I am allergic to erythromycin. My doc prescribed the Z-pak, family member of erythromycin. He states it is not a derivitive of erythromycin. I almost died taking erythromycin. I just took a dose, how long would it take for an allergic reaction to it,He is pretty sure I won't get one. I am just curious. ------
