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. Discontinue Cetacaine and any other oxidizing agents. Depending on the severity of the symptoms, patients may respond to supportive care, i.e., oxygen therapy, hydration. More severe symptoms may require treatment with methylene blue, exchange transfusion, or hyperbaric oxygen."],"pregnancy":["Use in Pregnancy Safe use of Cetacaine has not been established with respect to possible adverse effects upon fetal development.

Cetacaine is not suitable and should never be used for injection. Do not use on the eyes. To avoid excessive systemic absorption, Cetacaine should not be applied to large areas of denuded or inflamed tissue. Cetacaine 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 the status of the patient. Cetacaine should not be used under dentures or cotton rolls, as retention of the active ingredients under a denture or cotton roll could possibly cause an escharotic effect.

This effect is due to the rapid onset, but short duration of action of Benzocaine coupled with the slow onset, but extended duration of Tetracaine HCI and bridged by the intermediate action of Butamben. These agents act by reversibly blocking nerve conduction. Speed and duration of action is determined by the ability of the agent to be absorbed by the mucous membrane and nerve sheath and then to diffuse out, and ultimately be metabolized (primarily by plasma cholinesterases) to inert metabolites which are excreted in the urine."],"storage_and_handling":["Store at controlled room temperature 20-25°C (68-77°F)"],"indications_and_usage":["Indications Cetacaine is a topical anesthetic indicated for the production of anesthesia of all accessible mucous membrane except the eyes.

Advise patients or caregivers to stop use and seek immediate medical attention if they or someone in their care experience the following signs or symptoms: pale, gray, or blue colored skin (cyanosis); headache; rapid heart rate; shortness of breath; lightheadedness; or fatigue. Hypersensitivity Reactions Unpredictable adverse reactions (i.e. hypersensitivity, including anaphylaxis) are extremely rare. Localized allergic reactions may occur after prolonged or repeated use of any aminobenzoate anesthetic. The most common adverse reaction caused by local anesthetics is contact dermatitis characterized by erythema and pruritus that may progress to vesiculation and oozing. This occurs most commonly in patients following prolonged self-medication, which is contraindicated. If rash, urticaria, edema, or other manifestations of allergy develop during use, the drug should be discontinued. To minimize the possibility of a serious allergic reaction, Cetacaine preparations should not be applied for prolonged periods except under continual supervision. Dehydration of the epithelium or an escharotic effect may also result from prolonged contact. Use in Pregnancy Safe use of Cetacaine has not been established with respect to possible adverse effects upon fetal development. Therefore, Cetacaine should not be used during early pregnancy, unless in the judgement of a physician, the potential benefits outweigh the unknown hazards.

Only a limited quantity of Cetacaine is required for anesthesia. Spray in excess of two seconds is contraindicated. Each one-second spray contains an average of 200 mg of product, not including propellant. To apply, insert the cannula firmly onto the protruding plastic stem on the bottle and press the cannula forward to actuate the spray valve. The cannula may be removed and reinserted as many times as required for cleaning, or sterilization, and is autoclavable. Cetacaine Liquid Apply 200 mg liquid (approximately 0.2 mL) directly to tissue. Liquid in excess of 400 mg (approximately 0.4 mL) is contraindicated. To apply, remove and discard the shipping cap from the bottle. Replace it with the supplied Luer-lock cap. Caution: Do not over-tighten. Remove small cap from luer-lock port, retaining it for replacement after use. Port allows for a single dip of a cotton or brush applicator for application directly to accessible mucous membrane. For application into periodontal pockets, Cetylite Luer-lock syringes and Microcapillary Delivery Tips are recommended. Cetylite Syringes are clearly marked in (4) 0.1 mL increments. To fill, attach syringe to port by gently twisting clockwise until secure. Invert and draw desired amount of liquid into the syringe. Remove filled syringe and attach Microcapillary Delivery Tip to the syringe. Tip may be bent to improve access. Apply drop-wise to accessible mucous membrane (such as buccal and lingual sulcus) by slowly depressing the syringe plunger. Discard all applicators after use. An appropriate pediatric dosage has not been established for Cetacaine Spray or Cetacaine Liquid. Dosages should be reduced in the debilitated elderly, acutely ill, and very young patients (i.e., children 2 years and older). Do not use Cetacaine Spray or Cetacaine Liquid to treat infants or children younger than 2 years. Tissue need not be dried prior to application of Cetacaine. Cetacaine should be applied directly to the site where pain control is required. Anesthesia is produced within one minute with an approximate duration of thirty minutes. Each 200 mg dose of Cetacaine (Spray or Liquid) contains 28 mg of benzocaine, 4 mg of butamben and 4 mg of tetracaine HCl."],"spl_product_data_elements":["Cetacaine Anesthetic Benzocaine, Butamben, and Tetracaine Hydrochloride Benzocaine Benzocaine Butamben Butamben Tetracaine Hydrochloride Tetracaine Dipropylene glycol Saccharin Benzalkonium chloride Mecetronium Bromide Cetacaine Anesthetic Benzocaine, Butamben, and Tetracaine Hydrochloride Benzocaine Benzocaine Butamben Butamben Tetracaine Hydrochloride Tetracaine Dipropylene glycol Saccharin Benzalkonium chloride Mecetronium Bromide Cetacaine Anesthetic Benzocaine, Butamben, and Tetracaine Hydrochloride Benzocaine Benzocaine Butamben Butamben Tetracaine Hydrochloride Tetracaine Dipropylene glycol Saccharin Benzalkonium chloride Mecetronium Bromide"],"spl_unclassified_section_table":["<table width=\"65%\" styleCode=\"Noautorules\"><col width=\"80%\" align=\"left\" valign=\"bottom\"/><col width=\"20%\" align=\"right\" valign=\"bottom\"/><tfoot><tr><td colspan=\"2\" align=\"left\" valign=\"top\">In a bland, water-soluble base.</td></tr></tfoot><tbody><tr><td colspan=\"2\"><content styleCode=\"bold\">Active ingredients</content></td></tr><tr><td>Benzocaine</td><td>14.0%</td></tr><tr><td>Butamben</td><td>2.0%</td></tr><tr><td>Tetracaine Hydrochloride</td><td>2.0%</td></tr><tr><td colspan=\"2\"><content styleCode=\"bold\">Contains</content></td></tr><tr><td>Benzalkonium Chloride</td><td>0.5%</td></tr><tr><td>Cetyl Dimethyl Ethyl Ammonium Bromide</td><td>0.005%</td></tr></tbody></table>"],"package_label_principal_display_panel":["PRINCIPAL DISPLAY PANEL - 11 g Bottle Box NDC 10223-0202-7 Item No. 0223 Cetacaine ® Topical Anesthetic LIQUID With Luer-lock Dispenser Cap 11g Control Pain Effective Only on Mucous Membrane CETYLITE ® PRINCIPAL DISPLAY PANEL - 11 g Bottle Box","PRINCIPAL DISPLAY PANEL - 24 g Bottle Box NDC 10223-0202-8 Item No. 0224 Cetacaine ® Topical Anesthetic LIQUID With Luer-lock Dispenser Cap 24g Control Pain Effective Only on Mucous Membrane CETYLITE ® PRINCIPAL DISPLAY PANEL - 24 g Bottle Box","PRINCIPAL DISPLAY PANEL - 11 g Bottle Kit OPEN HERE Cetacaine ® Topical Anesthetic LIQUID (Benzocaine 14.0%, Butamben 2.0%, and Tetracaine Hydrochloride 2.0%) Chairside Kit CETYLITE ® PRINCIPAL DISPLAY PANEL - 11 g Bottle Kit","PRINCIPAL DISPLAY PANEL - 24 g Bottle Kit NDC 10223-0226-1 ITEM NO: 0226 Cetacaine ® TOPICAL ANESTHETIC LIQUID CLINICAL KIT (Benzocaine 14.0%, Butamben 2.0%, and Tetracaine HCl 2.0%) Featuring a Unique Dispenser Cap for Accurate Filling of Luer-lock Syringes KIT CONTAINS: 1 24g bottle of Cetacaine Liquid 1 Luer-lock dispenser cap 100 Microcapillary Delivery Tips 100 Delivery Syringes CETYLITE ® Rx Only CAUTION: Not for injection.
