A 55-year-old man has experienced four lifetime episodes of depression. He previously developed a further depressive episode 3 months after completing a gradual sertraline taper. He has again achieved remission with sertraline and asks how long he should continue taking it. According to current NICE NG222, which approach is most appropriate?

Correct answer: AContinue sertraline for relapse prevention, review at least every 6 months, and agree the ongoing duration through shared decision-making

C is correct. His recurrent episodes and previous recurrence after tapering indicate a higher risk of relapse. NICE NG222 does not prescribe a universal minimum of 2 years or recommend indefinite treatment solely because four episodes have occurred. For a higher-risk person who remitted with an antidepressant, NICE advises considering continuation at the dose that produced remission, unless there is a reason to reduce it. Treatment should be reviewed at least every 6 months, assessing mood, adverse effects, relapse risks and the person's preference about continuing. A and B impose fixed stopping dates not specified by NG222; 6 months is a typical minimum treatment period but is not an automatic stopping point in high-risk relapse prevention. D incorrectly converts evidence extending up to 2 years into a fixed duration recommendation. E disregards his substantial relapse risk.
