Bonjela Adult is an oral gel used to provide relief from the discomfort of mouth ulcers and denture sores. Its active ingredients are choline salicylate, an anti-inflammatory that reduces swelling and discomfort, and cetalkonium chloride, an antiseptic that helps prevent infection. To apply, use a clean finger to gently rub a small amount of the gel onto the affected area. This can be done every 3 hours, or as advised by a healthcare professional. While generally safe, Bonjela Adult may cause a mild burning sensation upon application and is not recommended for use in children under 16 due to the risk of Reye's syndrome.
