1. What is Colecalciferol Alter and what is it used for
Colecalciferol Alter contains the active substance colecalciferol (vitamin D3). Vitamin D3 can be found in some foods and is produced by the body when the skin is exposed to sunlight. Vitamin D helps the body absorb calcium in the kidneys and intestines, which helps form bones. A deficiency of vitamin D is the main cause of rickets (poor bone mineralization in children) and osteomalacia (inadequate bone mineralization in adults).
Colecalciferol is used to prevent and treat vitamin D deficiency in adults.
2. What you need to know before you take Colecalciferol Alter
Do not take Colecalciferol Alter:
- 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 (hypercalcemia) or urine (hypercalciuria);
- if you have kidney stones (renal calculi) or severe kidney failure;
- if you have high levels of vitamin D3 in your blood (hypervitaminosis D)
- if you are allergic to peanuts or soy, as it contains soybean oil.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before taking colecalciferol if you:

- are being treated with certain heart medications (e.g., cardiac glycosides, such as digoxin).
- have sarcoidosis (an autoimmune disease that can cause increased levels of vitamin D in the body).
- are being treated with diuretics (e.g., benzothiadiazine)
- are immobilized
- have pseudohypoparathyroidism
- are being treated with medications that contain vitamin D3, or are taking foods or milk enriched with vitamin D3.
- are likely to be exposed to a lot of sunlight while using colecalciferol
- are taking other calcium supplements. Your doctor should monitor your blood calcium levels to ensure they are not too high during your treatment with colecalciferol.
- have kidney disease or tend to form kidney stones. Your doctor may want to monitor your blood and urine calcium levels.
- your doctor should monitor your blood calcium levels through laboratory tests if your daily intake of vitamin D3 exceeds 1,000 IU for a prolonged period.
Children and adolescents.
The use is not recommended in children and adolescents under 18 years of age.
Other medicines and Colecalciferol Alter
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is especially important if you are taking:
- medicines for heart or kidney disease, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). When these medicines are used at the same time as vitamin D3, they can cause a significant increase in blood and urine calcium levels.
- medicines that contain vitamin D3 or foods rich in vitamin D3, such as some types of milk enriched with vitamin D3.
- actinomycin (a medicine used to treat some types of cancer) and imidazole antifungals (e.g., clotrimazole and ketoconazole, which are medicines used to treat fungal diseases). These medicines can interfere with the processing of vitamin D3 in the body.
- medicines for the treatment of tuberculosis, such as rifampicin and isoniazid
- the following medicines, as they may interfere with the effect or absorption of vitamin D3:
- antiepileptic medicines (anticonvulsants), barbiturates;
- glucocorticoids (steroid hormones such as hydrocortisone or prednisolone), as they may reduce the effect of vitamin D3;
- medicines that lower cholesterol levels in the blood (such as cholestyramine or colestipol);
- certain medicines used to lose weight by reducing fat absorption (e.g., orlistat);
- certain laxatives (such as liquid paraffin).
Taking Colecalciferol Alter with food, drinks, and alcohol
You should take colecalciferol preferably with food to help absorb vitamin D3.
