Contents of the package and additional information

Thorens contains the active principle colecalciferol (vitamin D3). Vitamin D3can be found in some foods and is produced by the body when the skin is exposed to sunlight. Vitamin D promotes the absorption of calcium in the kidneys and intestines, aiding in bone formation.

-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 D in your blood (hypervitaminosis D).

Other medications and Thorens

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication. This is especially important if you are taking:

-medications for heart or kidney disease, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumetazide). When these medications are used at the same time as vitamin D3, they can cause a significant increase in calcium levels in the blood and urine.

-actinomycin (a medication used to treat certain types of cancer) and imidazole antifungals (e.g., clotrimazole and ketoconazole, which are medications used to treat fungal diseases). These medications can interfere with the processing of vitamin D3in the body.

-medications for tuberculosis, such as rifampicin and isoniazid

-the following medications, as they may interfere with the effect or absorption of vitamin D3:

• antiepileptic medications (anticonvulsants), barbiturates;
• glucocorticoids (steroid hormones such as hydrocortisone or prednisolone), as they may reduce the effect of vitamin D3.;
