Polymyxin B (polymyxin b sulfate) is an antibiotic used to treat bacterial infections such as urinary tract infections, meningitis, blood infections, and eye infections. Polymyxin B is available in generic form. Common side effects of Polymyxin B include:

  • pain,
  • redness, and
  • swelling at the injection site, or
  • temporary eye stinging/burning/redness/itchiness or
  • temporary blurred vision if used as eye drops.

Contact your doctor if you experience serious side effects of Polymyxin B including:

  • flushing,
  • dizziness,
  • loss of coordination,
  • drowsiness,
  • fever,
  • headache,
  • numbness or tingling in the hands or feet,
  • back pain,
  • stiff neck,
  • unsteadiness,
  • hives, and
  • rash.

Polymyxin B dose is determined by a doctor, based on the condition being treated. It may be injected into a vein, muscle, or the spinal fluid or into the area around the eye (subconjunctival sac). It can also be prepared as eye drops. Polymyxin B may interact with other drugs that can harm the kidneys or nerves (e.g., cisplatin, colistin, high-dose aspirin, aminoglycosides such as amikacin, gentamicin, tobramycin, nonsteroidal anti-inflammatory drugs-NSAIDs such as ibuprofen or naproxen). Tell your doctor all medications you are taking. During pregnancy, Polymyxin B should be used only when prescribed. It is unknown if this medication passes into breast milk when used in the eye. It is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.
