Common Aciclovir Side Effects and Management

Understanding Aciclovir Tablet Side Effects

Aciclovir tablets, including the 400mg formulation available through EverydayMeds, are generally well-tolerated antiviral medications. However, like all medicines, they can cause side effects in some people. Most reactions are mild and resolve without intervention, but understanding potential effects helps you manage treatment more confidently.

Most Common Side Effects

The most frequently reported side effects include headaches, nausea, dizziness, and stomach upset. These typically occur in fewer than 1 in 10 people taking aciclovir tablets. Headaches often respond well to paracetamol and staying well-hydrated. If you experience nausea, taking your aciclovir tablets with food or milk can help reduce stomach irritation.

Managing Digestive Side Effects

Some people may experience stomach pain, diarrhoea, or feeling sick when taking aciclovir. To minimise these effects, avoid taking tablets on an empty stomach. Eating a light snack or meal before your dose can significantly reduce digestive discomfort. If diarrhoea occurs, maintain fluid intake and consider probiotics to support gut health recovery.

When to Seek Medical Advice

While serious side effects are rare, certain symptoms require prompt medical attention. Contact your healthcare provider if you experience severe skin reactions, difficulty breathing, unusual bruising, or persistent vomiting. EverydayMeds recommends keeping a symptom diary to track any patterns or concerns during treatment.

Optimising Your Treatment Experience

To minimise side effects, take aciclovir exactly as prescribed, complete the full course even if symptoms improve, and maintain good hydration. The 400mg tablets available through EverydayMeds should be taken at evenly spaced intervals as directed. Never exceed the recommended dose, as this increases side effect risk without improving effectiveness.
