Aciclovir Dosage and Administration Guidelines
When to Start Taking Aciclovir
The timing of aciclovir treatment is crucial for effectiveness. Begin treatment at the first sign of a cold sore outbreak, ideally during the initial tingling or burning sensation. Starting aciclovir within 24-48 hours of symptom onset may help reduce the severity and duration of the outbreak. If you frequently experience cold sores, your doctor may prescribe aciclovir to keep on hand for immediate use when symptoms begin.
Aciclovir Tablet Dosage
For cold sores, the standard aciclovir tablet dosage is typically 200mg taken five times daily at approximately four-hour intervals. Treatment usually continues for five days, though your doctor may adjust this based on your individual circumstances. The 400mg tablets may be prescribed as 400mg three times daily as an alternative regimen. Take tablets with a full glass of water, and they can be taken with or without food. Maintain regular dosing intervals throughout the day, including during waking hours.
Aciclovir Cream Application
Aciclovir 5% cream should be applied to the affected area every four hours, approximately five times per day. Apply a thin layer to the cold sore and surrounding area, gently rubbing it in until absorbed. Wash your hands thoroughly before and after application to prevent spreading the infection. Continue treatment for five days, or until the lesion has healed. EverydayMeds stocks both aciclovir tablets and cream formulations for comprehensive cold sore management.
Important Safety Considerations
Always complete the full prescribed course, even if symptoms improve before finishing the medication. Drink plenty of fluids while taking aciclovir tablets to stay well-hydrated. If you miss a dose, take it as soon as you remember, but avoid doubling doses if it's nearly time for the next one. Store aciclovir at room temperature away from moisture and heat. Contact your healthcare provider if symptoms worsen or don't improve after completing the course, or if you experience any concerning side effects.
