Understanding Aciclovir Tablet Side Effects

Common Side Effects of Aciclovir Tablets

Most patients taking aciclovir tablets experience few or no side effects. When side effects do occur, they are typically mild and resolve quickly. Common side effects may include nausea, headache, dizziness, vomiting, diarrhoea, and stomach pain. These effects usually improve as your body adjusts to the medication and rarely require treatment discontinuation.

When to Seek Medical Advice

While serious side effects are uncommon, certain symptoms require prompt medical attention. Contact your healthcare provider immediately if you experience signs of allergic reaction such as rash, itching, swelling of face or throat, or difficulty breathing. Additionally, seek medical advice if you develop unusual bruising, yellowing of skin or eyes, confusion, or signs of kidney problems including reduced urination or swelling.

Managing Side Effects Effectively

Taking aciclovir tablets with food can help reduce stomach upset and nausea. Staying well-hydrated throughout treatment supports kidney function and may minimise certain side effects. If you experience headaches, ensure adequate rest and consider discussing pain relief options with your pharmacist.
