Moxifloxacin (Avelox) is a broad-spectrum antibiotic in the Quinolone family. Moxifloxacin is used to treat a variety of bacterial infections. It is widely available in oral and topical (opthalmic) formulations.

Moxifloxacin is rarely used as a treatment for acne. But there is some evidence to suggest that Moxifloxacin can be a useful acne treatment. Laboratory testing indicates that the acne-causing P. acnes bacterium is moderately more susceptible to Moxifloxacin than Ciprofloxacin, which is a more commonly used antibiotic in the Quinolone family.
