Erythromycin precautions

List of precautions
General Overuse Myasthenia Gravis Impaired Hepatic Function

General
Prescribing ERYC in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. Return to top

Overuse
Prolonged or repeated use of erythromycin may result in an overgrowth of nonsusceptible bacteria or fungi. If superinfection occurs, erythromycin should be discontinued and appropriate therapy instituted. Return to top

Myasthenia Gravis
There have been reports that erythromycin may aggravate the weakness of patients with myasthenia gravis. Return to top

Impaired Hepatic Function
Since erythromycin is principally excreted by the liver, caution should be exercised when erythromycin is administered to patients with impaired hepatic function. Return to top
