This is not a complete list of adverse effects – though these are among the most common. Seek medical attention right away if you experience symptoms such as swelling that does not go away, hives, rash, itching, or irritation while using polymyxin B. Because you may experience blurred vision after applying ophthalmic polymyxin B, do not operate cars or other forms of machinery immediately after using this medication.
As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with, and any medication/ supplements you are currently taking before starting treatment with polymyxin B. Polymyxin B can interact with other forms of medication and substances, causing potentially serious side effects. In addition, let your doctor know if you are pregnant or plan on becoming pregnant before starting treatment with this medication.
