For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Profound hypotension and loss of consciousness have been reported when apomorphine is given with ondansetron, and the apomorphine label contraindicates 5-HT3 antagonists. Palonosetron is a related 5-HT3 antagonist, so the same risk is assumed by class.
What this interaction means in plain words
Apomorphine and Netupitant-palonosetron are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Apomorphine belongs to Central Nervous System; Netupitant-palonosetron belongs to Gastrointestinal Tract.
Why it happens
The mechanism is not established; it is thought to involve a pharmacodynamic effect of 5-HT3 antagonism on apomorphine-related hypotension.
What to do
Avoid combining apomorphine with 5-HT3 antagonists. Use an antiemetic such as trimethobenzamide for apomorphine-related nausea.
