What antiemetic to NEVER give in palliative care?
ondansetron
antiemetic for metabolic causes (hypercalcaemia)/renal failure/opioid causes in palliative care
haloperidol
antiemetic for gastric stasis & functional bowel obstruction (bowel working) in palliative care
metoclopramide
OR
domperidone
(prokinetics - promote movement)
antiemetic for mechanical bowel obstruction (bowel not working) /raised intracranial pressure (brain tumour)/ motion sickness in PC
cyclizine
antiemetic if all others have failed in PC
levomepromazine

DISCONTINUE
- statins
- alendronic acid etc.
- laxatives
- diuretics

(to alt route - SC)
RX
- PRN meds for anticipated Sx for SC admin
anticipatory med for pain 1st, 2nd & 3rd line
- morphine = 1st line
- oxycodone - morphine not tol/renal impairment, can use GFR 10-30

problem with alfentanil
- very short half life
- needs to be Rx with oxycodone for BT pain
