Which medications may contain caffeine?

• A. Appetite suppressants, analgesics, allergy/cold relief tablets
• B. Antibiotics and antacids
• C. Insulin and metformin
• D. Antiplatelets and statins

Answer: (A)

Caffeine is sometimes added to certain nonprescription formulations to provide a mild stimulant effect or to boost pain relief. In analgesics, caffeine can enhance the effectiveness of the pain reliever and is also used to help with migraines. In appetite suppressants, caffeine’s stimulant properties support increased energy and reduced appetite. In allergy or cold relief tablets, caffeine may be included to counteract drowsiness from antihistamines or to give a mild alertness boost.

That’s why this group fits best: appetite suppressants, analgesics, and allergy/cold relief tablets. Antibiotics and antacids, insulin and metformin, and antiplatelets and statins don’t typically contain caffeine, as their formulations focus on treating infections, acid symptoms, diabetes, or cardiovascular risk without relying on a stimulant additive.
