Used to produce local anesthesia of the mucous membranes for procedures such as intubation, endoscopy, bronchoscopy, and other examinations of the mouth, throat, and respiratory tract. May also be used for relief of pain from minor oral conditions.

The combination contains three local anesthetics that work by blocking nerve signal transmission in the applied area. Benzocaine provides rapid onset of action, while tetracaine extends the duration of effect. Butamben contributes additional anesthetic properties.

For topical use only on mucous membranes; not for injection. Should be used with caution in patients with certain heart conditions, methemoglobinemia, or who are pregnant/nursing. Rare but serious methemoglobinemia has been reported with benzocaine-containing products. Dosage and duration should be minimized to reduce risk of systemic absorption.
