Neomycin Sulfate

Neomycin sulfate is classified as an aminoglycoside antibiotic. It is a custom pharmacy drug that has many uses in modern medicine. Neomycin sulfate is a chief antibiotic chosen by doctors for the treatment of infections. Neomycin sulfate works by attacking and stopping the growth of bacteria. It is used topical and also orally, depending on the patient's condition, and is a common drug given after intestinal surgeries to prevent possible infection, to treat hepatic encephalopathy, and other bacterial infections internally and externally. As a topical treatment, neomycin sulfate, is a key ingredient in widely used ointments such as the popular, Neosporin ointment.


For conditions such as hepatic encephalopathy, and for post-surgical bacterial infection protection, neomycin sulfate is taken orally, often in tablet form. Dosage and length of the course depends on the specific condition of the patient.

For topical treatments, neomycin sulfate comes in various forms, such as the common ointment. Treat the affected area with a small amount of the ointment, just enough to cover the area with a thin layer. Consult with your compounding pharmacist if you have further questions about any of the forms of this medication.
