Aciclovir Tablet Strengths and Recommended Dosages
Standard Aciclovir Dosage for Cold Sores
Aciclovir 400mg tablets represent the most frequently prescribed strength for treating cold sore outbreaks in adults. The typical dosage involves taking one 400mg tablet three times daily for five days, ideally starting within 24 hours of symptom onset. This early intervention approach may help reduce both the severity and duration of the outbreak.
Alternative Dosage Strengths Available
Aciclovir 200mg tablets offer an alternative dosage option, typically prescribed as one tablet five times daily for the same five-day treatment period. Some healthcare providers may recommend aciclovir 400mg tablets twice daily, though this higher strength is more commonly reserved for other herpes virus infections. The choice of strength often depends on individual patient factors and medical history.
Treatment Timing and Effectiveness
Clinical studies suggest that aciclovir treatment proves most beneficial when initiated during the prodromal stage - the initial tingling, burning, or itching sensation that precedes visible blister formation. Starting treatment beyond 72 hours of symptom onset may provide limited benefit. EverydayMeds stocks aciclovir 400mg tablets alongside our aciclovir 5% cream, providing both oral and topical treatment options.
Prescription Requirements and Safety
All aciclovir tablet strengths require a valid prescription in the UK, reflecting their status as prescription-only medicines (POM). Our online consultation service connects patients with qualified prescribers who can assess suitability and recommend appropriate dosage strengths. Valaciclovir 500mg tablets and branded Valtrex represent alternative antiviral options that may be considered in specific circumstances.
