Question

which of the following medication classifications should be used for a patient who is experiencing seasonal allergies? antihypertensives antihistamines diuretics antipyretics

Explanation:

• Antihypertensives: These medications are used to treat high blood pressure. They have no direct relation to treating seasonal allergies.
• Antihistamines: Seasonal allergies are often caused by an over - reaction of the immune system, which releases histamine. Antihistamines block the action of histamine, thus relieving allergy symptoms like sneezing, itching, and runny nose.
• Diuretics: Diuretics are used to increase urine output. They are mainly used in conditions like heart failure (to reduce fluid overload) and hypertension (to a lesser extent for blood pressure control). They do not address allergic reactions.
• Antipyretics: Antipyretics are used to reduce fever. They work on the hypothalamic thermoregulatory center. They have no role in treating the underlying cause of seasonal allergies.

Answer:

B. Antihistamines
