Azithromycin, sold under the brand names Zithromax (in oral form) and Azasite (as an eye drop), is an antibiotic medication used for the treatment of a number of bacterial infections.[10] This includes middle ear infections, strep throat, pneumonia, traveler's diarrhea, and certain other intestinal infections.[10] Along with other medications, it may also be used for malaria.[10] It is administered by mouth, into a vein, or into the eye.[10]
Common side effects include nausea, vomiting, diarrhea and upset stomach.[10] An allergic reaction, such as anaphylaxis, or a type of diarrhea caused by Clostridium difficile is possible.[10] Azithromycin causes QT prolongation that may cause life-threatening arrythmias such as torsades de pointes.[11] No harm has been found with its use during pregnancy.[10] Its safety during breastfeeding is not confirmed, but it is likely safe.[12] Azithromycin is an azalide, a type of macrolide antibiotic.[10] It works by decreasing the production of protein, thereby stopping bacterial growth.[10][13]
Azithromycin was discovered in former Yugoslavia (present day Croatia) in 1980 by the pharmaceutical company Pliva and approved for medical use in 1988.[14][15] It is on the World Health Organization's List of Essential Medicines.[16] The World Health Organization lists it as an example under "Macrolides and ketolides" in its Critically Important Antimicrobials for Human Medicine (designed to help manage antimicrobial resistance).[17] It is available as a generic medication[18] and is sold under many brand names worldwide.[1] In 2021, it was the 97th most commonly prescribed medication in the United States, with more than 7 million prescriptions.[19][20]
