Common Aciclovir Treatment Issues and Solutions
Treatment Started Too Late
The most common reason aciclovir appears ineffective is delayed treatment. Aciclovir 400mg tablets work best when started within 24-48 hours of first symptoms (tingling, burning sensation). If treatment begins after blisters have fully formed, the medication may only slightly reduce healing time. For future outbreaks, keep aciclovir tablets readily available and start treatment immediately when you notice early warning signs.
Insufficient Dosage or Duration
Standard aciclovir dosing for cold sores is typically 400mg five times daily for 5 days. Taking fewer doses or stopping treatment early may result in prolonged symptoms. EverydayMeds provides clear dosage instructions with all aciclovir prescriptions. If you're using aciclovir 5% cream, apply it five times daily, ensuring complete coverage of the affected area. Some patients may require valaciclovir 500mg tablets as an alternative with more convenient twice-daily dosing.
Switching Between Treatment Forms
If topical aciclovir cream isn't providing adequate relief, oral tablets may be more effective. Aciclovir tablets work systemically, potentially offering better results for severe or frequent outbreaks. Conversely, if tablets cause unwanted side effects, topical treatment might be preferable. EverydayMeds stocks both formulations, allowing you to find the most suitable option through consultation with our pharmacists.
Managing Side Effects
Common aciclovir side effects include nausea, headache, or skin irritation with topical use. Taking tablets with food may reduce stomach upset. If side effects persist, valaciclovir tablets often cause fewer gastrointestinal issues whilst providing similar antiviral effectiveness. Severe side effects are rare but require immediate medical attention.
Preventing Future Outbreaks
If you experience frequent cold sores (more than 6 per year), suppressive therapy with daily aciclovir may be recommended. This involves taking lower doses continuously to prevent outbreaks rather than treating them as they occur. EverydayMeds can arrange consultations to discuss long-term management strategies and ensure you have appropriate treatments available when needed.
