Dosage & Administration

Adult : 500 mg once daily


Azithromycin is contraindicated is patients with a know hypersensitivity to Azithromycin or any of the macrolide antibiotics. Because of the theoretical possibility of ergotism, Azithromycin and Ergot derivatives should not be co-administered. As with erythromycin and other macrolides, rare serious allergic reactions, including angioneurotic edema and anaphylaxis, have resulted in recurrent symptoms and required a long period of observation and treatment.

Side Effects

Azithromycin is well tolerated with a low incidence of side-effects. The side-effects include nausea, vomiting, abdominal discomfort (pain/cramps). flatulence, diarrhoea, headache, dizziness, and skin rashes are reversible upon discontinuation of therapy. Reversible elevations in liver transaminases have been observed occasionally.

Pregnancy & Lactation

Pregnancy : US FDA pregnancy category B. In the animal studies, no evidence of harm to the fetus due to Azithromycin was found. Because animal reproduction studies are not always predictive of human response, Azithromycin should be use during pregnancy only if clearly needed. Lactation : It is not known whether Azithromycin is excreted in human milk. Caution should be exercised when Azithromycin is administered to nursing mother.


As with any antibiotic, observation for sings of superinfection with non susceptible organism, including fungi is recommended.
