1. What is Devik and what is it used for

Devik oral solution contains colecalciferol (vitamin D3). Vitamin D3 can be found in certain foods, as well as being produced by the skin in the presence of sunlight. Vitamin D3 helps the kidneys and intestine absorb calcium and contributes to bone development. A deficiency of vitamin D3 is the main cause of rickets (a mineralization defect of bones in children) and osteomalacia (a mineralization defect of bones in adults).

Devik oral solution is used for the initial treatment of vitamin D deficiency in adults.

Your doctor may prescribe this medicine as a supplement to specific bone loss medication. If you have any further questions, consult your doctor or pharmacist, and always follow their instructions.

2. What you need to know before you take Devik

Do not take Devik

  • If you are allergic to colecalciferol or any of the other ingredients of this medicine (listed in section 6).
  • If you have high levels of calcium in the blood (hypercalcemia) or in the urine (hypercalciuria).
  • If you have kidney stones (renal calculi) or severe kidney failure.
  • If you have high levels of vitamin D3 in the blood (hypervitaminosis D).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before taking Devik:

  • If you are taking certain medicines used to treat heart disorders (e.g., cardiac glycosides, such as digoxin).
  • If you have sarcoidosis (an immune system disorder that can cause an increase in vitamin D levels in the body).
  • If you are taking other medicines that contain vitamin D, or if you take foods or milk enriched with vitamin D.
  • If you are likely to have high sun exposure while taking Devik.
  • If you take additional calcium supplements. Your doctor will monitor your blood calcium levels to ensure they are not too high while taking Devik.
  • If you have kidney problems or any kidney disease. Your doctor may want to measure your blood or urine calcium levels.
  • Your doctor should monitor your blood calcium level with laboratory tests if you take a daily dose of vitamin D3 greater than 1,000 UI for a prolonged period.
  • If you have a parathyroid hormone imbalance (pseudohypoparathyroidism).

Children and adolescents

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

Using Devik with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. It is especially important if you are taking:

  • Medicines that act on the heart or kidneys, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). When taken at the same time as vitamin D, these medicines can cause a significant increase in blood and urine calcium levels.
  • Medicines that contain vitamin D or foods rich in vitamin D, such as some types of vitamin D-enriched milk.
  • Actinomycin (a medicine used to treat some forms of cancer) and imidazole antifungals (e.g., clotrimazole and ketoconazole, medicines used to treat fungal diseases). These medicines can affect how your body processes vitamin D.
  • Medicines for treating tuberculosis, such as rifampicin and isoniazid.
  • The following medicines, as they may interfere with the effect or absorption of vitamin D:
  • Antiepileptic medicines (anticonvulsants), barbiturics.
  • Glucocorticoids (steroid hormones such as hydrocortisone or prednisolone). These medicines can reduce the effect of vitamin D.
  • Medicines that lower blood cholesterol levels (such as cholestyramine or colestipol).
  • Certain weight loss medicines that reduce the amount of fat absorbed by the body (e.g., orlistat).
  • Certain laxatives (such as liquid paraffin).
