Lidocaine Hydrochloride Oral Topical Solution should be used with extreme caution if the mucosa in the area of application has been traumatized, since under such conditions there is the potential for rapid systemic absorption. The lowest dosage that results in effective anesthesia should be used to avoid high plasma levels and serious adverse effects.
Tolerance varies with the status of the patient.
Debilitated, elderly patients, acutely ill patients, and children should be given reduced doses commensurate with their age, weight and physical condition. Lidocaine should also be used with caution in patients with severe shock or heart block. Lidocaine Hydrochloride Oral Topical Solution should be used with caution in persons with known drug sensitivities. When topical anesthetics are used in the mouth or throat, the patient should be aware that the production of topical anesthesia may impair swallowing and thus enhance the danger of aspiration. For this reason, food should not be ingested for 60 minutes following use of local anesthetic preparations in the mouth or throat area.
