Indications
Indications Cetacaine Topical Anesthetic Gel is a topical anesthetic indicated for the production of anesthesia of all accessible mucous membrane except the eyes. Cetacaine Topical Anesthetic Gel is indicated for use to control pain and for use for surgical or endoscopic procedures, or other procedures in the ear, nose, mouth, pharynx, larynx, trachea, bronchi, and esophagus. It may also be used for vaginal or rectal procedures where feasible.
Contraindications
Contraindications Do not use Cetacaine Gel to treat infants or children younger than 2 years. Cetacaine is not suitable and should never be used for injection. Do not use on the eyes. To avoid excessive systemic absorption, Cetacaine Topical Anesthetic Gel should not be applied to large areas of denuded or inflamed tissue. Cetacaine Topical Anesthetic Gel should not be administered to patients who are hypersensitive to any of its ingredients or to patients known to have cholinesterase deficiencies.
Tolerance may vary with status of the patient. Cetacaine Topical Anesthetic Gel should not be used under dentures or cotton rolls, as retention of the active gel ingredients under a denture or cotton roll could possibly cause an escharotic effect. Routine precaution for the use of any topical anesthetic should be observed when using Cetacaine Topical Anesthetic Gel.
Warnings and precautions
Methemoglobinemia Cases of methemoglobinemia have been reported in association with local anesthetic use. Although all patients are at risk for methemoglobinemia, patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, infants under 6 months of age, and concurrent exposure to oxidizing agents or their metabolites are more susceptible to developing clinical manifestations of the condition.
If local anesthetics must be used in these patients, close monitoring for symptoms and signs of methemoglobinemia is recommended. Signs and symptoms of methemoglobinemia may occur immediately or may be delayed some hours after exposure and are characterized by a cyanotic skin discoloration and abnormal coloration of the blood. Methemoglobin levels may continue to rise; therefore, immediate treatment is required to avert more serious central nervous system and cardiovascular adverse effects, including seizures, coma, arrhythmias, and death.
