Zovirax Suspension contains Acyclovir 400 mg, an antiviral medication indicated for the treatment of infections caused by herpes simplex virus types 1 and 2, including orolabial and genital herpes, as well as varicella-zoster virus responsible for chickenpox and shingles. Acyclovir acts by inhibiting viral DNA synthesis, thereby limiting viral replication and spread within the host. This suspension formulation is particularly suitable for pediatric patients or individuals who have difficulty swallowing tablets. Zovirax Suspension is administered orally, with dosage and duration tailored according to the severity and location of the infection, patient age, and renal function. Common adverse effects are generally mild and may include gastrointestinal disturbances such as nausea, vomiting, and diarrhea, as well as headache and dizziness. Patients with known hypersensitivity to acyclovir or any component of the formulation should avoid use. Adequate hydration is recommended during therapy to reduce the risk of renal toxicity. Zovirax Suspension should be used under medical supervision, especially in immunocompromised patients, to ensure optimal therapeutic outcomes and monitor for potential adverse reactions. It is important to complete the full prescribed course to prevent viral resistance and recurrence.
