ZOVIRAX 200 MG Tablet 25s

Brand: Glaxo Smith Kline Pakistan Ltd
Active Ingredient: Acyclovir 200 mg — a well-established antiviral medicine that belongs to the purine nucleoside analogue class.

Product Description

ZOVIRAX 200 mg Tablet is an oral antiviral medication designed to treat infections caused by herpes viruses. It works by interfering with the replication of viral DNA, slowing down the spread of the virus and helping your body clear the infection more efficiently.

Acyclovir (the active ingredient) is selectively activated inside virus-infected cells, where it competes with natural nucleosides and terminates viral DNA synthesis. This targeted mechanism helps reduce the severity and duration of outbreaks while minimizing effects on healthy cells.

Therapeutic Uses

ZOVIRAX 200 mg is commonly prescribed for:

• Initial and recurrent genital herpes simplex infections

• Herpes labialis (cold sores)

• Shingles (herpes zoster)

• Chickenpox (varicella)
  Acyclovir can reduce symptoms like pain, itching, and blistering, and may shorten the duration of outbreaks when started as early as possible.

How It Works

Once absorbed, acyclovir is converted to its active triphosphate form in infected cells. This active form inhibits the viral DNA polymerase enzyme, leading to premature termination of viral DNA chains, effectively halting viral replication.

Dosage & Administration

Taken orally with or without food, as directed by a clinician. The frequency and duration depend on the type of infection, patient health status, and medical guidance. Always complete the prescribed course even if symptoms improve.

Common Side Effects

Some patients may experience:

• Nausea or vomiting

• Headache

• Dizziness

• Diarrhea

• Fatigue
  Less common or serious reactions should be reported to a healthcare provider promptly.

Precautions

Use caution in people with kidney impairment or dehydration, as dosage adjustments may be needed. Discuss pregnancy or breastfeeding with your doctor before use. Inform your clinician about other medications you are taking to avoid interactions.

Prescription Status

ZOVIRAX 200 mg requires a medical prescription and should be used under the supervision of a qualified healthcare professional.
