I am allergic to Amoxicillin, Keflex, Cipro, Bactrim, Flagyl, Avalox what can I take? Because of these allergies most doctors just put me on a zpack problem with that is I have been on it so many times that it isnt as effective as it should be. I know I can take levaquin but I was wonder if there are any other antibiotics that I can take?
