Neobacin Neomycin Sulfate + Bacitracin Zinc Polymyxin B Sulfate
ModerateTaking Polymyxin B Sulfate together with Neomycin Sulfate + Bacitracin Zinc can add to the harm each one can do to the kidneys and the nerves. The combined effect on the kidneys and nerves can be greater than either medicine alone. Use them together only if your doctor has prescribed both.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
