Zovirax 400 Mg Tablets

Zovirax 400 Mg Tablets

Description:

Zovirax 400 mg tablets are a prescription antiviral medicine containing acyclovir, used to treat and prevent infections caused by herpes viruses. It helps control herpes simplex (including genital herpes), herpes zoster (shingles), and varicella (chickenpox) by slowing the growth and spread of the virus in the body. Zovirax does not cure herpes, but it reduces the severity and duration of outbreaks, relieves symptoms, and helps prevent recurrences when used as suppressive therapy. Suitable for adults and children as directed by a physician.

Indications:

• Treatment of herpes simplex virus infections, including primary and recurrent genital herpes.
• Chronic suppressive therapy to reduce the frequency and severity of recurrent genital herpes in immunocompetent patients.
• Treatment of herpes zoster (shingles) to reduce pain, speed healing of lesions, and limit complications.
• Treatment of varicella (chickenpox) in adults and children as directed by a doctor.
• Management of certain herpes infections of the skin, eyes, nose, and mouth, including in patients with human immunodeficiency virus (HIV), as prescribed.
• Helps reduce symptoms such as pain, burning, tingling, itching, and blistering associated with herpes outbreaks.

• Use exactly as prescribed by your doctor. Do not exceed the recommended dose.
• Acute treatment of herpes zoster (shingles) – adults: 800 mg every 4 hours orally, 5 times daily for 7–10 days (typically one 800 mg dose, not the 400 mg strength; your doctor will adjust the number of 400 mg tablets accordingly).

• Treatment of chickenpox – adults and children over 40 kg: 800 mg 4 times daily for 5 days (dose to be achieved using appropriate tablet strength as prescribed).

• If you miss a dose, take it as soon as you remember unless it is almost time for the next dose. Do not double the dose to make up for a missed one.
• Duration of treatment and exact dosing schedule must always be determined by a healthcare professional based on your condition, age, kidney function, and overall health.
