Acivir 500 Injection: Complete Guide to Uses, Dosing, Side Effects & Safety

Introduction

Acivir 500 is an intravenous antiviral medication (acyclovir 500 mg) commonly used to treat serious viral infections such as shingles, herpes simplex, and chickenpox. Understanding how this injection works, how it’s administered, its benefits, potential side effects, and safety precautions is important before use. This guide provides a complete overview of this injection, helping you make informed decisions under your doctor’s care.

1. What Is Acivir 500 & How Does It Work?

Acivir 500 contains the active ingredient acyclovir, an antiviral drug that prevents the multiplication of viruses by inhibiting viral DNA replication inside infected cells. It does not cure viral infections but significantly reduces the severity, duration, and frequency of outbreaks.

Intravenous administration of this injection allows for higher concentrations of the drug in the bloodstream, making it effective for treating severe or systemic infections such as herpes encephalitis, neonatal herpes, or severe cases of varicella (chickenpox).

• Varicella zoster (chickenpox)

3. Dosage & Administration
