Correct answer: D — Aim for the lowest effective dose, balancing adverse effects against undertreatment

The correct answer is D. NICE advises aiming for the lowest effective dose when choosing the initial dose and subsequent increases in people with learning disabilities. Prescribers should consider adverse effects and the person’s possible difficulty recognising or communicating them, while avoiding subtherapeutic dosing that leaves depression inadequately treated. NICE does not mandate a universally lower-than-usual starting dose, a fixed dose reduction or slower titration for every patient. Learning disability does not contraindicate SSRIs or antidepressant treatment generally, and tricyclic antidepressants are not preferred solely because a person has a learning disability. Treatment should otherwise follow the relevant NICE guideline for depression, with individualised monitoring and review.
