Zovirax (acyclovir) for Chickenpox is usually taken for about 5?7 days, and even if fever settles in 2 days, new blisters can still appear for a few days before drying and crusting. This is normal, so continue the full course as prescribed along with good skin care and hygiene. If blisters keep increasing after 4?5 days, or there is severe pain, pus, or high fever again, consult your doctor

Since you are on Zovirax 800 mg and on day 6 of treatment, your herpes blisters and mouth ulcers should start healing soon. You can apply a mild antiviral cream on the lip blisters if advised by your doctor. Keep the area clean, avoid spicy or acidic foods, and stay well hydrated.

Chickenpox is usually a viral illness that settles on its own, so treatment mainly focuses on relieving symptoms and preventing complications. You can take Paracetamol for fever and body aches, and apply calamine lotion to reduce itching; in some cases, a doctor may prescribe an antihistamine for severe itching. Keep yourself well hydrated, eat light, nutritious food, take adequate rest, and avoid scratching the blisters to prevent infection and scarring; keep nails short and wear loose clothing. Maintain good hygiene and stay isolated until all blisters dry and form scabs to avoid spreading the infection. In certain cases (like adults, severe symptoms, or high-risk patients), a doctor may prescribe antiviral medicines, so consult your doctor if symptoms are severe, persistent, or if you develop complications like high fever or breathing difficulty.
