Got that tingling on your lip again? The faster you act, the shorter a cold sore usually lasts. This page breaks down the medicines people actually use—what helps, how to apply them, and when to talk to a clinician. No jargon, just plain practical info so you can choose a smart next step.
There are two main approaches: topical (creams applied to the sore) and oral (pills that treat the virus systemically).
Topical options: Docosanol (OTC, sold as Abreva) is one widely used over-the-counter choice—start at the first sign (tingle or redness) and apply as directed, usually up to five times a day until healed. Topical acyclovir creams also exist and can shorten healing when used early.
Oral antivirals: These work best when started at the first symptom. Common prescription choices are valacyclovir, famciclovir, and oral acyclovir. Short courses can stop a blister from forming or speed recovery. For example, doctors often give single-day or short multi-day regimens for recurrent cold sores—but follow your prescriber's instructions before trying any dose on your own.
Suppressive therapy: If you get frequent outbreaks, daily antiviral pills can reduce how often they come. That’s a conversation to have with your doctor—especially if outbreaks affect your work or confidence.
Antivirals are generally well tolerated. Common side effects are mild—headache, nausea, or stomach upset. If you have kidney disease or take other medicines, doses may need adjusting. Pregnant or breastfeeding? Tell your provider before starting anything.
Never use someone else’s prescription. If you’re buying online, pick a licensed pharmacy that asks for a prescription when required, shows real contact info, and has clear shipping and return policies. Look for reviews and pharmacist access—those are good signs.
When to see a doctor now: if sores spread to your eyes, you’re immunocompromised, the outbreak is very painful, or you have a fever and more severe symptoms. Also seek care if you get blisters often—there are prevention options.
Practical tips: start treatment at the first tingle, keep the area clean and avoid touching the sore, wash hands often to prevent spread, and avoid kissing or sharing utensils while blisters are active. Lip balm with SPF helps; sun exposure can trigger outbreaks for some people.
