Which prednisone tablet strength is not available according to the listed options?

• A. 2.5 mg
• B. 5 mg
• C. 10 mg
• D. 25 mg

Answer: (D)

Prednisone tablets are manufactured in standard strengths that fit common dosing regimens. The usual single-tablet strengths you’ll see stocked are 1 mg, 2.5 mg, 5 mg, 10 mg, 20 mg, and 50 mg. Among the options given, 25 mg isn’t a standard single-tablet strength. If a patient needs 25 mg, a clinician would typically prescribe 20 mg plus 5 mg (taken together) rather than using a 25 mg tablet, because that combination is simpler and more consistent with how these tablets are manufactured and dispensed. The other listed strengths are established, readily available options, whereas 25 mg as a standalone tablet isn’t commonly produced.
