Allergic reaction continued?

Patient: Hello,I have a quick question I just had strep throat last week and saw an on call doctor who put me on biaxin, turns out 5 days later i had an allergic reaction (hives all over my body) to the drug. But now again five days later after stopping that pill i have severe diaherea. Is this just the drug coming out of my system?
