Osteofos D3 is a calcium and vitamin D3 supplement for the treatment of certain bone conditions in the elderly. Both calcium and vitamin D are found in the diet and vitamin D is also produced in the skin following exposure to the sun.


What is Osteofos D3

  • A lack of vitamin D and calcium may lead to reduced bone density and bone fractures.
Osteofos D3 may be taken to make up for this deficiency of calcium and vitamin D.

Do not take Osteofos D3 if you:

  •  have an allergy (hypersensitivity) to calcium, colecalciferol or any of the other ingredients of Osteofos D3 (see "Important information about some of the ingredients" section below and Section 6)
  •  are inactive and have high levels of calcium in your blood (hypercalcaemia) or urine (hypercalciuria)
  •  have calcium deposits in the tissues of your body
  •  have serious kidney problems
  •  have kidney stones or calcium stones in general
  •  have abnormally high levels of vitamin D.
  •  are pregnant or breast feeding
  •  if you are less than 12 year of age

Taking other medicines

Please tell your doctor if you are taking or have recently taken any other medicines (including medicines obtained without a prescription), especially: Medicines that decrease the absorption or effect of Osteofos D3:

  •  colestyramine (used to treat high blood cholesterol levels), steroids (such as cortisone), mineral oils (such as paraffin oil used as a laxative or stool softener): these medicines may decrease the absorption of the vitamin D3
  •  phenytoin and barbiturates (e.g. phenobarbital), which are used to treat epilepsy: they may decrease the activity of vitamin D3
  •  some diuretics (water pills e.g. furosemide and ethacrynic acid), antacids (used for indigestion) that contain aluminium salts and thyroid hormones: these medicines can decrease the absorption of calcium and increase its elimination in the stools or urine

Medicines that increase the absorption or effect of Osteofos D3:

  •  some other diuretics (of the thiazide kind, e.g. hydrochlorothiazide) can decrease the elimination of calcium in the urine and thus cause too high calcium levels in the blood
  •  antibiotic drugs, such as penicillin, neomycin and chloramphenicol can increase the absorption of calcium: your doctor may tell you to check your blood calcium during prolonged treatment with Osteofos D3 and any of these drugs

Medicines whose absorption is decreased by Osteofos D3:

  •  tetracycline antibiotics: when taking these leave at least three hours before taking Osteofos D3. Do not take them at the same time
  •  bisphosphonates (medicines used to treat or prevent osteoporosis) and sodium fluoride: when taking these leave at least three hours before taking Osteofos D3

Medicines whose effect is increased by Osteofos D3:

  •  digitoxin (e.g. Lanoxin) or other cardiac glycosides used to treat heart disorders: calcium may increase their effect on the heart

Tell your doctor and ask for his/her advice before taking any other product containing vitamin D or its derivatives while taking Osteofos D3.

Taking Osteofos D3 with food and drink

  • Take Osteofos D3 preferably with your evening meal.
  • Tell your doctor if you usually eat food that contains oxalic acid (e.g. spinach and rhubarb), phosphates (especially from food additives) or phytinic acid (whole cereals), since these may reduce the absorption of calcium contained in Osteofos D3.
  • Tell your doctor and ask for his/her advice before taking foodstuffs which may be fortified with vitamin D.

Pregnancy and breast-feeding

  • Ask your doctor or pharmacist for advice before taking any medicine.
  • Do not use Osteofos D3 if you are pregnant or breastfeeding.
