Kanamycin Polymyxin B Sulfate
MajorTaking kanamycin together with Polymyxin B Sulfate, or one right after the other, should be avoided. Both medicines can harm the nerves and the kidneys, so using them together raises the chance of that damage. If you have been prescribed both, don't stop or change either one on your own. Ask your doctor or pharmacist first.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
