Fluoroquinolones are a class of antibiotics used to treat various bacterial infections. They work by inhibiting the enzymes that bacteria need to replicate their DNA, effectively stopping the growth and spread of the infection. Commonly prescribed fluoroquinolones include ciprofloxacin and levofloxacin. These medications are often used for respiratory, urinary tract, and gastrointestinal infections. While generally effective, fluoroquinolones can have side effects, including gastrointestinal issues and, in some cases, tendon damage. It's important for patients to discuss potential risks with their healthcare provider before starting treatment.
