Correct answer: CAdditive QT prolongation risk

This scenario assesses Methadone citalopram in a UK pharmacy practice context. Methadone and citalopram can both prolong QT interval. The best answer is Additive QT prolongation risk because it addresses the principal clinical, legal or safety issue before routine supply. The other options are less appropriate because they either miss the key risk, delay necessary review, or would not meet expected BNF, NICE, MEP, MHRA or GPhC practice standards.
