Polymyxin B Sulfate/Trimethoprim eye drops are used to topically treat bacterial infections such as conjunctivitis and blepharitis. The medication contains two antibiotics. Polymyxin B kills the bacteria while Trimethoprim stops the growth of the bacteria. This medicine only works for bacterial infections, not other types of eye infections.
