Indications for Use

Zovirax 400 mg is indicated for various conditions, including:

  1. Herpes Simplex Virus Infections

Mechanism of Action

The active ingredient in Zovirax, acyclovir, works by mimicking the structure of a nucleoside. This allows it to be incorporated into the viral DNA during replication, effectively terminating the process. The result is a decreased ability of the virus to multiply, which helps the body fight off the infection.

Patients are advised to follow their healthcare provider’s instructions regarding dosage. The typical regimen for Zovirax 400 mg is:

  1. For Herpes Simplex: 5 times a day for 5 days.
  2. For Shingles: 5 times a day for 7 days.
  3. For Chickenpox: 4 times a day for 5 days.

It is crucial to maintain proper hydration while taking this medication to prevent complications.

  1. Nausea or Vomiting
  2. Diarrhea
  3. Headache
  4. Fatigue
  5. Itching or Rash

With its well-established mechanism of action and guidelines for proper usage, patients can effectively manage their condition under the supervision of healthcare professionals.
