Question 1 of 5

How does an antihistamine work?

Correct Answer: A

Rationale: The correct answer is A: By blocking the effects of histamine in the body. Antihistamines work by binding to histamine receptors, preventing histamine from exerting its effects. Histamine is released during allergic reactions, leading to symptoms like itching, sneezing, and swelling. By blocking histamine, antihistamines alleviate these symptoms.
Choice B is incorrect because antihistamines do not directly reduce inflammation.
Choice C is incorrect because antihistamines do not increase histamine production; they work by the opposite mechanism.
Choice D is incorrect because antihistamines do not stimulate the immune system; they modulate the effects of histamine.
