To treat infection, take this drug as directed by your doctor, usually once daily at the same time each day. Continue to take this medication until your doctor tells you to stop. Stopping the medication too early on your own may allow bacteria to continue to grow, which may result in a return of the infection. Tell your doctor if your condition persists or worsens.
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 containing aluminum or magnesium may decrease the absorption of azithromycin if taken at the same time. If you take an antacid that contains aluminum or magnesium, wait at least 2 hours before or after taking azithromycin.
