I have taken azithromycin for 3 days-500mg, 1gm, 1gm respectively for chlamydia i want to repeat the course due to alcohol after how much time can i do?

You don't need it: Chlamydia urethritis is treated with 1 dose of 1 gram of azithromycin. It seems that you have already taken much more than is needed cure this type of chlamydial infection. This drug has a long half life and will be actively treating your infection for more than 5 days after your last dose. I don't understand your reference to alcohol. Alcohol does not affect azithromycin.

Ask prescriber: Ask the person who prescribed the medication. But sometimes the course is repeated in a week or more commonly after a couple of weeks. In most cases the 500 mg - 1 g - 1 g treatment would be effective and no further treatment necessary.
