When is the best time to take a sulfonylurea?

• A. In the morning with food
• B. Before bedtime
• C. After intense exercise
• D. Between meals

Answer: (A)

The timing concept is that sulfonylureas boost insulin release, so taking them with a meal helps match the insulin increase to the rise in blood glucose after eating. Placing the dose with the morning meal aligns the drug’s effect with breakfast, improving post-meal glucose control and reducing the risk of hypoglycemia if a meal is missed. Taking the drug at other times—before bed, after exercise, or between meals—can leave a mismatch between insulin action and glucose availability, increasing the chance of low blood sugar during fasting or overnight periods.
