Zovirax 400 Mg Tablet is an antiviral medicine used to treat infections caused by certain herpes viruses. It is commonly prescribed for chickenpox, shingles (herpes zoster), cold sores around the lips, and genital herpes infections.
It contains aciclovir, which belongs to a group of medicines called purine nucleoside analogues. It works by entering infected cells and blocking the viral enzyme needed for the virus to multiply and spread to healthy tissue. It can be taken with or without food.
Staying well hydrated by drinking plenty of water helps protect your kidneys during treatment. Keeping the affected skin clean and dry, wearing loose cotton clothing over the sores, and avoiding close contact with others helps reduce the risk of spreading the virus.
Tell your doctor if you have kidney disease, dehydration, or nerve conditions before starting. Complete the full course exactly as prescribed, even if your skin lesions improve early. Women who are pregnant or planning pregnancy should seek their doctor's advice before use.
