WHAT COLECALCIFEROL INTERNIS IS AND WHAT IT IS
Colecalciferol Internis are soft capsules. They contain the active ingredient:
Vitamin D3 (800 IU colecalciferol equivalent to 20 micrograms Vitamin D3)
Vitamin D is found in the diet and is also produced in the skin after exposure to the
sun. Often vitamin D is given in combination with calcium. Colecalciferol Internis is
recommended for use when you have a normal intake of dietary calcium.
Colecalciferol Internis may be prescribed by your doctor to treat or prevent vitamin D
deficiency. Deficiency of vitamin D may occur when your diet or lifestyle does not
provide you enough vitamin D or when your body requires more vitamin D (for
instance when you are pregnant). Colecalciferol Internis may also be prescribed for
certain bone conditions, such as thinning of the bone (osteoporosis) when it will be
given to you with other medicines.
BEFORE YOU TAKE COLECALCIFEROL INTERNIS
Do not take Colecalciferol Internis if you
are allergic (hypersensitive) to vitamin D or any of the other ingredients in the
capsules (these are listed in section 6, Further information).
Have high levels of vitamin D in your blood (hypervitaminosis D)
Have high blood levels of calcium (hypercalcaemia) or high urine levels of
Have kidney stones or serious kidney problems
Check with your doctor before taking Colecalciferol Internis if
You have kidney damage or disease. Your doctor may want to measure the
levels of calcium in your blood or urine.
You are being treated for heart disease.
You have sarcoidosis (an immune system disorder which may affect your
liver, lungs, skin or lymph nodes).
You are already taking additional doses of calcium or vitamin D. Whilst you
are taking Colecalciferol Internis your doctor will monitor your blood levels of
calcium to make sure they are not too high.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other
medicines, including medicines obtained without a prescription.
In particular the following medicines may interact with Colecalciferol Internis:
Heart medicines (cardiac glycosides such as digoxin). Your doctor may
monitor your heart with an electrocardiogram (ECG) and measure the levels of
calcium in your blood.
Medicines to treat epilepsy (such as phenytoin) or medicines to make you
sleep (barbiturates such as phenobarbitone) as these medicines can decrease
the effect of vitamin D.
Glucocorticoids (steroid hormones such as hydrocortisone or prednisolone).
These can decrease the effect of vitamin D.
Laxatives (such as paraffin oil) or a cholesterol lowering drug called
colestyramine may reduce the absorption of vitamin D.
Actinomycin (a medicine used to treat some forms of cancer) and imidazole
antifungals (medicines such as clotrimazole and ketoconazole used to treat
fungal diseases) as they may interfere with the metabolism of vitamin D.
