Ciprofloxacin is a fluoroquinolone antibiotic used to treat a number of bacterial infections.[4] This includes bone and joint infections, intra-abdominal infections, certain types of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others.[4] For some infections it is used in addition to other antibiotics.[4] It can be taken by mouth, as eye drops, as ear drops, or intravenously.[4][5]

Common side effects include nausea, vomiting, and diarrhea.[4] Severe side effects include tendon rupture, hallucinations, and nerve damage.[4] In people with myasthenia gravis, there is worsening muscle weakness.[4] Rates of side effects appear to be higher than some groups of antibiotics such as cephalosporins but lower than others such as clindamycin.[6] Studies in other animals raise concerns regarding use in pregnancy.[7] No problems were identified, however, in the children of a small number of women who took the medication.[7] It appears to be safe during breastfeeding.[4] It is a second-generation fluoroquinolone with a broad spectrum of activity that usually results in the death of the bacteria.[4][8][9]

Ciprofloxacin was patented in 1980 and introduced by Bayer in 1987.[10][11] It is on the World Health Organization's List of Essential Medicines.[12] The World Health Organization classifies ciprofloxacin as critically important for human medicine.[13] It is available as a generic medication.[4][14] In 2022, it was the 181st most commonly prescribed medication in the United States, with more than 2 million prescriptions.[15][16]
