General supportive measures

Important general supportive measures include:

1. Removal of calcium from parenteral feeding solutions and fluids
2. Discontinuation of the use of oral calcium supplements and calcium containing medications, such as antacids
3. Discontinuation of medications that may independently lead to hypercalcaemia e.g. lithium, calcitriol, vitamin D and thiazides
4. Discontinuation of medications that may exacerbate symptoms of hypercalcaemia, such as sedatives and hypnotics.

Further measures can include, if possible, an increase in the weight-bearing mobility of the patient, which theoretically will slow the loss of skeletal calcium associated with immobility, as well as helping to protect the patient from pressure sores, infections, delirium and general deconditioning.
