Lexanox Oral Paste contains Amlexanox 50mg as its active ingredient and is indicated for the treatment of aphthous ulcers (canker sores) and minor oral mucosal irritations. Amlexanox is an anti-inflammatory and anti-allergic agent that acts by inhibiting the release of inflammatory mediators such as histamine and leukotrienes from mast cells, thereby reducing inflammation and promoting healing. Lexanox Oral Paste is applied topically to the affected area of the oral mucosa, providing localized relief from pain and discomfort associated with ulcers. The paste forms a protective barrier over the lesion, minimizing irritation from mechanical trauma and facilitating tissue repair. It is generally well tolerated, with minimal adverse effects reported, though some patients may experience mild local irritation or a transient burning sensation upon application. Lexanox Oral Paste is intended for short-term use and should be applied 4 times daily or as directed by a healthcare professional. Patients should avoid eating or drinking for at least 30 minutes after application to maximize efficacy. Caution is advised in individuals with known hypersensitivity to Amlexanox or any excipients. Consult a healthcare provider if symptoms persist beyond two weeks or worsen.
