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.
