Patient leaflet - Thorens 25 000 IU capsules hard
1. What THORENS is and what it is used for
THORENS hard capsules contains the active ingredient colecalciferol (vitamin D3). Vitamin D3, can be found in some foods and is also produced by the body when skin is exposed to sunlight. Vitamin D3 helps the kidneys and intestine absorb calcium and it helps build bones. Vitamin D3 deficiency is the predominant cause of rickets (defective mineralization of bones in children) and osteomalacia (inadequate mineralization of bones in adults).
THORENS hard capsules is used for initial treatment of clinically relevant vitamin D deficiency in adults.
2. What you need to know before you use THORENS
Do not use THORENS:
- if you are allergic to vitamin D3 or any of the other ingredients of this medicine (listed in section 6);
- if you have high levels of calcium in your blood (hypercalcaemia) or urine (hypercalciuria);
- if you have kidney stones (renal calculi) or severe renal impairment;
- if you have high levels of vitamin D3 in your blood (hypervitaminosis D)
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using THORENS if you:
- are undergoing treatment with certain medicines used to treat heart disorders (eg, cardiac glycosides, such as digoxin); • have sarcoidosis (an immune system disorder which may cause increased levels of vitamin D3 in the body); • are treated with diuretics (e.g. benzothiadiazine)
- are immobilized
- suffer from pseudohypoparathyroidism • are taking medicines containing vitamin D3, or eating foods or milk enriched with vitamin D3;
- are likely to be exposed to a lot of sunshine whilst using THORENS;
take additional supplements containing calcium. Your doctor will monitor your blood levels of calcium to make sure they are not too high whilst you are using THORENS;
- have kidney damage or disease and if you have a tendency for the formation of renal stones. Your doctor may want to measure the levels of calcium in your blood or urine.
- take a daily dose of vitamin D3 exceeding 1,000 I.U. over a long period of time, your doctor should monitor the level of calcium in your blood by lab test.

Other medicines and THORENS
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. This is especially important if you are taking:
- medicines that act on the heart or kidneys, such as cardiac glycosides (eg, digoxin) or diuretics (eg, bendroflumethiazide). When used at the same time as vitamin D3 these medicines may cause a large increase in the level of calcium in the blood and urine; • medicines containing vitamin D3 or eating food rich in vitamin D3, such as, some types of vitamin D3-enriched milk; • actinomycin (a medicine used to treat some forms of cancer) and imidazole antifungals (eg, clotrimazole and ketoconazole, medicines used to treat fungal disease). These medicines may interfere with the way your body process vitamin D3; • medicines to treat tuberculosis e.g rifampicin, isoniazid;
- the following medicines because they can interfere with the effect or the absorption of vitamin D3:
- antiepileptic medicines (anticonvulsants), barbiturates;
- glucocorticoids (steroid hormones such as hydrocortisone or prednisolone). These can decrease the effect of vitamin D3; - medicines that lower the level of cholesterol in the blood (such as cholestyramine, or colestipol);
- certain medicines for weight loss that reduce the amount of fat your body absorbs (eg, orlistat);
- certain laxatives (such as liquid paraffin).
