Common Side Effects and Management Strategies

Understanding Aciclovir Side Effects

Aciclovir tablets, the primary treatment for cold sores available through EverydayMeds, may cause side effects in some patients. Common reactions include headache, nausea, dizziness, and stomach discomfort. These effects typically occur as your body adjusts to the antiviral medication and often improve within a few days of starting treatment.

Immediate Management Steps

If you experience nausea or stomach upset, take your aciclovir tablets with food or milk to reduce irritation. Staying well-hydrated can help minimise headaches and support your body's processing of the medication. For dizziness, avoid sudden movements and sit down if you feel unsteady. These strategies work equally well with alternative treatments like valaciclovir tablets.

When to Seek Medical Advice

While most side effects are manageable, certain symptoms require prompt medical attention. Contact your healthcare provider if you experience severe nausea preventing you from keeping fluids down, persistent headaches, unusual bruising, or signs of allergic reaction such as rash or breathing difficulties. EverydayMeds' consultation service can help assess whether your symptoms warrant immediate medical review.

Long-term Considerations

Patients on repeat cold sore treatment should monitor for any changes in side effect patterns. Regular kidney function monitoring may be recommended for long-term use. Consider discussing alternative options like aciclovir cream for localised treatment if oral tablets consistently cause troublesome effects. Always complete your prescribed course unless advised otherwise by a healthcare professional.
