1. What is THORENS and what is it used for

THORENS oral solution contains cholecalciferol (Vitamin D). Vitamin D is found in some foods and is also produced by the body when the skin is exposed to sunlight. Vitamin D helps the body absorb calcium in the kidneys and intestines and supports bone tissue formation. A deficiency of Vitamin D is the main cause of rickets (disrupted bone mineralization in children) and osteomalacia (insufficient bone mineralization in adults). THORENS oral solution is used to treat clinically significant Vitamin D deficiency in adults.

2. Important information before taking THORENS

When not to take the medicine:

• if the patient is allergic to Vitamin D or any other component of this medicine (listed in section 6);
• if the patient has elevated calcium levels in the blood (hypercalcemia) or urine (hypercalciuria);
• if the patient has kidney stones (nephrolithiasis) or severe kidney disorders;
• if the patient has elevated Vitamin D levels in the blood (hypervitaminosis D).

Warnings and precautions

Before starting to take THORENS, the patient should discuss it with their doctor or pharmacist if:

• the patient is taking certain heart medications (e.g., digitalis glycosides, such as digoxin);
• the patient has sarcoidosis (an immune system disorder that can cause elevated Vitamin D levels in the body);
• the patient is taking medications containing Vitamin D or foods enriched with Vitamin D;
• there is a possibility of exposure to large amounts of sunlight during THORENS treatment;
• the patient is taking additional calcium supplements. In this case, the doctor will monitor the patient's blood calcium levels to ensure they are not too high during THORENS treatment;
• the patient has damaged or diseased kidneys. In this case, the doctor may decide to monitor the patient's blood or urine calcium levels;
• the patient has been taking Vitamin D for a long time in a daily dose exceeding 1000 IU (1000 international units). In this case, the doctor should monitor the patient's blood calcium levels through laboratory tests.

Children and adolescents

Using this medicine in children and adolescents under 18 years of age is not recommended.

THORENS and other medicines

The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. This is especially important if the patient is taking:

• medicines that affect the heart or kidneys, such as digitalis glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). These medicines, when taken at the same time as Vitamin D, may cause a significant increase in blood and urine calcium levels;
• medicines containing Vitamin D or foods rich in Vitamin D, such as certain types of Vitamin D-enriched milk;
• actinomycin (a medicine used to treat certain types of cancer) and antifungal medicines that are imidazole derivatives (e.g., clotrimazole and ketoconazole - medicines used to treat fungal infections). These medicines may affect the chemical changes that Vitamin D undergoes in the body;
• the following medicines, as they may affect the effects of Vitamin D or its absorption:
• antiepileptic medicines (anticonvulsants), barbiturates;
• glucocorticoids (steroid hormones, including hydrocortisone and prednisolone). They may reduce the effects of Vitamin D;
• medicines that lower cholesterol levels in the blood (e.g., cholestyramine or colestipol);
• certain weight loss medicines that reduce the amount of fat absorbed from the gastrointestinal tract (e.g., orlistat);
• certain laxatives (e.g., liquid paraffin).
