Common Aciclovir Treatment Issues and Solutions
Why Isn't My Aciclovir Working?
The most common reason aciclovir appears ineffective is delayed treatment initiation. Aciclovir works best when started within 24-48 hours of the first symptoms - typically the tingling or burning sensation before blisters appear. If treatment begins after blisters have fully formed, the medication may still help reduce healing time but won't prevent the outbreak.
Proper Aciclovir Dosing and Timing
For aciclovir 400mg tablets, the standard dose is one tablet five times daily for five days. This means taking tablets approximately every 4 hours during waking hours. Missing doses can significantly reduce effectiveness. EverydayMeds stocks aciclovir 400mg tablets, the most commonly prescribed strength for cold sore treatment. Some patients may also benefit from valaciclovir 500mg tablets, which require less frequent dosing.
Cream vs Tablet Effectiveness
Many patients ask whether aciclovir cream or tablets work better. Tablets generally provide superior results for frequent outbreaks as they work systemically throughout the body. Aciclovir 5% cream may be preferred for mild, infrequent cold sores or when tablets aren't suitable. The cream should be applied every 4 hours, starting at the first sign of symptoms.
Managing Side Effects
Common aciclovir side effects include nausea, headache, and dizziness. Taking tablets with food often reduces stomach upset. Drinking plenty of water helps prevent kidney-related side effects, particularly important with higher doses. If you experience severe side effects, consult your healthcare provider about alternative treatments like valaciclovir.
When to Seek Medical Advice
Contact your doctor if cold sores don't begin healing within 5 days of treatment, if you develop more than 6 outbreaks yearly, or if you experience severe side effects. Frequent outbreaks may require suppressive therapy with daily aciclovir. EverydayMeds offers various antiviral options including branded treatments for those who may respond differently to generic formulations.
