Anbesol Cold Sore Therapy is a maximum-strength over-the-counter topical ointment manufactured by Haleon US Services (formerly GlaxoSmithKline Consumer Healthcare). It has been marketed since 2006 and is specifically formulated to treat the pain, dryness, and discomfort of fever blisters and cold sores caused by the herpes simplex virus (HSV-1).
The product contains four active ingredients: benzocaine 20% (local anesthetic for fast pain numbing), camphor 3% (counter-irritant providing cooling sensation), allantoin 1% (skin protectant that promotes cell renewal and softens the lesion), and white petrolatum 64.9% (occlusive skin protectant that creates a moisture-sealing barrier over the sore). It also includes vitamin E and aloe extract as inactive ingredients.
Anbesol Cold Sore Therapy does not have antiviral properties and does not shorten the duration of a cold sore outbreak or prevent recurrence. It provides symptomatic relief and protects the lesion while it heals over its natural 7–10 day course.
We have a 99% success rate finding medications, even during nationwide shortages.

Anbesol Cold Sore Therapy works through four complementary mechanisms, each targeting a different aspect of the cold sore experience. Benzocaine (20%) blocks voltage-gated sodium channels in peripheral nerve endings, preventing pain signal transmission to the brain — providing temporary but fast-acting numbing relief within 30–60 seconds of application.
Camphor (3%) activates TRPM8 cold receptors in the skin, creating a cooling sensation that reduces itching and burning. Allantoin (1%) stimulates keratinocyte proliferation (new skin cell growth) and softens the hardened crust of the lesion through mild keratolytic action. White petrolatum (64.9%) forms a thick occlusive barrier over the cold sore, locking in moisture, protecting exposed tissue from environmental irritants, and keeping the active ingredients in contact with the skin longer.
The numbing effect of benzocaine typically lasts 15–30 minutes per application, which is why the product is used up to 3–4 times per day to maintain comfort throughout the day. Anbesol Cold Sore Therapy does not contain any antiviral agents and cannot reduce the duration of the herpes simplex virus outbreak.

As of 2026, there is no FDA-declared national shortage of Anbesol Cold Sore Therapy. The product remains in active production and distribution by Haleon US Services nationally. However, localized stockouts at individual pharmacy locations are common and are frequently reported by patients. These occur due to seasonal demand spikes (cold sores peak in winter and summer), lean pharmacy inventory management, and the product's niche status meaning individual locations stock very few units at a time.
The product is generally stocked at major chain pharmacies (CVS, Walgreens, Walmart, Target, Kroger) but not always at smaller independent pharmacies. Online availability through Amazon and pharmacy websites is typically reliable. A findability score of 78/100 reflects that the product is generally available but patients may need to check multiple locations during peak seasons.
If your local pharmacy is out of stock, use medfinder to have pharmacies near you called to check current availability — you'll receive a text with which pharmacies have it in stock. You can also check CVS.com, Walgreens.com, and Walmart.com for real-time in-store availability by zip code.
Anbesol Cold Sore Therapy is an OTC product — no prescription is required. Any adult can purchase it without seeing a healthcare provider. However, healthcare providers play an important role in recommending this product and counseling patients on appropriate use, particularly regarding the benzocaine methemoglobinemia warning and contraindications.
Providers who commonly counsel patients on Anbesol Cold Sore Therapy and cold sore management include:
For patients who need prescription antiviral treatment (valacyclovir, acyclovir, famciclovir) for recurrent or severe cold sores, prescriptions can be obtained from PCPs, NPs, PAs, dermatologists, and telehealth platforms including Teladoc, MDLive, Hims, Hers, and Wisp. Telehealth is especially convenient for getting a same-day prescription when treatment is needed at the first sign of an outbreak.
No. Anbesol Cold Sore Therapy is not a controlled substance and is not scheduled by the DEA. It is an over-the-counter (OTC) product that can be purchased without a prescription at pharmacies and retail stores. No DEA registration, prescription, or special authorization is required to dispense or purchase it.
Anbesol Cold Sore Therapy is regulated under the FDA's OTC drug monograph system for topical anesthetics and skin protectants. Adults and children 2 years and older can use it without medical supervision, though adult supervision is recommended for children under 12. The product is contraindicated in children under 2 years of age due to the benzocaine-related methemoglobinemia risk.
Most users experience only the expected effects and minimal side effects when using Anbesol Cold Sore Therapy as directed. Common mild effects include:

Abreva (docosanol 10%)
The only FDA-approved OTC product proven to shorten cold sore healing time. Apply 5x/day at first sign of outbreak. Does not provide pain numbing — focuses on antiviral action. ~$18–$22 retail.
Orajel Cold Sore Treatment
Benzocaine 5% + benzalkonium chloride 0.13% in a touch-free applicator. Lower benzocaine concentration than Anbesol but similar pain-relief mechanism. Widely available.
Carmex Cold Sore Treatment
Contains benzocaine, camphor, and menthol. Very widely available including at gas stations and convenience stores — good emergency backup when pharmacies are out.
Compeed Cold Sore Patches
Hydrocolloid gel patches that create a moist healing environment and reduce visibility of the sore. No chemical anesthetic — good for discretion and protection rather than pain relief.
Valacyclovir (Valtrex)
Prescription antiviral. 2g BID x 1 day (episodic) or 500mg/day (suppressive). Highly effective at shortening healing time and reducing outbreak frequency. Generic is widely affordable.

Dapsone
majorAdditive methemoglobinemia risk. Dapsone is one of the most common drugs associated with methemoglobinemia; concurrent benzocaine use may significantly increase risk. Consult physician before use.
Nitrates (nitroglycerin, isosorbide)
moderateBoth nitrates and benzocaine can increase methemoglobin levels; concurrent use may have additive effect on methemoglobinemia risk, particularly in susceptible patients.
Sulfonamide antibiotics (trimethoprim-sulfamethoxazole)
moderateSulfonamides can cause methemoglobinemia, especially in G6PD-deficient patients; additive risk with benzocaine-containing products.
Primaquine
moderateAntimalarial with significant methemoglobinemia risk, especially in G6PD deficiency; additive risk with topical benzocaine.
Other local anesthetics (lidocaine, prilocaine)
minorConcurrent application of multiple local anesthetics increases total methemoglobinemia burden; minimize overlapping use.
Anbesol Cold Sore Therapy is an effective, widely trusted OTC option for managing the pain and discomfort of cold sores and fever blisters. Its four-ingredient formula — combining a high-concentration local anesthetic (benzocaine 20%), a counter-irritant (camphor 3%), a skin-healing agent (allantoin 1%), and a protective moisture barrier (white petrolatum 64.9%) — provides comprehensive symptomatic coverage that most single-ingredient products cannot match.
The key limitation is that it does not have antiviral properties and does not shorten the duration of the outbreak. For patients who want to speed healing, Abreva (docosanol 10%) is the only FDA-approved OTC antiviral. For patients with frequent recurrences, prescription antivirals offer superior clinical benefit and may be more cost-effective over time.
