invitaD3 is a vitamin product containing colecalciferol (equivalent to vitamin D3). Vitamin D can be
found in some foods and also produced by the body when skin is exposed to sunlight. Vitamin D
helps the kidneys and intestine absorb calcium and it helps build bones.

• for the prevention of vitamin D deficiency when there is a significant risk of deficiency or an
increased demand for vitamin D
• with other medicines to treat certain bone conditions, such as thinning of the bone
• to treat vitamin D deficiency that has been confirmed by laboratory tests.

Do not use invitaD3
• if you are allergic to vitamin D or any of the other ingredients of invitaD3 (listed in section 6)
• if you have hypercalcaemia (high levels of calcium in the blood)
• if you have hypercalciuria (high levels of calcium in the urine)
• if you have pseudohypoparathyroidism (disturbed parathyroid hormone metabolism)
• if you have renal calculi (kidney stones)
• if you have hypervitaminosis D (high levels of vitamin D in the blood).
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using invitaD3 if you:
• are undergoing treatment with certain medicines used to treat heart disorders (e.g. cardiac
glycosides, such as digoxin)
• have sarcoidosis (an immune system disorder which may cause increased levels of vitamin D
in the body)
• are taking medicines containing vitamin D, or eating foods or milk enriched with vitamin D
• are likely to be exposed to a lot of sunshine whilst using invitaD3
• take additional supplements containing calcium. Your doctor will monitor your blood levels of
calcium to make sure they are not too high whilst you are using invitaD3

your blood or urine.

Other medicines and invitaD3
Tell your doctor or pharmacist if you are using, have recently used or might use any other
medicines. This is especially important if you are taking:
• medicines that act on the heart or kidneys, such as cardiac glycosides (e.g. digoxin) or
diuretics (e.g. bendroflumethazide). When used at the same time as vitamin D these medicines
may cause a large increase in the level of calcium in the blood and urine
• medicines containing vitamin D or eating food rich in vitamin D, such as, some types of
vitamin D-enriched milk
• actinomycin (a medicine used to treat some forms of cancer) and imidazole antifungals (e.g.
clotrimazole and ketoconazole, medicines used to treat fungal disease). These medicines may
interfere with the way your body process vitamin D
• the following medicines because they can interfere with the effect or the absorption of
vitamin D:
– antiepileptic medicines (anticonvulsants), barbiturates
– glucocorticoids (steroid hormones such as hydrocortisone or prednisolone). These can
decrease the effect of vitamin D
– medicines that lower the level of cholesterol in the blood (such as cholestyramine, or
