4.3 Contraindications

Addison's disease, adrenal insufficiency, acute or chronic renal disease, oliguria, anuria and patients with hyperkalaemia. The intravenous infusion of glucose solutions may also be hazardous in patients with impaired hepatic function.

4.4 Special warnings and precautions for use

Caution should be exercised in the volume and rate of infusion since fluid overload and hyperkalaemia may compromise cardiac function. Before administering potassium by the intravenous route a non-potassium containing hydrating solution should be administered to ensure adequate renal function.

The label states: Do not use unless the solution is clear and free from particles. Rapid infusion may be harmful.
