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 reduces the level of
parathyroid hormone (PTH).
This medicine is recommended in the following cases:

  • Prevention of vitamin D deficiency in adults with identified risk, when adherence to therapeutic recommendations is not achieved through daily administration of small doses of cholecalciferol or treatment of vitamin D deficiency. Vitamin D deficiency may occur when the diet or lifestyle does not provide sufficient 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 your blood or urine,
  • if you have kidney stones or calcification in the kidneys,
  • 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 your blood or urine (hypervitaminosis D)

Warnings and precautions

Before starting treatment with ANNEXXO, you should 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

ANNEXXO and other medicines

Tell your doctor about all the medicines you are taking now or have recently taken, 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 your blood will be regularly monitored;
  • corticosteroids ("steroids", such as prednisolone, dexamethasone) - it may be necessary to increase the dose of vitamin D;
  • cholestyramine (a cholesterol-lowering medicine) or laxatives (such as paraffin oil) - they reduce the absorption of vitamin D;
  • heart medicines (digitalis glycosides) - you should be monitored by your doctor and your ECG and calcium levels in your blood may be monitored;
  • antiepileptic medicines (used to treat epilepsy), sedatives (such as hydantoin, barbiturates), or primidone - they reduce the effect of vitamin D;
  • products containing high doses of calcium: they increase the risk of high calcium levels in your blood;
  • products containing high doses of phosphorus - they increase the risk of high phosphate levels in your 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 diseases): these medicines may affect how your body processes vitamin D;
  • orlistat (a weight loss aid) - reduces the absorption of vitamin D.
