Zovirax (Acyclovir) Buyer and Patient Handbook in South Africa

What is Zovirax?

Zovirax is a brand-name antiviral medication whose active ingredient is acyclovir. It belongs to the nucleoside-analogue class and is used to treat infections caused by herpes viruses, including genital herpes, oral herpes (Cold Sores), and shingles (Herpes Zoster). In South Africa, Zovirax tablets are approved by the South African Health Products Regulatory Authority (SAHPRA) and comply with international quality standards. The product is supplied as oral tablets that come in strengths of 200 mg, 400 mg, and 800 mg.

Who Should Use Zovirax?

• Adults and adolescents (≥12 years) with confirmed Herpes Simplex or Varicella-Zoster infections
• Individuals experiencing recurrent cold sores who need episodic therapy
• Patients requiring a short-course treatment for genital herpes outbreaks
• People whose immune systems are competent enough to clear the infection without intravenous therapy

How Does It Work?

Acyclovir mimics the building blocks of viral DNA. When the herpes virus replicates, it incorporates acyclovir into its DNA chain, causing premature termination and preventing the virus from multiplying. Think of it as a faulty brick that stops a wall from being completed. By limiting viral replication, symptoms improve faster and the risk of spreading the infection is reduced. Zovirax carries low abuse potential and is not habit-forming.

Why Choose Zovirax?

• Proven efficacy: Clinical trials have shown that acyclovir shortens the duration of herpes lesions by 1-2 days compared with no treatment.
• Convenient oral form: Tablets are easy to store and take, without the need for injections.
• Brand consistency: Zovirax offers strict batch-to-batch quality control, while generic acyclovir is also available at a lower cost if price is a primary concern.
• Off-label uses (such as prevention of cytomegalovirus in transplant patients) should only be considered after discussion with a qualified health-care professional.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

*Exact dosing may vary according to the infection type and patient characteristics; follow the prescribing information or health-care professional advice.

How to Take

• Swallow each tablet whole with a full glass of water.
• Doses are best spaced evenly (e.g., every 4 hours) to maintain steady drug levels.
• Food does not significantly affect absorption, so tablets can be taken with or without meals.

Missed Dose

If a dose is missed and the next scheduled dose is more than 2 hours away, take the missed tablet as soon as you remember. Skip the missed dose if it is almost time for the next one; do not double-dose.

Overdose

Symptoms of overdose may include nausea, vomiting, dizziness, or confusion. Seek immediate medical attention at the nearest hospital or call emergency services. Provide details of the amount taken and the time of ingestion.

Special Populations

• Elderly (≥65 years): No dose reduction is required if renal function is normal, but monitor kidney markers.
• Renal impairment: Reduce dose proportionally to glomerular filtration rate (e.g., 50 % reduction for CrCl < 30 mL/min).
• Pregnancy & lactation: Acyclovir is classified as Category B3 in South Africa; it may be used when the benefit outweighs the risk, but discuss with a health-care professional.
• Children: Zovirax tablets are not recommended for children under 12 years; liquid formulations of acyclovir are used instead.

Lifestyle & Diet

• Hydration: Drink plenty of water to help the kidneys clear the drug.
• Grapefruit: No known interaction, but maintain a balanced diet.
• Alcohol: Moderate consumption does not affect acyclovir, but excessive drinking may impair immune response.
• Sun exposure: During shingles treatment, protect the rash area from direct sunlight to avoid irritation.

Precautions and Warnings

• Assess renal function before initiating therapy, especially in patients with chronic kidney disease.
• Use with caution in immunocompromised individuals; they may require a longer treatment course.
• Discontinue Zovirax if a severe skin reaction (e.g., Stevens-Johnson syndrome) develops and seek urgent care.
• Do not use Zovirax for viral infections other than those listed without professional guidance.
