1) what calcichew 500mg is and what it is used for
Calcichew 500mg Chewable Tablets are orange flavoured chewable tablets containing the active ingredient calcium. Calcium is found in the diet and is an important substance in bone formation.
Calcichew 500mg is used to treat and prevent calcium deficiency which may occur if 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. It may also be given to patients receiving kidney dialysis to remove the phosphate from the blood that cannot be removed by dialysis.
2) what you need to know before you take calcichew 500mg
Do not take Calcichew 500mg Chewable Tablets if you:
- are allergic (hypersensitive) to calcium or any of the other ingredients of this medicine (listed in section 6)
- have a condition that causes excessive amounts of calcium in your blood or urine (hypercalcaemia or hypercalciuria)
- have kidney stones.
- 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.
Your serum calcium or phosphate levels, or urinary calcium excretion must be monitored if you have any of the following conditions:
- kidney problems
- you are on long-term treatment with Calcichew
- you are already taking additional doses of calcium
If you have increased calcium levels in the blood or develop signs of kidney problems, the dose of Calcichew 500mg should be reduced or the treatment discontinued.
Other medicines and Calcichew 500mg
Tell 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 500mg 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 500mg.
- 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 500mg.
- Bisphosphonates should be taken at least one hour before Calcichew 500mg.
- 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 500mg.
If you are taking any of the above-mentioned medicines, your doctor will give you further instructions.

Additional Information
Calcichew 500mg contains calcium designed to keep bones healthy. Calcium is an essential component of bones.
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.
People with diets and lifestyles that mean they will obtain less than the recommended intake of calcium are at risk of weakened bones. Prolonged lack of adequate calcium 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 500mg have been designed to give people, whose intake of calcium is 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, 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.
If you are concerned about osteoporosis, please contact the National Osteoporosis Society, Camerton, Bath BA2 0PJ. Tel: 01761 471 771, Fax: 01761 471 104 or email:
