I was prescribed azithromycin 500mg tablets once per day for 10 days. lactose intolerant and have been dairy free for over a year. i took first dose today and had diarrhea 2 hrs later. how likely is this related to lactose intolerance vs. other?

Antibiotics kill bacteria. This is great for infections, but not so great for your normal stomach/intestinal flora. Try taking a probiotic daily while you are taking the antibiotics and continue with your dairy free diet to avoid additional irritation.
