A member asked:
My daughter is allergic to penicillin and to cefzil--is this common?
A doctor has provided 1 answer
Yes: The two antibiotics share a common structure that can trigger an allergic response to both. There are some people that are allergic to one but not the other.It is all in how the individual's system reacts to taking the med.Thankfully there are other abx that share no common structures to these 2 that could be used if needed.
