Dr. Paul Williams answered

Specializes in Allergy and Immunology

Not "allergy": Caffeine acts more like a chemical and not l ike an allergen, it does not cause immune reactions, but as a chemical has numerous effects on the cardiac and nervous systems such as jitteriness, nervousness, increased intestinal motility, and so on.
