WARNINGS: CONCERNS RELATED TO ADVERSE EFFECTS: Methemoglobinemia: Has been reported with local anesthetics; clinically significant methemoglobinemia requires immediate treatment along with discontinuation of the anesthetic and other oxidizing agents. Onset may be immediate or delayed (hours) after anesthetic exposure. Patients with G6PD deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, exposure to oxidizing agents or their metabolites, or infants <6 months of age are more susceptible and should be closely monitored for signs and symptoms of methemoglobinemia (including pale, gray, or blue-colored skin (cyanosis), headache, rapid pulse, shortness of breath, lightheadedness, fatigue). WARNINGS: For external use only. Not for ophthalmic use. Stop use and ask a doctor if condition worsens or symptoms last more than 7 days or clear up and occur again within a few days. Do not apply to wounds or damaged skin. Do not use in large quantities, particularly over raw surfaces or blistered areas. If swallowed, get medical help or contact a Poison Control Center right away. Keep out of reach of children. Topical formulations of lidocaine may be absorbed to a greater extent through mucous membranes and abraded, fissured or irritated skin than through intact skin. Product should not be ingested or applied into the mouth, inside of the nose or in the eyes. Product should not be used in the ears. Any situation where lidocaine penetrates beyond the tympanic membrane into the middle ear is contraindicated because of ototoxicity associated with lidocaine observed in animals when instilled in the middle ear. Product should not come into contact with the eye or be applied into the eye because of the risk of severe eye irritation and the loss of eye surface sensation, which reduces protective reflexes and can lead to corneal irritation and possibly abrasion. If eye contact occurs, rinse out the eye immediately with saline or water and protect the eye surface until sensation is restored.
ADVERSE REACTIONS: During or immediately following application of product, there may be transient stinging or burning from open areas of skin, or transient blanching (lightening), or erythema (redness) of the skin.
