How Aciclovir Tablets Work for Cold Sores
Understanding Aciclovir Treatment
Aciclovir tablets contain an antiviral ingredient that specifically targets herpes simplex viruses. When taken orally, the medication enters your bloodstream and reaches infected cells throughout your body. The active ingredient interferes with viral DNA replication, effectively stopping the virus from multiplying and spreading to healthy cells.
When to Start Treatment
The effectiveness of aciclovir tablets largely depends on timing. Treatment should ideally begin within 24-48 hours of the first symptoms appearing - typically a tingling, burning, or itching sensation around the lip area. Starting treatment during this prodromal phase may help prevent blisters from forming or reduce their severity significantly.
Available Treatment Options
EverydayMeds stocks several antiviral options for cold sore treatment. Aciclovir 400mg tablets represent the standard first-line treatment prescribed by UK healthcare providers. For those seeking alternatives, valaciclovir 500mg tablets offer less frequent dosing schedules. Topical treatments like aciclovir 5% cream provide localised application for mild outbreaks.
Treatment Duration and Dosing
A typical course involves taking 400mg aciclovir five times daily for five consecutive days. Some individuals may require longer treatment periods, particularly during severe outbreaks. The tablets should be taken with water and can be consumed with or without food. Maintaining regular dosing intervals helps ensure consistent antiviral levels in your system.
Managing Expectations
While aciclovir tablets can significantly reduce outbreak duration and severity, they do not eliminate the herpes virus from your system permanently. The medication may help reduce healing time from 7-10 days to approximately 5-7 days when started early. Some people also use aciclovir as suppressive therapy to reduce the frequency of recurrent outbreaks.
