Natecal D3 chewable tablets contain two active substances, calcium carbonate and cholecalciferol (vitamin D3). Both

Natecal D3 chewable tablets may be prescribed by doctors to treat and prevent vitamin D/calcium deficiency.
Natecal D3 is used:
- In the correction of calcium and vitamin D deficiencies in the elderly,
- In combination with osteoporosis treatments where calcium and vitamin D levels are too low or where there is a high
risk of them being too low.
Do not take Natecal D3
• If you are hypersensitive to calcium, vitamin D3 or to any of the other ingredients of Natecal D3 (in particular soya
bean oil)
• If you have high levels of calcium in your blood (hypercalcaemia) or urine (hypercalciuria)
• If you are suffering from kidney failure;
• If you have kidney stones
• If you have high levels of vitamin D in your blood (hypervitaminosis D)
Take special care with Natecal D3
• If you have had kidney stones or other kidney problems (your doctor will need to monitor your treatment carefully
if your kidneys are not working properly to make sure you do not build up too much calcium in your blood)
• If you stay in bed for a long period (months) and if you have osteoporosis (brittle bones) because you may have
high levels of calcium in your blood
• If you are taking any other medicines containing calcium or vitamin D (your doctor or your pharmacist will be able
to tell you if you do)

Taking other medicines
Do not take the product without talking to your doctor or pharmacist if you are taking:

medicines before taking Natecal D3 chewable tablets

that a period of at least 3 hours has to pass before taking Natecal D3 chewable tablets
• Phenytoin (a medicine for epilepsy) and barbiturates (medicines which are used for epilepsy or which help you
sleep), as they may make the vitamin D3 less effective.
• Orlistat (a medicine used to treat obesity), cholestyramine, laxatives such as paraffin oil, as they may reduce the
amount of vitamin D3 you absorb.

as the amount absorbed may be reduced. They should be taken at least 2 hours before or after Natecal D3.
