Neomycin/Polymyxin/Dexamethasone is a combination medicine used in the treatment of bacterial infections. Specifically, this combination is used in the treatment of ophthalmic infections. The medicine has three components: Neomycin and Polymyxin (which are antibiotics) and Dexamethasone (which is a steroid). The combination medicine is available as an eye drop or ointment.
Neomycin belongs to the aminoglycoside class of drugs, which works as a protein synthesis inhibitor. Dexamethasone is a steroid medicine which works by controlling the inflammatory process, whereas Polymyxin B works by altering the permeability of the bacterial cell membrane - compromising the integrity of the cell.
Common side effects with Neomycin/Polymyxin/Dexamethasone include stinging, burning, and blurred vision.
