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.
- 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.
- Euglycaemia needs to be maintained for 12 hours off an infusion before the patient is medically cleared
- Paediatric doses = 1 microgram/kg as a bolus IV of SC and also 1 microgram/kg/hour as an infusion IV.
