Understanding Aciclovir Side Effects and Solutions

Common Side Effects of Cold Sore Tablets

Aciclovir 400mg tablets, available through EverydayMeds, may cause mild side effects in some patients. The most frequently reported reactions include headaches, nausea, stomach pain, and diarrhoea. These effects typically occur within the first few days of treatment and often resolve as your body adjusts to the medication. Taking tablets with food or milk can significantly reduce stomach-related discomfort.

Managing Digestive Side Effects

If you experience nausea or stomach upset while taking aciclovir tablets, several strategies may help. Always take your medication with a meal or snack to protect your stomach lining. Staying well-hydrated throughout your treatment course is essential, particularly if you experience diarrhoea. Small, frequent meals rather than large portions can also minimise digestive discomfort. Should symptoms persist beyond 48 hours, consult your healthcare provider.

When to Seek Medical Advice

While serious side effects from cold sore tablets are uncommon, certain symptoms require immediate medical attention. Contact your doctor if you experience severe allergic reactions, including difficulty breathing, facial swelling, or widespread skin rash. Unusual bruising, persistent vomiting, or signs of kidney problems such as reduced urination should also prompt urgent medical consultation.

Alternative Treatment Options

For patients who cannot tolerate oral aciclovir, EverydayMeds offers alternative treatments including aciclovir 5% cream for topical application. Valaciclovir 500mg tablets represent another oral option that some patients find easier to tolerate. Your prescriber can discuss which treatment approach best suits your individual circumstances and medical history.
