Common Side Effects of Cold Sore Treatments
Aciclovir Tablet Side Effects
Aciclovir 400mg tablets, the most commonly prescribed oral treatment for cold sores, may cause several side effects. The most frequent reactions include nausea, vomiting, diarrhea, and abdominal pain. These digestive symptoms typically occur in less than 10% of patients and often improve as your body adjusts to the medication.
Neurological Reactions
Some patients experience headaches, dizziness, or fatigue when taking oral aciclovir. These symptoms are usually mild and temporary. In rare cases, particularly in elderly patients or those with kidney problems, more serious neurological effects like confusion or tremors may occur, requiring immediate medical attention.
Skin and Allergic Reactions
Both oral and topical aciclovir treatments can cause skin reactions. Topical aciclovir cream may cause local irritation, burning, or stinging at the application site. These reactions typically subside within a few applications. Serious allergic reactions are rare but may include widespread rash, swelling of face or throat, or difficulty breathing.
Managing Treatment Side Effects
To minimise digestive upset from aciclovir tablets, take doses with food and plenty of water. If you experience mild nausea, eating small, frequent meals may help. For topical treatments causing irritation, ensure the area is clean and dry before application, and avoid touching or rubbing the treated area.
When to Seek Medical Advice
Contact your healthcare provider if you experience severe or persistent side effects, signs of allergic reaction, or if side effects worsen rather than improve. EverydayMeds offers various cold sore treatment options including aciclovir tablets, topical creams, and alternative antiviral medications like valaciclovir, allowing for treatment adjustments if needed.
Alternative Treatment Options
If aciclovir causes problematic side effects, alternatives may be suitable. Topical treatments often cause fewer systemic side effects than oral medications. Valaciclovir tablets may be better tolerated in some patients, while maintaining similar effectiveness against cold sore outbreaks.
