Aciclovir Dosage and Administration Guidelines

Standard Dosing for Cold Sores

The typical prescription for cold sore treatment involves aciclovir 400mg tablets taken five times daily for five days. Your healthcare provider may adjust this based on your individual circumstances. EverydayMeds stocks aciclovir 400mg tablets, which represent the most commonly prescribed strength for cold sore management. Some patients may be prescribed 200mg tablets with different dosing schedules.

When to Start Treatment

Aciclovir works most effectively when started at the first sign of a cold sore outbreak. This includes the initial tingling, burning, or itching sensation that often occurs before blisters appear. Starting treatment within 24 hours of symptom onset may provide the best outcomes. If you frequently experience cold sores, your doctor might prescribe aciclovir to keep on hand for immediate use when symptoms begin.

How to Take Aciclovir Tablets

Swallow aciclovir tablets whole with a full glass of water. The medication can be taken with or without food, though taking it with food may help reduce potential stomach upset. Space doses evenly throughout the day, approximately every 4-6 hours while awake. Maintain good hydration by drinking plenty of fluids during treatment, as this supports kidney function whilst processing the medication.

Treatment Duration and Compliance

Complete the full five-day course of treatment even if your cold sore symptoms improve earlier. Stopping treatment prematurely may allow the virus to continue replicating, potentially prolonging the outbreak. If you miss a dose, take it as soon as you remember, unless it's nearly time for your next dose. Never double up on doses to catch up.

Alternative Aciclovir Formulations

EverydayMeds also provides valaciclovir tablets and aciclovir cream as alternative treatment options. Valaciclovir is converted to aciclovir in the body and may offer more convenient dosing schedules. Topical aciclovir cream can be used alongside tablets or as standalone treatment for mild outbreaks. Your healthcare provider can advise which option might be most suitable for your needs.
