What Experts Say

Levofloxacin belongs to the fluoroquinolone class of antibiotics. It works by blocking bacterial DNA gyrase and topoisomerase IV, enzymes bacteria need to replicate. Physicians commonly prescribe it for moderate to severe respiratory infections because it reaches high concentrations in lung tissue and stays effective against many resistant pathogens.

Doctors across Pakistan often reserve fluoroquinolones like levofloxacin for infections that do not respond to first-line antibiotics such as amoxicillin, given the country's rising rates of antibiotic resistance. Culture and sensitivity testing before starting therapy is encouraged, and patients are advised to finish the full course even after symptoms improve.

Levofloxacin carries risks of tendon damage, nerve problems, and heart rhythm changes, so doctors monitor patients closely, especially older adults and those with kidney disease. It is generally avoided in children and during pregnancy unless no safer option exists, and physicians stress that it should only be used under prescription and proper clinical supervision.
