Understanding Cold Sore Treatment Side Effects
Are Cold Sores Always Herpes?
Yes, cold sores are always caused by herpes simplex virus, typically HSV-1. This common virus affects up to 70% of the UK population, though many people never develop visible symptoms. Understanding this helps explain why antiviral treatments like aciclovir are the standard approach for managing outbreaks.
Common Side Effects of Aciclovir Treatment
Aciclovir tablets, available through EverydayMeds, may cause mild side effects in some patients. The most frequently reported reactions include nausea, headache, dizziness, and stomach discomfort. These effects are typically temporary and resolve as your body adjusts to the medication. Aciclovir 400mg tablets are generally well-tolerated when taken as prescribed.
Managing Oral Treatment Side Effects
To minimise stomach upset from aciclovir tablets, take doses with food or milk. Staying well-hydrated can help reduce headaches and support overall comfort during treatment. If nausea occurs, eating smaller, frequent meals rather than large portions may help. Alternative formulations like Valaciclovir 500mg tablets, also available through EverydayMeds, may be better tolerated by some patients.
Topical Treatment Considerations
Aciclovir 5% cream may cause temporary stinging, burning, or skin irritation at the application site. This typically subsides within minutes of application. Apply a thin layer only to affected areas and wash hands thoroughly after use. Avoid contact with eyes and mucous membranes to prevent unnecessary irritation.
When to Seek Medical Advice
Contact your healthcare provider if you experience severe side effects, signs of allergic reaction (rash, swelling, difficulty breathing), or if cold sores worsen despite treatment. EverydayMeds pharmacists can provide guidance on managing minor side effects and determining when additional medical consultation may be beneficial for your specific situation.
