1. what calcitriol is and what it is used for

Calcitriol is a vitamin D product.

Calcitriol is used to treat the following:

  • ■ Bone disease in people with kidney problems (renal osteodystrophy).

  • ■ Weakening of the bones in women after the menopause (change of life). This is also known as post-menopausal osteoporosis.

Calcitriol works by making your body absorb more calcium from your diet. This helps to form healthy bones and reduce bone damage.

2. what you need to know before you take calcitriol

Do not take Calcitriol

  • ■ if you are allergic to calcitriol or any of the other ingredients of this medicine (listed in section 6)

  • ■ if you are allergic to any other „vitamin D metabolite“ medicines (used to treat bone disease). These include alfacalcidol and colecalciferol

  • ■ if you have high levels of calcium in your blood (hypercalcaemia)

  • ■ if you have extra deposits of calcium in your body (metastatic calcification)

  • ■ if you are unwell because of high levels of vitamin D in your body.

Do not take Calcitriol if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Calcitriol.

Warnings and precautions

Talk to your doctor or pharmacist before taking Calcitriol

  • ■ if you are finding it difficult to move about (for example, after an operation).

  • ■ if you have kidney problems (the doctor may need to monitor the phosphate levels in your blood and diet).

Other medicines and Calcitriol

Tell your doctor or pharmacist if you are taking/using, have recently taken/used or might take/use any other medicines. This includes medicines that you buy without a prescription and herbal medicines. This is because Calcitriol can affect the way some medicines work. Also some other medicines can affect the way Calcitriol works.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

Other medicines containing vitamin D.

Diuretics, also called ‘water tablets’ (used to treat high blood pressure). These include bendroflumethi­azide, chlortalidone and indapamide.

Medicines like digoxin or digitoxin (used to treat heart disease).

Medicines containing magnesium, such as antacids (used to treat indigestion).

Steroid medicines, such as hydrocortisone, prednisolone and dexamethasone.

Colestyramine, or other ‘ion-exchange resins’ (used to treat high levels of cholesterol in your blood).

Phosphate (the doctor may need to monitor phosphate levels in your blood).

Also tell your doctor or pharmacist if you have taken a medicine containing vitamin D over the last few months that has long-lasting effects. These medicines include ergocalciferol and colecalciferol.

Calcitriol with food and drink

  • ■ DO NOT take any vitamin or food supplements that contain vitamin D while you are taking Calcitriol.

  • ■ DO NOT eat food which has vitamin D added (food which is ‘fortified’ with vitamin D) while you are taking Calcitriol.

  • ■ It is very important to keep to any diet that your doctor has given to you.

  • ■ If you change how much calcium or vitamin D you have in your diet this can increase the risk of side effects (for example, if you eat more dairy products like milk and cheese, or take vitamins without your doctor knowing).

  • ■ Drink plenty of fluids (such as water) as it is important not to become dehydrated. This does not apply if you have kidney problems.
