@alisha-- Can you drink alcohol on azithromycin? Yes, a little bit. But should you? Not really.
I personally don't think it's a good idea to drink while on any medication. I didn't drink while I was on azithromycin even though my doctor would have probably allowed it.
Alcohol isn't good for the body because it causes so many changes. It's a diuretic and causes dehydration. It depresses the central nervous system and makes it difficult to think and perform activities. Alcohol is also said to weaken the immune system. I believe it because the liver treats alcohol as a toxin and leaves everything else it's metabolizing to metabolize alcohol and get it out of the body first.
When I'm already sick and my body is fighting an infection, the last thing I need is a weak immune system and an over-stressed liver. So I don't drink any alcohol while I'm sick and on medications. It's just common sense.
