Potential hazards of parenteral administration: 
  • Bradycardia (Antidote: atropine), tachycardia, premature ventricular contractions, chest pains
  • Headache, restlessness, anxiety, insomnia
  • Hypersensitivity reactions (Injection contains metabisulfite that may cause an allergic reaction in susceptible individuals)
  • Avoid extravasation as it may cause sloughing and necrosis (Treatment: phentolamine). If extravasation occurs, click HERE for treatment guidelines.   
Notes: 
  • Check blood pressure every 2 minutes until desired level, then every 5 minutes.  DO NOT leave patient unattended.  DO NOT discontinue abruptly because of danger of sudden drop in blood pressure.
  • 1 mL solution = 2 mg norepinephirne bitartrate = 1 mg norepinephrine base
  • Monitor BP, HR, urine output, peripheral perfusion
