Levofloxacin is a fluoroquinolone antibiotic used to treat a wide range of bacterial infections such as pneumonia, bronchitis, urinary tract infections (UTIs), and skin infections. It works by inhibiting bacterial enzymes, preventing the bacteria from reproducing and spreading. While effective, levofloxacin may cause side effects, including nausea, dizziness, and tendon issues. It’s essential to follow medical advice to reduce risks and complete the prescribed treatment.
