How It Works

Azithromycin belongs to a class of antibiotics called macrolides. It works by inhibiting the growth of bacteria in the body. Specifically, azithromycin binds to the 50S ribosomal subunit of bacterial ribosomes, interfering with protein synthesis and ultimately killing the bacteria.

Unlike many other antibiotics, azithromycin has a long half-life, which means it stays active in the body for an extended period of time. This allows for once-daily dosing and shorter treatment durations compared to some other antibiotics.

The mechanism of action of azithromycin makes it effective against a wide range of bacteria, including Gram-positive and Gram-negative bacteria, as well as atypical pathogens like Mycoplasma, Chlamydia, and Legionella.

Dosage and Administration

Azithromycin is typically taken orally, with or without food, once a day as directed by your healthcare provider. It is important to take the medication exactly as prescribed to ensure its effectiveness.

For most infections, the usual dosage of azithromycin is a single dose of 500mg or 1000mg, depending on the severity of the infection. However, your doctor may adjust the dosage based on your condition and medical history.


Azithromycin can be taken with a full glass of water. It is important to swallow the medication whole and not chew it. If you are taking the oral suspension form of azithromycin, be sure to shake the bottle well before measuring the dose. Use a measuring spoon or syringe to ensure the correct dosage.
