Medical and Pharmacy Editor:

PREGNANCY: There are no adequate studies of azithromycin in pregnant women. Azithromycin should only be used during pregnancy if it is clearly necessary.

NURSING MOTHERS: It is not known if azithromycin is secreted in breast milk.

SIDE EFFECTS: Azithromycin is generally well tolerated. The most common side effects are diarrhea or loose stools, nausea, abdominal pain, and vomiting which may occur in fewer than one in twenty persons who receive azithromycin. Rare side effects include abnormal liver tests, allergic reactions, nervousness, and abnormal heart beats. Antibiotics can alter the normal bacteria in the colon and encourage overgrowth of some bacteria such as Clostridium difficile which causes inflammation of the colon (pseudomembranous colitis). Patients who develop signs of pseudomembranous colitis after starting azithromycin (diarrhea, fever, abdominal pain, and possibly shock) should contact their physician immediately.
