This medicine may make you sleepy. If this happens, do not drive or use tools or machines. Which medicine is this?

• A. Sumatriptan
• B. Paracetamol
• C. Ibuprofen
• D. Furosemide

Answer: (A)

Drowsiness is a known side effect of this medicine, so it can affect your ability to drive or operate machinery. This drug is used to treat an acute migraine attack by targeting serotonin receptors, which can relieve symptoms but also cause dizziness or sleepiness in some people. If you notice you feel sleepy after taking it, avoid driving or using tools until you’re fully alert again.

Other options on the list are less commonly associated with drowsiness as a primary adverse effect. Paracetamol and ibuprofen are typically chosen for pain or fever and don’t usually cause sedation in the same way, while furosemide mainly causes increased urination and electrolyte changes rather than sleepiness. If you’re ever unsure, check patient information leaflet or ask a healthcare professional about how a specific medication may affect alertness.
