This can be iatrogenic due to drugs such as morphine sulphate, NSAIDs or anti-depressants, or due to biochemical abnormalities such as uraemia, jaundice, or hypercalcaemia. All these affect the chemoreceptor trigger zone in the brain to produce nausea and or vomiting.

Treat reversible causes where possible



Drug of choice: Haloperidol 2.5-5mg sc. initially then 3-5mg orally as single dose. This may be combined with cyclizine 75-150mg over 24 hours in a syringe driver to maximise response.

Second line: Levomepromazine 12.5–25mg nocte or 12.5-25mg over 24hours subcutaneously in a syringe driver.
