The Risk of Hyperglycaemia with Systemic Glucocorticoids

Prescriber Update 39(1): 3
March 2018

Key Messages

  • Systemic glucocorticoids can cause hyperglycaemia in both diabetic and non-diabetic patients.
  • Monitor the blood glucose levels of diabetic patients taking glucocorticoids.
  • Non-diabetic patients treated with systemic glucocorticoids should be asked if they are experiencing any symptoms of hyperglycaemia.

Medsafe was recently notified of a case where a patient was treated with high dose dexamethasone who developed diabetic ketoacidosis requiring hospitalisation.

Healthcare professionals are reminded that systemic glucocorticoids, including dexamethasone, can cause hyperglycaemia (severe enough to cause ketoacidosis) in both diabetic and non-diabetic patients1,2.

In non-diabetics, effects on blood glucose levels are dose-dependent usually with a mild increase in fasting glucose levels and a greater increase in postprandial values2. It is important to ask non-diabetic patients if they are experiencing any symptoms of hyperglycaemia during treatment with systemic glucocorticoids.

Diabetic patients may experience difficulties with glycaemic control while taking glucocorticoids2. Regular monitoring of blood glucose levels is important during treatment with glucocorticoids, and dose adjustments for insulin or oral hypoglycaemic agents may be required.

Medsafe is working with pharmaceutical companies to ensure all data sheets for systemic glucocorticoids include information on the risk of hyperglycaemia. Please continue to report any adverse reactions to medicines to CARM.
