In brief: Sensitivity

We do not know why a specific substance, drug or product will cause an allergic reaction in a given person.
It is obviously a sensitivity of their immune system and of course requires exposure to the agent which in your case was erythromycin.

It is also important to differentiate between an allergy and a reaction like diarrhea or upset stomach which usually is not allergic.
