusion, severe headache, repeated vomiting, dehydration, a very painful or rapidly reddening blister, or a rash involving the eye. Contact a clinician promptly if the person is pregnant, very young, immunocompromised, or taking immune-suppressing medicine.

Ask whether antiviral treatment is appropriate, how to control itching, which fever medicine is safe, and when the person can return to school or work. Tell the clinician when the rash began and whether there has been contact with someone vulnerable.
