Chlamydia: The dose of azithromycin used to treat chlamydial infections is usually 1000 mg. A half dose of 500 mg may be effective in a person of smaller stature with a mild infection.
Dr. Jeffrey Levine

Not indicated dose: The recommended dose of Azithromycin for Chlamydia is 1000mg (1gm) x 1 dose, not 500mg. You should be tested for Chlamydia and other STis. I encourage you to use condoms or dental dams for oral sex to reduce your risk of STIs.
