Warnings and Precautions

If you are on long-term treatment, your doctor may occasionally want to check your blood calcium levels and take urine samples to monitor kidney function. Depending on the results, your doctor may reduce the dose or decide to interrupt treatment.

Taking Ideos Unidia with Other Medications
Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.
Consult your doctor if you are taking any of the following medications:
Calcium salts may decrease the absorption of iron, zinc, and strontium ranelate. Consequently, iron, zinc, or strontium ranelate preparations should be taken at least two hours before or after Ideos Unidia.
Taking Ideos Unidia with Food, Drinks, and Alcohol
This medication may interact with certain foods that contain oxalic acid (e.g., spinach and rhubarb), phosphates (e.g., bran), or phytic acid (e.g., whole grains), as these may reduce the absorption of calcium contained in Ideos Unidia.
Pregnancy, Breastfeeding, and Fertility

Due to the high dose of Vitamin D, this medication is not indicated during pregnancy and breastfeeding. In pregnant women, calcium and vitamin D overdoses should be avoided, as permanent hypercalcemia is related to adverse effects on fetal development.
Ideos Unidia may be used during breastfeeding, but your doctor should be informed. This should be considered when administering additional vitamin D to the child.
