Statement 1: When the antibody combines with allergen, it releases histamine.
Statement 2: Antihistamine causes allergic reactions.
Statement 1 is true and statement 2 is false
When a special kind of antibody combines with an allergen, histamine is released. The histamine then causes the allergic reaction. Whereas, antihistamines are the drugs that prevent allergic reactions though they do not cure the allergy completely.
