1. What is ANNEXXO and what is it used for

The active substance of ANNEXXO is cholecalciferol (vitamin D).
Vitamin D helps the body absorb calcium and supports bone formation and lowers parathyroid hormone (PTH) levels.
This medicine is recommended in the following cases:

  • Prevention or treatment of vitamin D deficiency. Vitamin D deficiency may occur when the diet or lifestyle does not provide enough vitamin D or when the body needs more vitamin D.

ANNEXXO is intended for use in adults.

2. Important information before taking ANNEXXO

When not to take ANNEXXO

  • if you are allergic to vitamin D or any of the other ingredients of this medicine (listed in section 6),
  • if you have high levels of calcium in the blood or urine,
  • if you have kidney stones or kidney calcification,
  • if you have severe kidney disease
  • if you are already taking additional doses of vitamin D (such as multivitamin preparations or dietary supplements containing vitamin D)
  • if you have high levels of vitamin D in the blood or urine (hypervitaminosis D)

Warnings and precautions

Before starting treatment with ANNEXXO, discuss it with your doctor or pharmacist

  • if you have a high tendency to form kidney stones
  • if you have cancer or any other condition that may affect the bones
  • if you have a disorder of parathyroid hormone balance (pseudohypoparathyroidism)

If you have any of the following conditions, your doctor will monitor your calcium or phosphate levels in the blood or calcium levels in the urine:

  • if you are being treated with this medicine for a long time.
  • if you have kidney function disorders,
  • if you have sarcoidosis; and immune system disorders that may affect the liver, lungs, skin, or lymph nodes.

ANNEXXO and other medicines

Tell your doctor about all the medicines you are taking now or have taken recently, as well as any medicines you plan to take, including those available without a prescription.
In particular, inform your doctor if you are taking any of the following medicines:

  • diuretics - calcium levels in the blood will be regularly monitored;
  • corticosteroids ("steroids", such as prednisolone, dexamethasone) - may require increased vitamin D doses;
  • cholestyramine (a cholesterol-lowering medicine) or laxatives (e.g., paraffin oil) - reduce vitamin D absorption;
  • cardiac glycosides (e.g., digoxin) - the patient should be monitored by a doctor and possibly monitored for ECG and calcium levels in the blood;
  • antiepileptic drugs (used to treat epilepsy), sedatives (such as hydantoin, barbiturates), or primidone - reduce the effect of vitamin D;
  • products containing high doses of calcium: increase the risk of high calcium levels in the blood;
  • products containing high doses of phosphorus - increase the risk of high phosphate levels in the blood;
  • products containing magnesium (such as antacids), should not be used during treatment with vitamin D due to the risk of high magnesium levels;
  • certain antibiotics used to treat tuberculosis (rifampicin, isoniazid) may reduce the effectiveness of cholecalciferol;
  • actinomycin (a medicine used to treat certain types of cancer) and antifungal medicines imidazole and ketoconazole (medicines used to treat fungal infections): these medicines may affect how the body processes vitamin D;
  • orlistat (a weight loss aid) - reduces vitamin D absorption.
