Gatifloxacin (Tequin) is an antibiotic in the Quinolone family. Gatifloxacin is used to treat certain types of respiratory and eye infections.

Gatifloxacin is rarely used as a treatment for acne and there is limited evidence regarding its efficacy as an acne treatment. Other Quinolone family antibiotics are more commonly used in acne treatment regimens. Gatifloxacin is available in oral and topical formulations. The topical formulations are generally designed for opthalmic use, but Gatifloxacin ointments could be applied directly to the skin.

Gatifloxacin is associated with more frequent severe side effects than many other comparable antibiotics. Because of the elevated risk of side effects, Gatifloxacin is no longer available in many countries.
