Benzotic (benzocaine otic) Disease Interactions
There are 2 disease interactions with Benzotic (benzocaine otic):
Otic agents (applies to Benzotic) perforated tympanic membrane
Major Potential Hazard, High plausibility. Applicable conditions: Chronic Otitis Media
The use of medications that are intended for the treatment of otitis externa or other conditions of the external ear canal should generally be avoided, or otherwise approached with caution, in patients with a perforated tympanic membrane due to the risk of toxicity from medication that may get into the middle ear. Caution is also advised in patients with longstanding, chronic otitis media because of the possibility of a perforated tympanic membrane in such patients.

Benzocaine (applies to Benzotic) methemoglobinemia
Moderate Potential Hazard, Low plausibility. Applicable conditions: G-6-PD Deficiency
Rarely, benzocaine has induced methemoglobinemia resulting in respiratory distress and cyanosis. Therapy with benzocaine should be administered cautiously to patients with or predisposed to methemoglobinemia. If life-threatening or severe methemoglobinemia develops, methylene blue infused at a dosage of 1 to 2 mg/kg body weight will rapidly reverse or improve the condition except in G-6-PD-deficient patients.

Drug Interaction Classification
|Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.|
|Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.|
|Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.|
|No interaction information available.|
