Understanding Levofloxacin: Uses and Benefits

Levofloxacin is part of a class of antibiotics known as fluoroquinolones, renowned for their potency against a wide range of bacterial infections. Doctors prescribe it to treat various infections such as urinary tract infections, respiratory infections, sinusitis, and more. The medication works by inhibiting bacterial DNA synthesis, impeding the growth and spread of harmful bacteria.

However, like any medication, Levofloxacin is not without its risks. It’s essential to be informed about potential side effects, which can vary from mild to severe. Understanding these side effects empowers you to recognize any adverse reactions and seek prompt medical attention when necessary.
