Urinide Bumetanide Polymyxin B Sulfate
MajorAvoid using Polymyxin B Sulfate and bumetanide together, whether at the same time or one soon after the other. The leaflet lists bumetanide among the medicines that can harm the nerves or the kidneys. Polymyxin B can do the same, so using the two together can add to that risk. If both have been prescribed for you, talk to your doctor or pharmacist before taking either one.
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.
