The drug is an antibiotic used to treat a variety of bacterial infections, such as cat-scratch disease, ear infections, infections of the skin or surrounding tissue, and throat or tonsil infections.

The FDA first approved azithromycin under the brand name Zithromax in 1991. Pfizer Pharmaceuticals manufactures the drug.
