Calpol :-


250 mg or 500 mg tablet:

This is used for the treatment or prevention of calcium depletion in patients in whom dietary measures are inadequate.
Conditions that may be associated with calcium deficiency include

Calcium Carbonate may interfere with the absorption of concomitantly administered tetracycline preparations and in chronic renal failure modification of vitamin D therapy may be required to avoid hypercalcaemia when Calcium Carbonate is used as the primary phosphate binder.

• hypoparathyroidism,
• achlorhydria,
• chronic diarrhea,
• vitamin D deficiency,
• steatorrhea,
• pregnancy and
• lactation,
• renal failure,
• pancreatitis,
• menopause,
• sprue,
• alkalosis, and
• hyperphosphataemia.


Calcium Carbonate is being used increasingly often to treat hyperphosphataemia in chronic renal failure as well as those on continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis.

Calcium Carbonate containing preparations can provide short-term relief of dyspeptic systems but are no longer recommended for long-term treatment of peptic ulceration.

Calcium Carbonate may enhance the cardiac effects of digoxin and other cardiac glycosides, if systemic hypercalcaemia occurs.

Many patients are unable to tolerate sufficient doses for complete phosphate control and require additional measures such as stringent dietary phosphate restriction or relatively small doses of aluminium hydroxide.



250 mg or 500 mg tablet: Calcium Carbonate is always used orally and when used as an antacid the recommended doses for adults are equivalent to 540-2000 mg Calcium Carbonate per day, doses for children being half of those for adults.

1000 mg tablet: This is indicated for the management of conditions associated with hyperidity and for fast relief of acid indigestion, heartburn, sour stomach and upset stomach.

1000 mg tablet: 2000 – 3000 mg tablet when symptoms occur; may be repeated hourly if needed or as directed by the physician.


In chronic renal failure the doses used vary from 2.5-9.0 gm Calcium Carbonate per day and need to be adjusted according to the individual patient.

To maximize effective phosphate binding in this context the Calcium Carbonate should be given with meals.

In pregnancy and lactation the recommended daily dose of calcium is 1200-1500 mg.


As a dietary supplement, such as for the prevention of osteoporosis, 1250-3750 mg Calcium Carbonate (500-1500 mg calcium) daily is recommended in general, but again this will need to be tailored to the individual patient depending on any specific disease such as Calcium deficiency, malabsorption or parathyroid function.
