How To Take IDEOS ?

Instructions for proper use:

  • Oral route.

how does IDEOS work?

Calcium carbonate

  • In the gastric environment, calcium carbonate releases the calcium ion, depending on the pH.
  • Calcium is mainly absorbed in the upper part of the small intestine.
  • The rate of absorption from the gastrointestinal tract is in the order of 30 percent of the ingested dose.
  • Calcium is eliminated through sweat and gastrointestinal secretions.
  • Urinary calcium is dependent on glomerular filtration and the rate of tubular reabsorption of calcium.

Vitamin D3

  • Vitamin D 3 is absorbed in the intestine and transported by protein bonds in the blood to the liver (first hydroxylation) and to the kidney (second hydroxylation).
  • Non-hydroxylated vitamin D 3 is stored in reserve compartments such as fatty and muscle tissue.
  • Its plasma half-life is of the order of a few days. It is eliminated in the faeces and urine.

How To Store IDEOS ?

  • Keep this medication out of the sight and reach of children.
  • The cap contains small granules of silica gel to absorb moisture.

IDEOS Interactions

Combinations subject to precautions for use


  • Risk of arrhythmia. Oral administration of calcium combined with vitamin D increases the toxicity of digitalis.
  • Strict medical supervision and, if necessary, an ECG and serum calcium monitoring are necessary.


  • It is advisable to respect an interval of at least two hours, before or after taking calcium (risk of reduced gastrointestinal absorption of bisphosphonates).

Thiazide diuretics

  • Monitoring of serum calcium is recommended (decrease in urinary excretion of calcium).

Oral tetracyclines

  • It is advisable to respect an interval of at least two hours before or after taking calcium (possible decrease in the absorption of tetracyclines).
  • In case of additional administration of vitamin D in high dose, a weekly control of calciuria and calcemia is essential.

Iron salt, zinc

  • It is advisable to respect an interval of at least two hours, before or after taking calcium (risk of reduced gastrointestinal absorption of iron salt or zinc).


  • Risk of reduction by 60 to 70% of the bioavailability of strontium when administered in combination with products containing calcium.
  • It is recommended to avoid taking calcium before or after taking products containing strontium.


  • Risk of reduced gastrointestinal absorption of estramustine. It is advisable to respect an interval of at least two hours before or after taking calcium.

Thyroid hormones

  • Risk of reduced gastrointestinal absorption of levothyroxine. It is advisable to respect an interval of at least two hours before or after taking calcium.


  • Treatment with orlistat may possibly decrease the absorption of vitamin D.


  • Possibility of interactions with foods containing oxalic acid (spinach, rhubarb, sorrel, cocoa, tea, etc.), phosphates (cold meats, ham, sausages, processed cheeses, dessert creams, cola drinks, etc.) or phytic acid (whole grains, pulses, oil seeds, chocolate…).
  • This is why it is recommended to take meals containing this type of food a little before or a little after the ingestion of the product.

Warnings and Precautions

  • In the event of prolonged immobilization accompanied by hypercalciuria and / or hypercalcemia, the Vitamin D-Calcium treatment should only be used upon resumption of mobilization.
  • In the event of long-term treatment, it is justified to control serum calcium, calciuria and renal function (creatinine clearance). It is advisable to reduce or temporarily interrupt the treatment if the calciuria exceeds 7.5 mmol / 24 h (300 mg / 24 h). This monitoring is particularly important in the elderly in the event of combined treatment with digitalis or thiazide diuretics (see section Interactions with other medicinal products and other forms of interactions ) and in patients frequently prone to renal stones. In case of hypercalcaemia or kidney function problems, the dose should be reduced or treatment interrupted.
  • In case of treatment combined with bisphosphonates or tetracyclines: see section Interactions with other medicinal products and other forms of interactions .
  • Take into account the dose of vitamin D. This product already contains vitamin D, the additional administration of vitamin D or calcium must be done under strict medical supervision, with weekly monitoring of calcium and calciuria.
  • The product should be prescribed with caution in patients with sarcoidosis due to a possible increased metabolism of vitamin D in its active form. In these patients, serum calcium and calciuria should be monitored.
  • The product should be prescribed with caution in patients with renal insufficiency with monitoring of the phosphocalcic balance. The risk of soft tissue calcification should be taken into consideration. In patients with severe renal impairment, vitamin D 3 as cholecalciferol is not metabolized by the normal route and other forms of vitamin D 3 should be used.
  • This drug contains sorbitol. Its use is not recommended in patients with fructose intolerance (a rare hereditary disease).
  • This medicine contains sucrose. Its use is not recommended in patients with fructose intolerance, glucose-galactose malabsorption syndrome or sucrase-isomaltase deficiency.
  • This medicine is not indicated for children or adolescents.


This product can be used during pregnancy and lactation. However, the daily dose should not exceed 1500 mg of calcium and 600 IU of vitamin D3 .


During pregnancy, cholecalciferol overdose should be avoided:

  • overdoses of vitamin D during gestation have had teratogenic effects in animals,
  • Pregnant women, overdoses in vitamin D should be avoided as permanent hypercalcaemia can result in children physical and mental retardation, aortic stenosis or retinopathy supravalvar.
  • However, several children were born without malformation after administration of very high doses of vitamin D3 for hypoparathyroidism in the mother.

Feeding with milk

  • Vitamin D3 and its metabolites pass into breast milk. This must be taken into account when administering vitamin D to children.
