Read the entire leaflet carefully before starting to take this medication because it contains important information for you

  • Keep this leaflet, as you may need to read it again.
  • If you have any questions, consult your doctor, pharmacist, or nurse.
  • This medication has been prescribed to you only, and you should not give it to others, even if they have the same symptoms as you, as it may harm them.

1. What is Deltius and what is it used for

Deltius oral solution contains colecalciferol (vitamin D3) as the active ingredient. Vitamin D3 can be found in some foods and is produced by our body when the skin is exposed to sunlight. Vitamin D promotes calcium absorption in the kidneys and intestines, helping to form bone. Vitamin D deficiency is the main cause of rickets (mineralization deficiency of bones in children) and osteomalacia (inadequate mineralization of bones in adults).

Deltius oral solution is used for the initial treatment of clinically relevant vitamin D deficiency in adults.

2. What you need to know before taking Deltius

Do not take Deltius

  • if you are allergic to vitamin D3 or any other component of this medication (listed in section 6).
  • if you have high levels of calcium in the blood (hypercalcemia) or urine (hypercalciuria).
  • if you have kidney stones (renal calculi) or severe renal insufficiency.
  • if you have high levels of vitamin D in the blood (hypervitaminosis D).

Warnings and precautions

Consult your doctor or pharmacist before starting to take Deltius if:

  • you are being treated with certain medications for heart conditions (e.g., cardiac glycosides, such as digoxin).
  • you have sarcoidosis (an autoimmune disease that can cause increased levels of vitamin D in the body).
  • you are being treated with medications that contain vitamin D or taking foods or milk enriched with vitamin D.
  • you are likely to be exposed to the sun while using this medication.
  • you are also taking calcium supplements. Your doctor should monitor your calcium levels to ensure they are not too high during your treatment with Deltius.
  • you have kidney disease. Your doctor should 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

Deltius is not recommended for use in children and adolescents under 18 years of age.

Other medications and Deltius

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

  • medications for heart or kidney conditions, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). 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.
  • medications that contain vitamin D or foods rich in vitamin D, such as some types of vitamin D-enriched milk.
  • actinomycin (a medication used to treat certain types of cancer) and imidazole antifungals (e.g., clotrimazole and ketoconazole, medications used to treat fungal diseases). These medications can interfere with how your body processes vitamin D3.
  • the following medications, as they may interfere with the effect or absorption of vitamin D3:
  • antiepileptic medications (anticonvulsants), barbiturics.
  • glucocorticoids (steroid hormones such as hydrocortisone or prednisolone), as they may reduce the effect of vitamin D3.
  • medications that lower cholesterol levels in the blood (such as cholestyramine or colestipol).
  • certain medications used to lose weight by reducing fat absorption (e.g., orlistat);
  • certain laxatives (such as liquid paraffin).

Taking Deltius with food, drinks, and alcohol
