Phentolamine

Key points  

  • We recommend to consult your poison centre with the use of this antidote.
  • Except for treatment of vasoconstriction secondary to an extravasation of vasoconstrictor agents, phentolamine is rarely a first-line treatment and should only be considered following an inadequate response to initial treatments (e.g. benzodiazepines, nitroglycerin).
