What is an over the counter substitute for gentamycin?

An over-the-counter substitute for gentamicin, which is a prescription antibiotic, is not available, as gentamicin is specifically used for treating bacterial infections and requires a prescription due to its potency and potential side effects. However, for minor infections or skin irritations, topical antibiotics like bacitracin or neomycin (found in products like Neosporin) may be used. It's essential to consult a healthcare professional before using any alternative treatments.
