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.

Osteoporosis patients
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).

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you. If you take the wrong dose, Calcitriol Sandoz may not work as well and your problem may not improve.

How to take it

Swallow the capsules whole with a full glass of water.

Do not open the capsules and do not take any capsules that are damaged.

When to take Calcitriol Sandoz

Take your medicine at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take Calcitriol Sandoz

Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

Calcitriol Sandoz is usually taken continuously for long term treatment. Always tell your doctor if you want to stop taking your medicine as stopping suddenly can lead to a rapid fall in calcium levels.

If you forget to take it

Take your dose as soon as you remember, and continue to take it as you would normally.

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

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.
