What it is and what it is used for

FOR

Calcichew-D3 Forte Chewable Tablets are lemon flavoured chewable tablets containing calcium and vitamin D3 which are both important substances in bone formation. Both are found in the diet and vitamin D is also produced in the skin after exposure to the sun. Calcichew-D3 Forte is used to treat and prevent vitamin D/calcium deficiency, which may occur when your diet or lifestyle does not provide enough, or when body requirements are increased. This medicine may also be prescribed or recommended for certain bone conditions, for example osteoporosis, or during pregnancy. 2.

What you need to know before you take it

E CALCICHEW- D3 FORTE Do not take Calcichew- D3 Forte if you:

  • are allergic to calcium, vitamin D, or any of the other ingredients of this medicine (listed in section 6)
  • have severe kidney problems
  • have a condition that causes excessive amounts of calcium in your blood or urine (hypercalcaemia or hypercalciuria) e.g. o renal (kidney) failure o cancer that has affected your bones
  • have excessive amounts of vitamin D in your blood
  • have kidney stones. Warnings and precautions Talk to your doctor or pharmacist before taking Calcichew- D3 Forte:

• • • • •

if you have osteoporosis (brittle bones) and are also unable to move around if you are on long term treatment, especially if you are taking medicines for a heart disorder (cardiac glycosides), or diuretics (used in the treatment of high blood pressure or oedema) if you have signs of impaired kidney function or a high tendency to kidney stone (calculus) formation if you have cancer or any other conditions that may have affected your bones if you have sarcoidosis (an immune system disorder which may cause increased levels of vitamin D in the body).

If you have any of the following conditions your serum calcium or phosphate levels, or urinary calcium excretion must be monitored. Calcichew should be taken under close medical supervision.

  • sarcoidosis (an immune system disorder which may affect your liver, lungs, skin or lymph nodes)
  • kidney problems
  • you are on long-term treatment with Calcichew
  • you are already taking additional doses of calcium or vitamin D. If you have increased calcium levels in the blood or develop signs of kidney problems, the dose of Calcichew-D3 Forte should be reduced or the treatment discontinued. Other medicines and Calcichew- D3 Forte Tell your pharmacist if you are taking, have recently taken or might take any other medicines. In particular, the following medicines may interact with Calcichew-D3 Forte chewable tablets: • thiazide diuretics (water tablets); your serum calcium levels should be monitored regularly. • cardiac glycosides (heart medicines); you should be monitored by electrocardiogram (ECG) and your serum calcium levels measured. • tetracycline antibiotics; these should be taken at least two hours before, or four to six hours afterwards. Calcium carbonate may interfere with the absorption of tetracycline preparations if taken at the same time. • levothyroxine (hormone used to treat thyroid deficiency); these should be taken at least four hours before or after taking Calcichew- D3 Forte • quinolone antibiotics (ciprofloxacin, lomefloxacin, norfloxacin, sparfloxacin): the effect of these medicines may be reduced if taken at the same time as calcium. Take quinolone antibiotics two hours before or six hours after taking CalcichewD3 Forte. • bisphosphonates; should be taken at least one hour before Calcichew-D3 Forte • Calcium salts may decrease the absorption of iron, zinc and strontium ranelate. Consequently iron, zinc or strontium ranelate preparations should be taken at least two hours before or after Calcichew-D3 Forte • Orlistat (used to treat obesity) may disturb the absorption of fat-soluble vitamins, e.g. vitamin D3. If you are taking any of the above-mentioned medicines, your pharmacist will give you further instructions. Taking Calcichew-D3 Forte with food and drink Calcichew-D3 Forte can be taken with or without food and drink.

Pregnancy and breast-feeding If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your pharmacist for advice before taking Calcichew-D3 Forte. If you are pregnant, you may use Calcichew-D3 Forte in case of a calcium and vitamin D deficiency. During pregnancy you should not take more than 2500 mg calcium and 4000 IU vitamin D per day, as overdoses may harm the unborn child. Calcichew-D3 Forte can be used during breast-feeding. Calcium and vitamin D3 pass into breast milk. This should be considered when giving additional vitamin D to the child. Driving and using machines Calcichew- D3 Forte has no known influence on the ability to drive or use machines. Calcichew- D3 Forte contains isomalt and sucrose. Calcichew-D3 Forte contains isomalt (E953) and sucrose (E420): if you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

This leaflet was last revised in June 2024. Additional Information Calcichew-D3 Forte are a combination of calcium and vitamin D designed to keep bones healthy. Calcium is an essential component of bones while vitamin D plays an important role in the absorption of calcium from food. Requirements for calcium increase with age and, although many people obtain enough calcium from their diet, some people may require a supplement in order that their body has all the calcium it needs to maintain healthy bones. Vitamin D is produced largely from the action of sunlight. Certain foodstuffs do contain vitamin D in reasonable amounts but it is not always possible to obtain all the vitamin D you need from your diet. People who do not get out and about, for instance those who are housebound or people living in nursing and residential homes, may not receive all the vitamin D they need. People with diets and lifestyles that mean they will obtain less than the recommended intake of calcium and vitamin D are at risk of weakened bones. Prolonged lack of adequate calcium and vitamin D intake can lead to the development of osteoporosis, a condition where bones become weak to a level that minimal trauma (for example, a fall) can result in a fracture, most typically at the hip, spine or wrist. Calcichew-D3 Forte have been designed to give people whose intakes of calcium and vitamin D are low a boost to the recommended amounts. Maintaining healthy bones and helping to avoid osteoporosis is an important issue for many people. There are many ways that people can help themselves: regular exercise, a balanced diet with an adequate intake of calcium and vitamin D and, for some people, advice on how to prevent falls which may lead to fracture. The Royal Osteoporosis Society is a national charity dedicated to improving the diagnosis, prevention and treatment of osteoporosis. The Royal Osteoporosis Society offers support to people with osteoporosis and raises awareness of the importance of healthy bones.

4.1. Therapeutic indications

The treatment and prevention of vitamin D/calcium deficiency (characterised by raised serum alkaline phosphatase levels associated with increased bone loss, raised levels of serum PTH and lowered 25-hydroxyvitamin D) particularly in the housebound and institutionalised elderly subjects.

The supplementation of vitamin D and calcium as an adjunct to specific therapy for osteoporosis, in pregnancy, in established vitamin D dependent osteomalacia, and in other situations requiring therapeutic supplementation of malnutrition.

4.2. Posology and method of administration

Posology

Adults and elderly:

Adjunctive therapy in osteoporosis and Calcium and vitamin D deficiency

One tablet twice daily.

Special Patient Populations

Paediatric population:

Calcichew-D3 Forte Chewable Tablets are not intended for use in children.

Impaired hepatic function

No dose adjustment is required.

Impaired renal function

Calcichew-D3 Forte Chewable Tablets should not be used in patients with severe renal impairment (see section 4.3).

Method of Administration

Oral. The tablets should be chewed or sucked.

4.3. Contraindications

• Hypersensitivity to the active substances or to any of the excipients listed in section 6.1

• Diseases and/or conditions resulting in hypercalcaemia and/or hypercalciuria

• Severe renal impairment (glomerular filtration rate < 30 ml/min)

• Renal calculi (nephrolithiasis)

• Hypervitaminosis D

4.4. Special warnings and precautions for use

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 patients on concomitant treatment with cardiac glycosides or 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 the dose should be reduced or the treatment discontinued.

Calcichew-D3 Forte Chewable Tablets should be used with caution in patients with hypercalcaemia or signs of impaired 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 colecalciferol is not metabolised normally and other forms of vitamin D should be used (see section 4.3, contraindications).

During concomitant treatment with other high dose sources of vitamin D and/or medications or nutrients (such as milk) containing calcium, there is a risk of hypercalcaemia and milk-alkali syndrome with subsequent kidney function impairment. In these patients serum calcium levels should be followed and renal function should be monitored.

Calcichew-D3 Forte Chewable Tablets should be prescribed with caution to patients suffering from sarcoidosis because of the risk of increased metabolism of vitamin D3 to its active form. These patients should be monitored with regard to the calcium content in serum and urine.

Calcichew-D3 Forte Chewable Tablets should be used with caution in immobilised patients with osteoporosis due to the increased risk of hypercalcaemia.

Calcichew-D3 Forte Chewable Tablets contain isomalt (E953) and sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

4.5. Interaction with other medicinal products and other forms of interaction

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.

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 carbonate.

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.

The efficacy of levothyroxine can be reduced by the concurrent use of calcium, due to decreased levothyroxine absorption. Administration of calcium and levothyroxine should be separated by at least four hours.

The absorption of quinolone antibiotics may be impaired if administered concomitantly with calcium. Quinolone antibiotics should be taken two hours before or six hours after intake of calcium.

If a bisphosphonate is used concomitantly, this preparation should be administered at least one hour before the intake of Calcichew-D3 Forte Chewable Tablets since gastrointestinal absorption may be reduced.

Calcium salts may decrease the absorption of iron, zinc and strontium ranelate. Consequently, iron, zinc or strontium ranelate preparations should be taken at least two hours before or after Calcichew-D3 Forte Chewable Tablets.

Treatment with orlistat may potentially impair the absorption of fat-soluble vitamins (e.g. vitamin D3).

4.6. Fertility, pregnancy and lactation

Pregnancy

Calcichew-D3 Forte Chewable Tablets can be used during pregnancy, in case of a calcium and vitamin D deficiency. During pregnancy the daily intake should not exceed 2500 mg calcium and 4000 IU vitamin D. Studies in animals have shown reproductive toxicity with high doses of vitamin D (see section 5.3). In pregnant women, overdoses of calcium and vitamin D should be avoided as permanent hypercalcaemia has been related to adverse effects on the developing foetus. There are no indications that vitamin D at therapeutic doses is teratogenic in humans.

Lactation

Calcichew-D3 Forte Chewable Tablets can be used during breast-feeding. Calcium and vitamin D3 pass into breast milk. This should be considered when giving additional vitamin D to the child.

4.7. Effects on ability to drive and use machines

Calcichew-D3 Forte Chewable Tablets have no known influence on the ability to drive and use machines.

4.8. Undesirable effects

Adverse reactions are listed below, by system organ class and frequency. Frequencies are defined as: uncommon (≥1/1,000, to <1/100); rare (≥1/10,000, to <1/1,000), very rare (≤1/10,000) or not known (cannot be estimated from the available data).

Immune system disorders

Not known: Hypersensitivity reactions such as angio-oedema or laryngeal oedema.

Metabolism and nutrition disorders

Uncommon: Hypercalcaemia and hypercalciuria.

Very rare: Milk-alkali syndrome (frequent urge to urinate; continuing headache; continuing loss of appetite; nausea or vomiting; unusual tiredness or weakness; hypercalcaemia, alkalosis and renal impairment). Seen usually only in overdose (see section 4.9).

Gastrointestinal disorders

Rare: Constipation, dyspepsia, flatulence, nausea, abdominal pain and diarrhoea.

Skin and subcutaneous disorders

Rare: Pruritus, rash and urticaria.

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 at: www.mhra.gov.uk/yellowcard.

4.9. Overdose

Symptoms

Overdose can lead to hypercalcaemia and hypervitaminosis D. Symptoms of hypercalcaemia may include anorexia, thirst, nausea, vomiting, constipation, abdominal pain, muscle weakness, fatigue, mental disturbances, polydipsia, polyuria, bone pain, nephrocalcinosis, nephrolithiasis and in severe cases, cardiac arrhythmias. Extreme hypercalcaemia may result in coma and death. Persistently high calcium levels may lead to irreversible renal damage and soft tissue calcification.

Milk-alkali syndrome may occur in patients who ingest large amounts of calcium and absorbable alkali.

Treatment of hypercalcaemia

Treatment is essentially symptomatic and supportive. The treatment with calcium must be discontinued. Treatment with thiazide diuretics and cardiac glycosides must also be discontinued (see section 4.5). Treatment: rehydration, and, according to severity of hypercalcaemia, isolated or combined treatment with loop diuretics, bisphosphonates, calcitonin and corticosteroids should be considered. Serum electrolytes, renal function and diuresis must be monitored. In severe cases, ECG and CVP should be followed.
