Hello,
Zithromax contains azithromycin and is mostly used for STD’s like non gonococcal urethritis and cervicitis due to Chlamydia
trachomatis. It is usually not the drug of choice for UTI but is mostly used in otitis media (infection of the middle ear), tonsillitis, laryngitis, bronchitis, pneumonia, and sinusitis.
I hope it helps. Take care and regards.
