Cetacaine Topical Anesthetic (benzocaine, aminobenzoate and tetracaine) is a topical anesthetic used on mucosal membranes to suppress the gag reflex, control pain and ease discomfort during dental and medical procedures. Common side effects include redness, itching, or swelling where the anesthetic was applied.
Cetacaine Spray is applied for approximately one second or less for normal anesthesia. Only a limited quantity of Cetacaine is required for anesthesia. Cetacaine may interact with other drugs. Tell your doctor all medications and supplements you use. Cetacaine should not be used during early pregnancy. Later during pregnancy, Cetacaine should be used only if prescribed. Consult your doctor before breastfeeding.

Cetacaine FDA Prescribing Information: Side Effects
Hypersensitivity Reactions: Unpredictable adverse reactions (ie, 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 charaterized 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 (benzocaine, aminobenzoate and tetracaine) 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.
