Understanding Aciclovir Side Effects and Solutions
Common Side Effects of Cold Sore Tablets
Aciclovir 400mg tablets, the most commonly prescribed treatment for cold sores, may cause mild side effects in some people. The most frequent reactions include headache, nausea, stomach pain, and diarrhoea. These effects typically occur during the first few days of treatment and often resolve as your body adjusts to the medication.
Taking your aciclovir tablets with food or milk can significantly reduce stomach-related side effects. Staying well-hydrated throughout your treatment course also helps minimise potential reactions and supports your recovery.
Managing Digestive Side Effects
If you experience nausea or stomach upset when taking cold sore tablets, several strategies can help. Take your medication with a light meal or snack, avoid spicy or fatty foods during treatment, and consider splitting your daily dose if your doctor agrees. EverydayMeds stocks both aciclovir tablets and valaciclovir as alternatives if one doesn't suit you.
When to Seek Medical Advice
Whilst serious side effects from aciclovir are uncommon, certain symptoms require prompt medical attention. Contact your doctor immediately if you experience severe headache, confusion, unusual bruising, or signs of kidney problems such as reduced urination. Allergic reactions, though rare, may include rash, swelling, or breathing difficulties.
Most people tolerate cold sore tablets well, but everyone responds differently to medication. If side effects persist or worsen, speak to your pharmacist or GP about alternative treatments available through EverydayMeds' range of antiviral medications.
