Common Aciclovir Problems and Quick Solutions
Treatment Not Working? Check Your Timing
The most common reason aciclovir appears ineffective is delayed treatment start. Aciclovir works best when started within 24 hours of the first tingling sensation, before blisters appear. If you're experiencing recurrent cold sores, consider keeping aciclovir tablets at home so you can begin treatment immediately. EverydayMeds offers both 400mg tablets for treatment and lower doses for suppression therapy where appropriate.
Tablet vs Cream: Choosing the Right Formulation
Many patients wonder whether aciclovir tablets or cream work better. Tablets are generally more effective for frequent outbreaks or severe symptoms, as they work systemically throughout your body. Aciclovir 5% cream is suitable for mild, infrequent cold sores and works locally on the affected area. Some patients find combining both formulations helpful, though this should be discussed with your prescriber first.
Side Effects and How to Manage Them
Common side effects include nausea, headache, and dizziness with tablets, or mild skin irritation with cream. Taking tablets with food may reduce stomach upset. If using cream causes excessive dryness, apply a thin layer and avoid overuse. Serious side effects are rare but include confusion, hallucinations, or severe skin reactions - seek immediate medical advice if these occur.
Missed Doses and Treatment Duration
If you miss an aciclovir tablet dose, take it as soon as you remember unless it's nearly time for your next dose. Never double dose. Complete the full course even if symptoms improve - typically 5 days for tablets. For cream, continue applying for at least 4 days after healing begins. Stopping treatment early may allow the virus to continue replicating.
When to Seek Further Medical Advice
Contact your healthcare provider if cold sores don't improve after completing aciclovir treatment, if you experience frequent outbreaks (more than 6 per year), or if you develop eye symptoms. Alternative treatments like valaciclovir may be more suitable for some patients. EverydayMeds stocks various antiviral options that your prescriber might recommend based on your individual needs.
