1. Several bodies make recommendations for defined amounts of daily calcium for different physiological groups. Those of the National Osteoporosis Society (2001) are reproduced below with more detail available in the full document by clicking here.

COMA calcium recommendations

Age RNI*                   
0 - 12 months (breast fed only) 525 mg

2. Calcium supplementation is no substitute for oestrogen in preventing perimenopausal bone loss. (See section 6.4 for suitable hormone replacement therapy). Hypercalcemia and Hypercalciuria

Etelcalcetide  - see NICE TA 448

This is included for initiation by renal specialists for treatment of refractory secondary hyperparathyroidism in patients with end-stage renal disease or maintenance dialysis therapy (as per NICE guidance, TA117). Also available for primary hyperparathyroidism (click here for shared care). Agreed criteria are:

1. The treatment of acute hypercalcaemia (calcium >3.0mmol/l) due to Primary Hyperparathyroidism, when parathyroidectomy is contraindicated or not clinically appropriate , and will avoid the need for further admission to hospital

2. The treatment of hypercalcaemia (Ca >3.0mm/l) in patients who are significantly symptomatic and awaiting surgery.

3. Etelcalcetide is recommended as an option for treating secondary hyperparathyroidism in patients with chronic kidney disease on haemodialysis, only if treatment with a calcimimetic is indicated but cinacalcet is not suitable. Magnesium 

Co-magaldrox mixture (Maalox) – first-line (except for pts with short-bowel syndrome)
Magnesium aspartate (Magnaspartate) powder for oral solution – for pts with short-bowel syndrome
Magnesium sulphate injection

Phosphate-Sandoz tablets effervescent
Potassium dihydrogen phosphate injection.
Sodium dihydrogen phosphate


Oral phosphate supplements may be required in addition to vitamin D in a small minority of patients with hypophosphataemic vitamin D-resistant rickets. Diarrhoea is a common side efecct and should prompt a reduction in dosage.

All phosphate binding drugs are now GREEN after specialist initiation

Aluminium hydroxide mixture, capsules - 'Alu-Cap'
Calcium acetate tablets
Calcium carbonate + glycine - 'Titralac' tablets
Calcichew tablets
Lanthanum tablets (hospital prescribing only)
Sevelamer tablets, sachets
Sucroferric oxyhydroxide 

Phosphate binders for the long-term treatment of hyperphosphataemia in patients on dialysis, see link.

9.5.4 Zinc

Zinc sulphate MR spansules, effervescent tablets


The only definite indication for zinc supplementation is zinc deficiency. There is some evidence to suggest it may be useful in the prevention and treatment of pressure sores and treatment of burns.
