1. What Natecal D3 is and what it is used for
Natecal D3 chewable tablets contain two active substances, calcium carbonate and cholecalciferol (vitamin D3). Both calcium and vitamin D3 are found in the diet and vitamin D is also produced in the skin after exposure to the sun. Natecal D3 chewable tablets are used 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.
2. What you need to know before you take Natecal D3
Before taking this medicine you should first consult with your doctor or pharmacist to check if your vitamin D or calcium levels are too low or at risk of 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)
Warnings and precautions
Talk to your doctor or pharmacist before taking 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).
- If you have sarcoidosis (your doctor will be able to tell you if you do).
- If you are taking these tablets for a long period of time, your doctor may monitor your calcium levels and kidney function via routine testing.

Tell your doctor or pharmacist if you are taking:

- 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.
