Understanding Aciclovir Side Effects
Common Side Effects of Cold Sore Tablets
Aciclovir tablets, the most frequently prescribed antiviral for cold sores, may cause several mild side effects. The most common include nausea, headache, dizziness, and stomach upset. These reactions typically occur in fewer than 1 in 10 patients and often resolve as your body adjusts to the medication. Valaciclovir tablets, an alternative antiviral available through EverydayMeds, may cause similar effects but are often better tolerated due to improved absorption.
Reducing Digestive Side Effects
Taking cold sore tablets with food significantly reduces the likelihood of nausea and stomach upset. Choose plain foods like toast or crackers if you're feeling queasy. Avoiding spicy or fatty foods during treatment may also help. If nausea persists, speak with your EverydayMeds pharmacist about timing adjustments or alternative formulations that might suit you better.
Managing Headaches and Dizziness
Staying well-hydrated helps prevent headaches associated with antiviral treatment. Aim for at least 8 glasses of water daily whilst taking aciclovir or valaciclovir. If dizziness occurs, avoid sudden position changes and ensure adequate rest. These symptoms typically improve within 24-48 hours as your body adapts to the medication.
When to Seek Advice
Contact your pharmacist if side effects worsen or persist beyond the first few days of treatment. Rare but serious reactions include severe headache, confusion, or unusual bruising. EverydayMeds pharmacists can assess whether continuing treatment is appropriate or if switching to topical aciclovir cream might be preferable for managing your cold sore outbreak.
Alternative Treatment Options
If oral antivirals cause troublesome side effects, topical treatments like aciclovir cream 5% offer effective alternatives with minimal systemic absorption. EverydayMeds stocks both prescription tablets and over-the-counter creams, allowing flexible treatment approaches based on your individual tolerance and outbreak severity.
