Zithromax Oral Uses
Azithromycin is an antibiotic (macrolide-type) used to prevent and treat a very serious type of infection (mycobacteria or MAC). It works by stopping the growth of bacteria.
This antibiotic treats only bacterial infections. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
How To Use Zithromax Oral

To treat infection, take this drug usually once a day at the same time each day, or as directed by your doctor. Continue to take this medication until your doctor tells you to stop. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. If symptoms do not improve within 2-4 weeks, contact your doctor.
Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals.
Antacids may decrease the absorption of azithromycin. If you take an antacid, wait at least 2 hours after taking this medication.
