Octreotide Hypoglycaemia: 3 case reports
Three patients with acromegaly received SC octreotide 100 ~g tid . After 1 month 's therapy patients were evaluated for the effectiveness of treatment.
Sudden symptoms of hypoglycaemia developed in 2 patients and all 3 were shown to have depressed serum glucose levels, despite a controlled diet. It was demonstrated that insulin levels were depressed 1 hour after octreotide administration , with gradual resolution .
The authors concluded that " , , one has to bear in mind the possibility of hypoglycaemia, when treating acromegalic patients with Sandostatin [octreotlde ]',

Induction of severe hypoglycaemia in patients with pancreatic insulinomas: 2 case reports
Long·acting somatostatin analogues have been used in patients with insulinomas to control insulin·induced hypoglycaemia. A 77·year·old woman (patient 1) and a 50-year·old man (patient 2) experienced severe hypoglycaemic episodes which required hospitalisation. Both patients were diagnosed with pancreatic insulinoma.
The ability of octreotide to control insulin-induced hypoglycaemia was assessed in these patients. Prior to breakfast , both patients received SC octreotide ('Sandostatin ') 50~g ; severe hypoglycaemia occurred in both patients . The next day, patient 2 received an additional dose of octreotide after breakfast with no hypoglycaemia observed .
Following octreotide studies a 3 x 3 x 2cm tumour was found and removed from the tail of the pancreas in patient 1 and a 1 cm diameter tumour was removed from the head of the pancreas in patient 2. Metastases were observed in patient 1 and she was treated with streptolocin , with complete remission. Postsurgery, glucose and insulin levels returned to normal in patient 2.
Thus, " , , in patients with an insulinsecreting tumour, treatment with the long-acting somatostatin analogue octreotide may be associated with a transient decrease in serum glucose levels, This may result in clinically important hypoglycemia ',
