Prescription Antiviral Treatments for Cold Sores
Immediate Action Steps for Cold Sore Treatment
The moment you feel that characteristic tingling sensation around your lips, it's time to act. This prodromal stage offers your best window for treatment effectiveness. Research suggests that starting antiviral therapy within 24 hours of symptom onset may help reduce outbreak duration from the typical 7-10 days to 4-6 days.
Aciclovir Tablets: First-Line Treatment
Aciclovir tablets represent the gold standard for cold sore treatment in the UK. EverydayMeds offers aciclovir 400mg tablets, which work by preventing the herpes simplex virus from replicating. The typical dosing regimen involves taking 400mg three times daily for five days, though treatment duration may vary based on individual response and severity.
Unlike topical treatments, oral aciclovir reaches higher concentrations in affected tissues and may be particularly beneficial for frequent sufferers or those experiencing severe outbreaks. The medication is generally well-tolerated, with mild side effects including occasional nausea or headache.
Alternative Antiviral Options
For patients who may benefit from alternative treatments, EverydayMeds also provides valaciclovir tablets. This medication converts to aciclovir in the body but offers improved bioavailability, meaning fewer daily doses may be required. Valaciclovir is often prescribed as 500mg twice daily for three days for episodic cold sore treatment.
Topical Treatment Considerations
While oral antivirals often provide superior results, topical aciclovir cream may be appropriate for mild outbreaks or patients preferring localised treatment. The 5% cream should be applied every four hours during waking hours, starting at the earliest signs of outbreak development.
Supporting Care Measures
Alongside antiviral therapy, several measures may help manage symptoms and prevent complications. Keeping the affected area clean and dry helps prevent secondary bacterial infection. Pain relief with paracetamol or ibuprofen can address discomfort, whilst avoiding acidic or spicy foods may prevent further irritation.
Cold sores are highly contagious, particularly during the blister and weeping stages. Avoid sharing utensils, towels, or engaging in close contact until lesions have completely healed. Frequent hand washing helps prevent virus transmission to other body areas or individuals.
