No, : No, you should not take the cephalexin. Cephalexin is related to amoxicillin, and if you have had an allergic reaction to amoxicillin, this would be a risk. Please call the emergency department and ask them to call in an alternative prescription that is not related to amoxicillin. It is good that you were observant of this and asked this question.

Depends: Cephalexin is very close structurally to penicillin. It depends on what your allergic reaction to pcn is. If it is anaphylaxis, then stay away. If it is mild, then call your primary doctor since there is no guarantee you will have a reaction but better to be safe.
