contraindications for Promethazine (Phenergan®), Prochlorperazine (Compazine®)
“Both: AVOID in elderly.
Compazine: BBW: elderly for dementia-related psychosis! Has anticholinergic effects in addition to the Dopamine antagonism. AVOID in altered consciousness,in addition to other sedative/opioids as further sedation and respiratory decline can occur additively
Phenergan: avoid IV, IM due to tissue necrosis”
