question: Hello Dr. Chakraborty, I am away from home, traveling overseas and I have a tooth infection. Does azithromycin help or should I get amoxicillin? I have a zpack available but I can buy some amoxicillin tomorrow to take until I make it back to my dentist which would be Thursday or Friday only. I know I should take Amox 500 mg 4 times a day/7 days but just wondering if zpack would be as good. Thank you very much! Silvia
