What is a serious side effect of Polymyxins?

  1. Weight gain

  2. Nephrotoxicity

  3. Sore throat

  4. Hair loss

The correct answer is: Nephrotoxicity

Polymyxins is an antibiotic that can cause nephrotoxicity, a serious side effect that can damage the kidneys. It is important to monitor kidney function when taking this medication and to seek medical attention if any symptoms of kidney damage occur. Weight gain, sore throat, and hair loss are not common side effects of Polymyxins and should not be a concern when taking this medication. In fact, weight loss and lack of appetite may occur as a side effect of this antibiotic. Sore throat and hair loss may be signs of other health issues and should be discussed with a healthcare provider if they persist.
