Overview

Sunward Zorax Suspension contains acyclovir, an antiviral medicine used to treat infections caused by herpes simplex virus (such as cold sores and genital herpes) and varicella-zoster virus (chickenpox and shingles). The suspension form is particularly suitable for children or patients who have difficulty swallowing tablets.

Acyclovir is converted inside virus-infected cells into its active form, which blocks the viral DNA polymerase enzyme, an enzyme the virus needs to copy its genetic material. This stops the virus from multiplying, helping to control the infection and relieve symptoms.

How it Works

Acyclovir is selectively activated inside cells infected by herpes viruses, where it is converted into a form that blocks viral DNA polymerase, halting viral DNA replication and stopping the virus from spreading to new cells.

Directions for Use

Shake Sunward Zorax Suspension well before use and measure the dose accurately with the measuring device provided. Start treatment as early as possible after symptoms appear for the best results, and complete the full course even if symptoms improve before it ends.

Dosage

Dosing is based on age, body weight, and the specific infection being treated, and is usually given multiple times daily for 5-10 days. Your doctor will confirm the exact dose and duration, especially for children.
