Drug Allergy
Drug Allergy Overview
Every medication out there carries a risk of triggering an allergic reaction. Penicillin, along with other antibiotics in the same family, leads the list as a frequent culprit.
Alongside these, drugs like aspirin and ACE inhibitors also often set off allergic responses in some people.
So, what sets drug allergies apart? They don’t behave like ordinary side effects. The immune system launches an attack, mistaking the drug for a harmful invader. These reactions can look different for everyone, too—some break out in hives, others struggle with swelling or difficulty breathing.
