HOW TO TAKE CALCITRIOL SANDOZ
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how many capsules to take each day. This will vary depending on the nature of your illness, the level of calcium in your blood and your individual response to this medicine.
Your doctor will need to take regular measurements of the calcium level in your blood while you are taking this medicine.
Generally the daily dose for adults is 0.25 micrograms (one capsule) taken twice daily.
Osteodystrophy, hypoparathyroidism and rickets
Generally the initial daily dose for adults is 0.25 micrograms (one capsule) given in the morning. If calcium levels have not improved significantly after 2 to 4 weeks treatment, your doctor may gradually increase the dose in 0.25 microgram steps until a satisfactory calcium level in your blood is achieved.
For infants and small children with hypoparathyroidism
As for adults, the correct dose of this medicine must be determined by your doctor. For children between 1 and 5 years of age the recommended daily dose is 0.25 to 0.75 micrograms (one to three capsules).

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
