Common Use
Azithromycin is a semi-synthetic macrolide antibiotic chemically related to erythromycin. It is active against most species of gram-positive and gram-negative microorganisms such as Staphylococcus genus; S. aureus, S. pneumonia, S. pyogenes, S. agalactiae, Haemophilus influenza and parainfluenza, Moraxella catarrhalis, Bacteroides fragilis, Escherichia coli, Bordetella spp., Borrelia burgdorferi, Haemophilus decree, Neisseria gonorrhoeae, and Chlamydia trachoma. In vitro, it showed activity against Legionella pneumophila, Mycoplasma pneumonia hominis, Helicobacter pylori, Toxoplasma gondii, Ureaplasma urealiticum. As a macrolide antibiotic, Azithromycin inhibits bacterial protein synthesis and prevents bacteria from growth and propagation. It is used to treat infections of the upper and lower respiratory organs (tonsillitis, otitis, sinusitis, pneumonia), urogenital infections (urethritis, prostatitis, cervicitis, adnexitis caused by chlamydia, gonorrhea, early syphilis), intestinal infections, and ulcers of the stomach and duodenum.

Take Azithromycin exactly as prescribed and do not discontinue your treatment even if you feel fine and your symptoms improve without your doctor’s permission. Take the Azithromycin tablet with a large glass of water. To prepare a liquid suspension, mix one dose packet with 2 ounces of water, shake, and drink immediately. Do not use the suspension if it was prepared more than 12 hours ago. Tablets and suspensions can be taken with or without food, while capsules should be taken on an empty stomach 2 hours before or after a meal.
