Assessment and treatment
Identify and treat the underlying causes of hypomagnesaemia.
Correct any other electrolyte disturbances. Hypomagnesaemia is often associated with hypocalcaemia and hypokalaemia.
The dose, dosing schedule and duration of treatment will depend on your patient’s serum magnesium level and symptoms.
Lower doses may be required in renal impairment due to the risk of hypermagnesaemia.
In general, in mild hypomagnesaemia then use oral magnesium replacement
- give intravenous (IV) magnesium sulfate in a hospital setting if the oral route is not available
Seek expert advice.
Treatment:
- oral magnesium salts - magnesium glycerophosphate least likely to cause diarrhoea
- parenteral magnesium sulphate
