Amlexanox
About Amlexanox
Amlexanox 5% oral paste is a topical medicine applied directly to painful mouth ulcers, commonly known as canker sores. It is designed to act locally on the affected oral tissue and should not be swallowed intentionally. It is clinically designed to speed up the healing process of these sores in people with normal immune systems. By targeting the inflamed tissue directly, it helps reduce both the size of the ulcer and the pain associated with it.
For best results, this medicine must be used consistently and at the exact frequency recommended by your doctor, which is typically four times a day. You should apply it immediately after meals and before going to bed, ensuring you avoid eating or drinking for a short period afterwards. Making simple lifestyle adjustments, such as avoiding spicy or acidic foods, can also significantly improve your recovery.
While using Amlexanox, you may experience mild, temporary stinging or burning at the application site. These are common and usually fade quickly, but you should consult your doctor immediately if you experience severe irritation, swelling of the mouth, or signs of an allergic reaction.
Talk to your doctor before starting this treatment if you have a weakened immune system or other underlying health conditions. Do not use this medicine if you have a known allergy to any of its ingredients.
Inform your doctor about any other oral gels, mouthwashes, or medications you are currently using to avoid potential localised interactions. If you are pregnant, breastfeeding, or managing health conditions in elderly individuals, consult your healthcare provider before application.

Patients Concern
Disease/Condition Glossary
Mouth ulcers: Mouth ulcers, also known as canker sores or aphthous ulcers, are small, painful lesions that develop in the mouth or at the base of the gums. These can make you uncomfortable while eating, drinking, and talking. Mouth ulcers usually heal within a few weeks and are not contagious. People with a family history of canker sores are at more risk. Minor mouth injuries, such as those from dental work or hard brushing, acidic foods, a lack of essential vitamins like vitamin B12, dental braces, emotional stress, and viral, bacterial, or fungal infections, can cause mouth ulcers.
FAQs
Amlexanox is an anti-inflammatory agent, used to treat mouth ulcers by reducing inflammation and promoting healing in the affected area.
Amlexanox contains Amlexanox, which helps treat mouth ulcers inside your lips, gums, the roof of the mouth or throat, and tongue. Amlexanox reduces pain, swelling, and inflammation by blocking the action of chemical substances that cause inflammation. It also forms a protective layer over the ulcer, enabling it to heal more quickly.
Wash your hands immediately after using Amlexanox. Make sure Amlexanox does not get into the eyes. If it accidentally enters your eyes, rinse them thoroughly with water.
Amlexanox is usually well-tolerated and may cause mild and temporary side effects when used at recommended doses. Amlexanox may cause side effects such as pain, stinging, or burning sensations at the application site. Inform your physician if any of these side effects persist or worsen.
If the mouth ulcers last longer than 3 weeks, present in unusually large size, become painful, bleed, or frequently develop, consult your physician immediately.
Avoid eating within 1 hour after using Amlexanox. It is recommended to take Amlexanox after meals to avoid swallowing the medicine unless otherwise advised by your physician.
Amlexanox should only be used for the duration prescribed by your doctor, based on your condition. Using Amlexanox for a more extended period than recommended may lead to side effects such as pain, stinging, or a burning sensation at the application site. If you feel the need to continue the medication for a longer time, please consult your doctor.
The use of Amlexanox may cause diarrhoea as a side effect in some individuals. If diarrhoea occurs, stay hydrated by drinking water and avoid foods that may irritate your stomach. If diarrhoea continues, please consult your doctor. Do not take any antidiarrheal medical unless advised by the doctor.
Amlexanox is not typically used to treat skin ulcers. It is primarily used as a medication for conditions such as mouth ulcers or canker sores. Treatment for skin ulcers typically involves wound care, antibiotics, or other targeted medications, depending on the underlying cause. Please consult your doctor for the most appropriate treatment options for skin ulcers.
Acidic or citrus fruits (such as oranges and lemons), spicy foods (like hot peppers), salty foods (like chips), and crunchy foods (like nuts or crackers) can irritate mouth ulcers. Additionally, rough-textured foods (such as toast) and sugary snacks can exacerbate ulcers, slowing the healing process.
Mouth ulcers are small, painful sores that can appear inside the mouth. They are often caused by factors such as emotional stress, minor injuries (e.g., from dental work or hard brushing), certain foods (such as spicy or acidic ones), or nutritional deficiencies (like vitamin B12). In some cases, they may be linked to infections (viral, bacterial, or fungal), autoimmune conditions, or other health issues.
There is limited clinical data on the safety of using this product during pregnancy or while breastfeeding. Because it is applied locally, systemic absorption is very low, but you should still consult your healthcare provider to discuss the potential risks and benefits. Talk to your doctor.
The safety and efficacy of this medication in children have not been fully established. Do not apply this paste to a child's mouth ulcers unless a pediatrician specifically instructs you to do so. Talk to your doctor.

It is best to avoid using harsh or alcohol-based mouthwashes directly before or after applying the paste, as they can wash away the medication or cause further irritation. If you must use mouthwash, do so well before your scheduled application. Talk to your doctor.
Amlexanox may begin relieving pain and discomfort within a few hours to a few days after application. With regular use, most mouth ulcers heal within about 7 to 10 days, although healing time depends on the size and severity of the ulcer. If your ulcer has not improved after 10 days or becomes worse, stop using the medication and consult your doctor.
