Amlexanox is no longer available in the US. If you are currently using amlexanox, you should call your doctor to discuss switching to another treatment.
Amlexanox is used to treat ulcers of the mouth called aphthous ulcers or canker sores. It decreases the time ulcers take to heal. Because amlexanox decreases the healing time, it also decreases the pain you feel.
This medication is sometimes prescribed for other uses; ask your doctor, dentist, or pharmacist for more information.
Amlexanox comes as a beige-colored paste. Amlexanox should be used as soon as possible after noticing symptoms of an ulcer. Amlexanox is usually applied four times a day, following brushing and flossing after breakfast, lunch, dinner, and at bedtime. Squeeze 1/4 inch (0.6 centimeters) of the paste on your finger. With gentle pressure, dab amlexanox onto each ulcer in the mouth. Wash hands immediately after using amlexanox. Amlexanox is only used until the ulcer has healed, usually within 10 days. Contact your physician or dentist if significant healing has not occurred within 10 days.
Follow the directions on your prescription label carefully, and ask your doctor, dentist, or pharmacist to explain any part you do not understand. Use amlexanox exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor or dentist.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
Keep all appointments with your doctor or dentist. Amlexanox is for external use only. Do not let amlexanox get into your eyes. If it does get into your eyes, rinse them promptly.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription. Tell your doctor or dentist if your ulcers get worse or do not get better within 10 days.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
