About Amlexanox

Indications of Amlexanox

Amlexanox (as a 5% oromucosal paste) is an FDA-approved, evidence-based topical treatment with the following indications:

Established/FDA-approved use

  • Recurrent aphthous ulcers (canker sores): Amlexanox oral paste is indicated for the treatment of aphthous ulcers (canker sores) of the mouth in patients with a normal immune system, to reduce ulcer pain and speed healing when applied at the first sign of an ulcer.

Historical/regional off-label use

  • In some countries, an oral tablet form of Amlexanox has historically been used as an adjunct anti-allergic/anti-inflammatory agent for bronchial asthma and allergic conditions such as allergic rhinitis; this tablet formulation is not the standard, FDA-approved use and is not widely available or established in most markets, including Bangladesh, where the topical oral paste is the marketed form.

Amlexanox paste is not intended for ulcers caused by other conditions (e.g., herpes, trauma, systemic disease); a physician should evaluate ulcers that are unusually large, persistent, or recurrent.

Frequently Asked Questions about Amlexanox

What is Amlexanox oral paste used for?

Amlexanox oral paste is used to treat aphthous ulcers, commonly known as canker sores, inside the mouth. Applying Amlexanox at the first sign of an ulcer can help reduce pain and speed up healing.

How do I apply Amlexanox paste correctly?

Gently dry the ulcer with a clean tissue, then use a clean fingertip or cotton swab to apply a small (about 1/4-inch) dab of Amlexanox paste directly onto the ulcer, 4 times a day (after meals and at bedtime), without rubbing it in. Wash your hands before and after application.

Can I use Amlexanox during pregnancy or while breastfeeding?

Data on Amlexanox use in pregnancy and breastfeeding are limited. Amlexanox should be used during pregnancy or lactation only if clearly needed, and only after discussing the potential benefits and risks with your physician.

What are the common side effects of Amlexanox?

The most common side effect of Amlexanox is a mild, transient stinging or burning sensation at the application site, occurring in about 1-2% of users. Less commonly, local irritation, nausea, or diarrhea may occur. Serious allergic reactions are rare but require immediate discontinuation of Amlexanox and medical attention.

Who should not use Amlexanox?

Amlexanox should not be used by anyone with a known hypersensitivity (allergy) to Amlexanox or to any other ingredient in the paste. This is the only true absolute contraindication.

What should I do if my ulcer does not heal after using Amlexanox?

If your ulcer has not healed within 10 days of starting Amlexanox, or if it becomes unusually severe, large, or is accompanied by fever or other symptoms, stop using Amlexanox and consult a physician or dentist, since these features may indicate a cause other than a simple aphthous ulcer.
