Common Side Effects and Practical Management Tips
Understanding Aciclovir Side Effects
Aciclovir tablets may cause side effects in some patients, though many people tolerate the medication well. Common side effects include nausea, headache, dizziness, and stomach upset. These typically occur within the first few days of treatment and often improve as your body adjusts to the medication.
Gastrointestinal Side Effects Management
Nausea and stomach discomfort are among the most frequently reported side effects. Taking aciclovir tablets with food or milk can significantly reduce these symptoms. Eating small, frequent meals rather than large portions may also help. If vomiting occurs, ensure you stay hydrated and contact your pharmacist for advice on continuing treatment. Avoiding spicy or fatty foods during treatment may further minimise digestive upset.
Managing Headaches and Dizziness
Headaches affect some patients taking aciclovir tablets and may be related to dehydration. Drinking plenty of water throughout your treatment can help prevent this side effect. Paracetamol may be used for headache relief, but consult your pharmacist before combining medications. If dizziness occurs, avoid driving or operating machinery until symptoms resolve. Getting up slowly from sitting or lying positions can help prevent dizzy spells.
When to Seek Medical Advice
Most aciclovir side effects are mild and manageable, but certain symptoms require immediate medical attention. Contact your healthcare provider if you experience severe abdominal pain, signs of kidney problems such as reduced urination or blood in urine, or allergic reactions including rash, swelling, or difficulty breathing. Persistent or worsening side effects that don't improve after 2-3 days should also be discussed with your pharmacist or GP.
