Which medication listed is a beta-blocker that can cause nightmares as a side effect?

• A. Propranolol
• B. Diazepam
• C. Amlodipine
• D. Paracetamol

Answer: (A)

Nightmares can be a side effect of certain drugs that affect the brain, particularly beta-blockers that enter the central nervous system. Propranolol is a non-selective beta-blocker that readily crosses into the brain, so it’s more likely to cause CNS-related effects like nightmares. The other medications listed are not beta-blockers: diazepam is a benzodiazepine with sedative effects but isn’t typically linked to nightmares as a hallmark side effect; amlodipine is a calcium channel blocker; paracetamol is an analgesic/antipyretic with no beta-blocking action. So propranolol best fits the description.
