what is zithromax used for

Zithromax (azithromycin) is an antibiotic that fights bacteria. It is used to treat a wide variety of bacterial infections, such as respiratory infections, skin infections, ear infections, and sexually transmitted diseases. Zithromax is also used to prevent infections by a bacterium called Mycobacterium Avium-intracellulare Complex (MAC) in some people. It works by stopping the growth of bacteria causing the infection. Zithromax should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. It is important to take Zithromax as prescribed by a doctor and to complete the full course of treatment, even if symptoms improve before the medication is finished.
