Levofloxacin (Levaquin) is which type of medication?

• A. Antisa-dher
• B. Antibiotic
• C. Antihistamine
• D. Antipsychotic

Answer: (B)

Levofloxacin is an antibiotic, specifically a fluoroquinolone. It works by inhibiting bacterial enzymes needed for DNA replication (DNA gyrase and topoisomerase IV), so bacteria can’t multiply and are killed. This makes it effective against many bacterial infections, but it won’t treat viral illnesses like colds or the flu. It’s not an antihistamine or an antipsychotic, which are used for allergy symptoms or mental health conditions. Safety notes to remember: there is a risk of tendon injury or rupture, especially in older adults or those on steroids; absorption can be reduced if taken with iron or calcium-containing antacids or supplements within a couple hours of the dose; and there is a potential for photosensitivity and C. difficile–related diarrhea.
