Correct answer: C — Treat with fast-acting carbohydrate and review meal patterns

Gliclazide can cause hypoglycaemia, especially when meals are missed. Symptoms with glucose 3.4 mmol/L should be treated with fast-acting carbohydrate, followed by longer-acting carbohydrate if needed. The patient should be counselled on regular meals and driving precautions. Recurrent episodes need prescriber review.
