Common Side Effects and Management Strategies
Understanding Cold Sore Tablet Side Effects
Aciclovir tablets and other antiviral medications for cold sores can cause side effects, though most people tolerate them well. The most frequently reported side effects include headaches, nausea, dizziness, and stomach upset. These typically occur in less than 10% of patients and are usually mild.
Managing Common Side Effects
Headaches are among the most common complaints with aciclovir treatment. Taking paracetamol or ibuprofen may help, provided there are no contraindications. Ensuring adequate hydration is particularly important as dehydration can worsen headaches and potentially affect kidney function.
Nausea and stomach upset can often be minimised by taking tablets with food or milk. If symptoms persist, smaller, more frequent doses throughout the day might be better tolerated than larger single doses, though this should be discussed with your prescriber first.
Hydration and Kidney Function
Antiviral medications can occasionally affect kidney function, particularly in elderly patients or those with existing kidney problems. Drinking plenty of water throughout treatment helps support kidney function and reduces the risk of complications. Aim for at least 8 glasses of water daily unless advised otherwise by your doctor.
Recognising Serious Side Effects
While rare, some side effects require immediate medical attention. Signs of allergic reactions include rash, swelling of face or throat, and difficulty breathing. Unusual bruising, severe headaches, or changes in vision should also prompt urgent medical review.
