Octreotide

Long-acting synthetic octapeptide analogue of somatostatin useful in the control of sulfonylurea-induced hypoglycaemia (BSL <4 mol/L) either from overdose or an iatrogenic source. It is also useful in hypoglycaemia induced from Quinine.


Administration

  • Administer 50 micrograms IV, then…..
  • Commence an infusion at 25 micrograms/hour. Dilute 500 micrograms of octreotide in 500ml of 0.9% saline and infuse at 25 ml/hour
  • Alternatively give 100 micrograms SC or IM every 6 hours, although break through hypoglycaemia may occur.
  • Euglycaemia is usually maintained while on the infusion but if it dose occur correct with 50% dextrose and double the infusion rate.
