Common Side Effects and Management Strategies

Understanding Aciclovir Side Effects

Aciclovir tablets, the primary treatment for cold sores available through EverydayMeds, are generally well-tolerated. Most people experience no side effects, but some may notice mild symptoms including headaches, nausea, stomach pain, or dizziness. These effects typically occur within the first few days of treatment and usually resolve as your body adjusts to the medication.

Managing Common Side Effects

If you experience nausea or stomach upset, taking your aciclovir tablets with food or milk can help reduce digestive discomfort. For headaches, ensure you're drinking plenty of water, as dehydration can worsen this effect. If dizziness occurs, avoid driving or operating machinery until you feel better. Most mild side effects don't require stopping treatment, but contact your pharmacist if symptoms persist or worsen.

When to Seek Medical Advice

While serious side effects are uncommon, seek immediate medical attention if you experience signs of allergic reaction such as rash, swelling of face or throat, or difficulty breathing. Other concerning symptoms include severe stomach pain, unusual bleeding or bruising, or signs of kidney problems like reduced urination or swelling in legs or feet.

Alternative Treatment Options

If side effects become problematic, EverydayMeds also offers valaciclovir tablets, which some people tolerate better than aciclovir. Topical aciclovir cream provides another option with minimal systemic absorption and fewer side effects. Your pharmacist can help determine the most suitable treatment based on your individual circumstances and medical history.
