Quick Reference: Aciclovir Dosing & Administration
How Aciclovir Works for Cold Sores
Aciclovir is an antiviral medication that targets the herpes simplex virus (HSV-1) responsible for cold sores. It works by interfering with the virus's ability to reproduce, potentially reducing the severity and duration of outbreaks when treatment begins early. The medication is most effective when started within 24-48 hours of the first symptoms appearing.
Standard Dosing Guidelines
For cold sore treatment, aciclovir 400mg tablets are typically prescribed at a dose of one tablet five times daily for five days. Treatment should begin as soon as possible after symptoms start - ideally at the first tingling sensation. EverydayMeds stocks aciclovir 400mg tablets specifically for this indication, alongside topical aciclovir 5% cream for localised application.
Tablet vs Cream Application
Aciclovir tablets work systemically throughout the body, whilst topical cream provides localised treatment directly to the affected area. Many patients find tablets more convenient, particularly for frequent outbreaks. The cream should be applied every 4 hours during waking hours, using a clean finger or cotton swab to avoid spreading the infection.
Treatment Timeline Expectations
With prompt treatment, aciclovir may help reduce cold sore healing time from the typical 7-10 days to approximately 5-7 days. Early intervention during the tingling stage often provides the best outcomes. Even if blisters have already formed, starting treatment can still be beneficial for managing symptoms and potentially reducing viral shedding.
Available Treatment Options
EverydayMeds offers several aciclovir formulations including 400mg tablets for oral treatment and topical preparations. For patients who experience frequent outbreaks, valaciclovir 500mg tablets provide an alternative antiviral option with less frequent dosing requirements. Our online consultation service ensures appropriate prescribing based on individual circumstances and medical history.
