Indications

Gastroesophageal Reflux Disease Dyspepsia Diarrhea Calcium Deficiency

Elemental Forbon tablet (250 mg or 500 mg) is used to treat or prevent calcium depletion in patients whose diet alone does not supply enough calcium. Conditions that may cause calcium deficiency include hypoparathyroidism, achlorhydria, chronic diarrhea, vitamin D deficiency, steatorrhea, sprue, pregnancy and lactation, menopause, pancreatitis, renal failure, alkalosis, and hyperphosphataemia. Forbon is being used increasingly to treat hyperphosphataemia in chronic renal failure, including in patients on continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis. Many patients cannot tolerate doses high enough for complete phosphate control and need additional measures such as strict dietary phosphate restriction or relatively small doses of aluminium hydroxide. Preparations containing Forbon can give short term relief from dyspeptic symptoms but are no longer recommended for long term treatment of peptic ulceration. The 1000 mg tablet of Elemental Forbon is indicated for managing conditions associated with hyperacidity and for fast relief of acid indigestion, heartburn, sour stomach, and upset stomach.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Calcium carbonate reacts with stomach acid to form a salt and water. The reaction usually given for calcium carbonate is CaCO3 + 2HCl = CaCl2 + H2O + CO2. Two grams of calcium carbonate will readily bring 100 ml of hydrochloric acid up to a pH above 6. As the stomach becomes less acidic, the activity of pepsin in the gastric secretion goes down. Up to 30% of the oral calcium load may be absorbed.

Pregnancy & Breastfeeding

Calcium carbonate has been widely used during pregnancy, either as an oral calcium supplement or as an antacid. It can also be used by women who are breastfeeding.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: 250 mg or 500 mg tablet: Calcium Carbonate is always taken by mouth. When it is used as an antacid, the recommended dose for adults ranges from 540 mg to 2000 mg of Calcium Carbonate per day, with children given half the adult dose. As a dietary supplement, such as for preventing osteoporosis, the general recommendation is 1250 mg to 3750 mg of Calcium Carbonate (500 mg to 1500 mg of calcium) daily, though this should be tailored to the individual patient depending on any specific condition such as calcium deficiency, malabsorption, or parathyroid problems. During pregnancy and breastfeeding, the recommended daily dose of calcium is 1200 mg to 1500 mg. In chronic renal failure, doses of Calcium Carbonate used range from 2.5 gm to 9.0 gm per day and need to be adjusted for the individual patient. To get the most effective phosphate binding in this situation, Calcium Carbonate should be taken with meals. 1000 mg tablet: 2000 mg to 3000 mg when symptoms occur; this may be repeated hourly if needed, or as directed by the physician.
