Omedia Disease Interactions

There are 2 disease interactions with Omedia (benzocaine otic).

Major

Otic agents (applies to Omedia) 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.

Moderate

Benzocaine (applies to Omedia) 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

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor 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.
Unknown No interaction information available.
