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.

  • 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.
    • renal (kidney failure)
    • 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 condtions 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

Please inform your doctor or 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 Calcichew-D3 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 doctor will give you further instructions.

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 National Osteoporosis Society (NOS) is a national charity dedicated to improving the diagnosis, prevention and treatment of osteoporosis. The NOS offers support to people with osteoporosis and raises awareness of the importance of healthy bones.
