Lithium

Meet the patient

A 58-year-old woman, twelve stable years on lithium, is brought to ED by her son. Four days of vomiting and diarrhoea after a family barbecue. She has been taking ibuprofen for the aches, and her GP started ramipril last month. She is drowsy, dysarthric, and her hands have a coarse, flapping tremor that was not there last week.[6][11][12]

Nobody changed her lithium dose. Nothing about her prescription is wrong on paper. Three ordinary events — dehydration, an over-the-counter anti-inflammatory, and a new antihypertensive — quietly raised her lithium while everyone watched the psychiatry.[11][12]

That is the exam question in one patient: lithium harms people through clearance, not through prescribing errors. Everything below exists to catch that.[6][11][12]
