Comparing Cold Sore Treatment Options
Prescription Antiviral Tablets
Aciclovir 400mg tablets represent the most commonly prescribed oral treatment for cold sores. These work by stopping the herpes simplex virus from reproducing, potentially reducing outbreak duration from 7-10 days to 4-6 days when started early. The standard dose involves taking 400mg three times daily for five days.
Valaciclovir offers an alternative with more convenient dosing - typically 500mg twice daily for five days. This medication converts to aciclovir in the body but achieves higher blood levels, potentially offering superior effectiveness. However, valaciclovir usually costs more than standard aciclovir tablets.
Topical Antiviral Treatments
Aciclovir 5% cream provides localised treatment applied directly to cold sores. While convenient and available without prescription, topical treatments generally show less dramatic effects than oral medications. The cream should be applied five times daily, starting at the first tingling sensation.
Topical treatments may suit those who prefer avoiding systemic medication or experience side effects from tablets. However, application can be messy, and the cream may not penetrate deeply enough for optimal effectiveness.
Treatment Timing Considerations
All cold sore medications work best when started during the prodromal phase - the initial tingling or burning sensation before blisters appear. Starting treatment after blisters have formed significantly reduces effectiveness for any medication type.
For people experiencing frequent outbreaks (more than six per year), doctors sometimes prescribe suppressive therapy using daily low-dose aciclovir. This approach can reduce outbreak frequency by up to 80% in suitable candidates.
Cost and Value Comparison
Generic aciclovir tablets typically offer the most cost-effective option for cold sore treatment. Brand names like Zovirax contain identical active ingredients but cost significantly more. Most patients achieve equivalent results with generic versions available through online pharmacies.
Valaciclovir costs more than aciclovir but requires fewer daily doses, which some people find more convenient. The choice often depends on individual preferences regarding dosing frequency versus cost considerations.
