It is important that your doctor check your or your child's progress during and after treatment. This is to make sure that the infection is cleared up completely, and to allow your doctor to check for any unwanted effects. Blood and urine tests may be needed to check for unwanted effects.
If your or your child's symptoms do not improve within a few days, or if they become worse, check with your doctor.
Polymyxin B injection may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop using this medicine. Do not take any medicine to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.
Check with your doctor right away if you feel weak, irritable, drowsy, trouble seeing, numbness or tingling of the arms or legs, or other problems with muscle control.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
