Azee 500 is a formulation of the antibiotic Azithromycin, which is commonly used to treat various types of respiratory infections. Azithromycin belongs to a group of antibiotics called macrolides, which work by interfering with the synthesis of proteins in bacteria, thus stopping their growth. Azithromycin is often prescribed to treat conditions such as pneumonia, bronchitis, sinus infections, and strep throat. It is usually taken by mouth in the form of tablets or a liquid suspension, and is usually administered in a dosage schedule of one dose on the first day, followed by a lower dose for the next four days.
