Zovirax Uses, Dosage, Side Effects & Price in Pakistan

1. Quick Info (Mukhtasir Maloomat)

2. What is Zovirax? (Zovirax kya hai)

Zovirax belongs to the antiviral drug class and contains acyclovir as its active ingredient. Acyclovir works by interfering with the way certain viruses, mainly the herpes simplex virus and the varicella-zoster virus, copy their genetic material. By blocking this copying process inside infected cells, it slows the spread of the virus in the body, allowing the immune system to bring the infection under control more effectively. Zovirax is typically prescribed for adults and, in some cases, children who have been diagnosed with a herpes-related viral infection by a doctor.

Within the antiviral class, Zovirax is one of several acyclovir-based options available to prescribers, alongside other formulations and related antiviral agents used for similar viral infections. The exact medicine, strength, and treatment course a patient needs depends on the specific condition, its severity, and individual health factors such as kidney function. Always take Zovirax as directed by your doctor or pharmacist.
