No dose adjustment is required
Accrete D3 One a Day Chewable tablets must not be used in patients with severe renal impairment (see section 4.3).
During pregnancy the daily intake should not exceed 1,500 mg of calcium and 600 I.U. of vitamin D3. Therefore, the daily dose must not exceed half a tablet (see section 4.6).
Accrete D3 One a Day Chewable tablets must not be used in children and adolescents below 18 years of age (see section 4.3).
Method of administration
Accrete D3 One a Day Chewable tablets can be taken at any time, with or without food. The chewable tablets should be chewed and swallowed.
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
- Hypercalciuria and hypercalcaemia and diseases and/or conditions, which lead to hypercalcaemia and/or hypercalciuria (e.g. myeloma, bone metastases, primary hyperparathyroidism, prolonged immobilisation accompanied by hypercalciuria and/or hypercalcaemia).
- Hypervitaminosis D
- Severe renal impairment (glomerular filtration rate <30 ml/min/1.73 m2)
- Use in children or adolescents below 18 years of age due to the high content of vitamin D in this medicinal product
During long-term treatment, serum calcium levels should be followed and renal function should be monitored through measurements of serum creatinine. Monitoring is especially important in geriatric patients on concomitant treatment with cardiac glycosides or thiazide diuretics (see section 4.5) and in patients with a high tendency to calculus formation. In case of hypercalcaemia or signs of impaired renal function, if urinary calcium excretion exceeds 300 mg/24 hours (7.5 mmoles/24 hours) the dose should be reduced or the treatment discontinued.
Calcium/cholecalciferol should be used with caution in patients with increased risk of hypercalcaemia or signs of impairment of renal function and the effect on calcium and phosphate levels should be monitored. The risk of soft tissue calcification should be taken into account. In patients with severe renal insufficiency, vitamin D in the form of cholecalciferol is not metabolised normally and other forms of vitamin D should be used (see section 4.3).
Accrete D3 One a Day Chewable tablets should be prescribed with caution to patients suffering from sarcoidosis, due to the risk of increased metabolism of vitamin D into its active form. These patients should be monitored with regard to the calcium content in serum and urine.
Accrete D3 One a Day Chewable tablets should be used cautiously in immobilised patients with osteoporosis due to increased risk of hypercalcaemia.
The content of vitamin D (880 IU) in Accrete D3 One a Day Chewable tablets should be considered when prescribing other medicinal products containing vitamin D. Additional doses of calcium or vitamin D should be taken only under close medical supervision. In such cases it is necessary to monitor serum calcium levels and urinary calcium excretion frequently.
A potential additional ingestion of calcium and alkaline products (due to the intake of nutrients, fortified foods or other medicinal products) should be considered. A milk-alkali syndrome (Burnett-Syndrome), i.e. hypercalcaemia, metabolic alkalosis, renal failure and soft tissue calcification can occur if high doses of calcium are taken concomitantly with absorbable alkali medicinal products (like carbonate).
Co-administration with tetracyclines or quinolones is usually not recommended, or must be done with precaution (see section 4.5).
There have been literature reports alluding to possible increased absorption of aluminium with citrate salts. Accrete D3 One a Day Chewable tablets contains citric acid.
Calcium/cholecalciferol is contraindicated in children and adolescents below 18 years (see section 4.3).
Accrete D3 One a Day Chewable tablets contains sodium, aspartame, sorbitol, isomalt, sucrose and benzyl alcohol
This medicinal product contains less than 1 mmol sodium (23 mg) per chewable tablet, that is to say essentially 'sodium-free'.
This medicinal product contains 1.00 mg aspartame (E 951) in each chewable tablet. Aspartame is a source of phenylalanine which may be harmful for people with phenylketonuria.
This medicinal product contains up to 152.89 mg sorbitol (E 420) in each chewable tablet. Patients with hereditary fructose intolerance (HFI) should not take/be given this medicinal product.
It also contains isomalt (E 953) and sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicinal product. May be harmful to the teeth.
This medicine contains 0.02 mg benzyl alcohol in each chewable tablet. Benzyl alcohol may cause allergic reactions.
Thiazide diuretics reduce the urinary excretion of calcium. Due to increased risk of hypercalcaemia, serum calcium should be regularly monitored during concomitant use of thiazide diuretics.
Systemic corticosteroids reduce calcium absorption. Moreover the effect of vitamin D may be decreased. During concomitant use, it may be necessary to increase the dose of Accrete D3 One a Day Chewable tablets.
Concomitant treatment with rifaximin, phenytoin or barbiturates can decrease the effect of vitamin D because of metabolic activation.
Simultaneous treatment with orlistat, ion exchange resins such as cholestyramine or laxatives such as paraffin oil may reduce the gastrointestinal absorption of vitamin D. Therefore a time interval as long as possible between the intakes is recommended.
Oxalic acid (e.g. found in spinach and rhubarb) and phytic acid (e.g. found in whole cereals) may inhibit calcium absorption through formation of insoluble compounds with calcium ions. The patient should not take calcium products within two hours of eating foods high in oxalic acid and phytic acid.
Calcium carbonate may interfere with the absorption of concomitantly administered tetracycline preparations. For this reason, tetracycline preparations should be administered at least two hours before or four to six hours after oral intake of calcium.
Hypercalcaemia may increase the toxicity of cardiac glycosides during treatment with calcium and vitamin D. Patients should be monitored with regard to electrocardiogram (ECG) and serum calcium levels.
If a bisphosphonate, sodium fluoride or fluoroquinolones are used concomitantly, this preparation should be administered at least three hours before the intake of Accrete D3 One a Day Chewable tablets since gastrointestinal absorption may be reduced.
Calcium salts may decrease the absorption of iron, zinc or strontium ranelate. Consequently, the iron, zinc or strontium ranelate preparations should be taken at a distance of two hours from the calcium preparation.
Calcium salts may reduce the absorption of the estramustin or thyroid hormones. It is advised to take this medicinal product two hours after such medicinal products are administered.
Accrete D3 One a Day Chewable tablets can be used during pregnancy in case of a calcium and vitamin D deficiency. During pregnancy the daily intake should not exceed 1,500 mg of calcium and 600 I.U. of vitamin D3. Therefore, the daily dose must not exceed half a tablet.
High doses of vitamin D have been shown to have teratogenic effects in animal experiments.
In pregnant women, overdoses of calcium and vitamin D should be avoided, since prolonged hypercalcaemia has been sometimes associated with retardation of physical and mental development, supravalvular aortic stenosis and retinopathy in the child.
Accrete D3 One a Day Chewable tablets can be used during breast-feeding. Calcium and vitamin D3 pass into the breast-milk . This should be considered when giving additional vitamin D to the child.
No data available.
Calcium/cholecalciferol have no known influence on the ability to drive and use machines.

Special patient group
Patients with renal impairment are at increased risk for hyperphosphataemia, nephrolithiasis and nephrocalcinosis (see section 4.4).
Reporting of suspected adverse reactions:
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme (www.mhra.gov.uk/yellowcard) or search for MHRA Yellow Card in the Google Play or Apple App Store.
Overdose can lead to hypervitaminosis, hypercalciuria and hypercalcaemia. Symptoms of hypercalcaemia may include anorexia, dehydration, thirst, nausea, vomiting, constipation, abdominal pain, muscle weakness, fatigue, mental disturbances, polydipsia, polyuria, bone pain, nephrocalcinosis, renal calculi and in severe cases, cardiac arrhythmias. Extreme hypercalcaemia may result in coma and death.
Persistently high calcium levels may lead to irreversible renal damage, soft tissue calcification, vascular and organ calcification.
The milk-alkali syndrome of hypercalcaemia, alkalosis and renal impairment still occur in patients who ingest large amounts of calcium and absorbable alkali; it is not uncommon as a cause of hypercalcaemia requiring hospitalisation. The syndrome has also been reported in a patient taking recommended doses of antacids containing calcium carbonate for chronic epigastric discomfort, and in a pregnant woman taking high, but not grossly excessive, doses of calcium (about 3 g of elemental calcium daily). Metastatic calcification can develop.
The threshold for vitamin D intoxication is between 40,000 and 100,000 IU per day and for calcium intoxication is from supplementation in excess of 2000 mg per day, taken for several months, in persons with normal parathyroid function.
Treatment is essentially symptomatic and supportive.
Treatment of hypercalcaemia: The treatment with calcium and vitamin D must be discontinued. Treatment with thiazide diuretics, lithium, vitamin A, vitamin D and cardiac glycosides must also be discontinued (see section 4.5).
Rehydration, and, according to severity, isolated or combined treatment with loop diuretics (e.g. furosemide), bisphosphonates, calcitonin and corticosteroids should be considered. In patients with renal failure, hydration is ineffective and they should undergo dialysis. Serum electrolytes, renal function and diuresis must be monitored. In severe cases, ECG and CVP should be followed.
In the case of persistent hypercalcaemia, contributing factors should be excluded, e.g. primary hyperparathyroidism, malignancies, renal failure or immobilisation.
Depending on the degree of hypercalcaemia and on the patient's condition, e.g. in case of oligoanuria, haemodialysis (calcium-free dialysate) may be necessary.
Combination of calcium with other drugs, ATC code A12AX
Mechanism of action
Accrete D3 One a Day Chewable tablets is a fixed combination of calcium and vitamin D3. The high calcium and vitamin D3 concentration in each dose unit enables sufficient absorption of calcium with a limited number of doses. Vitamin D3 is involved in calcium-phosphorus metabolism. It allows the active absorption of calcium and phosphorus from the intestine and their uptake by bone. Supplementation with calcium and vitamin D3 corrects latent vitamin D deficiency and secondary hyperparathyroidism.
In a double-blind placebo controlled study of 18 months, including 3270 women aged 84 ± 6 and living in nursing homes, supplemented with cholecalciferol (800 IU/day) + calcium (1.2 g/day), a significant decrease in PTH secretion has been observed. After 18 months, the results of the intent to treat analysis showed 80 hip fractures in the calcium vitamin D group and 110 hip fractures in the placebo-group (p=0.004). So in the conditions of this study, the treatment of 1387 women prevented 30 hip fractures. After 36 months of follow-up, 137 women presented at least one hip fracture in the calcium-vitamin D group (n=1176) and 178 in the placebo group (n=1127) (p≤0.02).
30-40% of the ingested dose of calcium is absorbed, predominantly in the proximal part of the small intestine.Distribution and biotransformation
99% of the calcium in the body is concentrated in the mineral component of bones and teeth. The remaining 1% is present in the intra- and extracellular fluids. About 50% of the total blood-calcium content is in the physiologically active ionised form with approximately 5% being complexed to citrate, phosphate or other anions. The remaining 45% being bound to proteins, principally albumin.
Calcium is excreted in the urine, faeces and in sweat. Urinary excretion depends on glomerular filtration and tubular resorption.
Vitamin D3 is absorbed in the intestine.
Distribution and biotransformation
Vitamin D3 is transported by protein binding in the blood to the liver (where it undergoes the first hydroxylation to 25-hydroxycholecalciferol) and to the kidneys (second hydroxylation to 1,25-dihydroxycholecalciferol, the active metabolite of vitamin D3).
Non-hydroxylated vitamin D3 is stored in muscle and adipose tissues.
The plasma half-life is in the order of several days; vitamin D3 is eliminated in the faeces and urine.
At doses far higher than the human therapeutic range teratogenicity has been observed in animal studies. No other relevant data is available that has not been mentioned elsewhere in the SmPC (see section 4.6 and 4.9).
