Correct answer: A — Take it in the morning to reduce night-time urination

Furosemide causes diuresis, so morning dosing reduces nocturia and sleep disturbance. Some patients on twice-daily dosing may take the second dose in the early afternoon rather than late evening. Extra salt or routine potassium supplements should not be suggested unless clinically indicated. The pharmacist should also advise on dizziness and monitoring.
