Loratadine is best described as a medication that is typically taken how?

• A. Works only for acute symptoms
• B. Taken daily to be effective
• C. Requires prescription
• D. Not effective for seasonal allergies

Answer: (B)

Loratadine is a second‑generation antihistamine that blocks peripheral H1 receptors, preventing histamine from causing the classic allergy symptoms. Because allergic reactions to environmental triggers happen repeatedly, steady receptor blockade is most effective when the drug is taken daily, providing continuous symptom control rather than waiting for a single flare to appear. Its long-acting nature supports once‑daily dosing, and it’s commonly available without a prescription, making daily use practical for ongoing seasonal allergies. Saying it’s only for acute symptoms or not effective for seasonal allergies isn’t accurate, and requiring a prescription isn’t typically the case for loratadine.
