alfacalcidol

One-Alpha contains the active substance alfacalcidol.
One-Alpha belongs to a group of medicines called vitamin D
analogues. It is a type of vitamin D.
Vitamin D controls the levels of two substances in your body.
These substances are called calcium and phosphate. Your
body needs both of these substances for healthy bones and
teeth.
One-Alpha works by increasing the amount of vitamin D in
your body. This means the levels of calcium and phosphate in
your body will increase too.
One-Alpha is used to treat diseases where the amount of
calcium in your body needs changing. It is used to treat:
•Changes in bone caused by kidney failure (osteodystrophy).
•Changes to your parathyroid glands. These are small glands
found in your neck. They make a substance called the
parathyroid hormone. This changes the amount of calcium
in your body.
° The glands may make the amount of calcium in your blood
too high (hyperparathyroidism).
° The glands may make the amount of calcium in your blood
too low (hypoparathyroidism).
•Low levels of calcium in the blood of newborn babies
(hypocalcaemia).
•Softening and deformity of the bones due to lack of calcium
(rickets or osteomalacia).

2. What you need to know before you take One-Alpha

Do not take One-Alpha
•If you are allergic (hypersensitive) to alfacalcidol or any of
the other ingredients. You can find a list of these ingredients
in section 6 of this leaflet.
•If you know you have a condition called hypercalcaemia.
This means you have high levels of calcium in your blood.
•If you know that you have a condition called calcification.
This means you have high levels of calcium in your body
tissues.
If you are unsure if any of the above apply to you, talk to your
doctor before taking One-Alpha.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before taking
One-Alpha
•If you are taking any of the medicines in the ‘Taking other
medicines” section below.

You may get too much calcium or phosphate in your blood
when you take this medicine. Please read section 4 of this
leaflet so you can spot any signs this may be happening to
you. Your doctor may need to change your dose.
While you are taking One-Alpha your doctor will take regular
blood tests. This is very important in children, patients with
kidney problems, or patients on a high dose of medicine. This
is to check the level of calcium and phosphate in your blood
while you take your medicine.
•Your doctor may prescribe another medicine called a
phosphate binding agent to take as well as One-Alpha. This
will help to keep the right amount of phosphate in your
blood.

You must tell your doctor or pharmacist if you are taking any
of the following medicines:
•Anticonvulsants (for example, barbiturates, phenytoin,
carbamazepine or primidone): for epilepsy or fits. You may
need a larger dose of One-Alpha.
•Cardiac glycosides, such as digoxin: for heart problems. You
may get too much calcium in your blood. This may cause an
abnormal heart beat.
•Thiazide diuretics, often called “water pills”: for increasing
the amount of water (urine) that your body makes. You may
get too much calcium in your blood.
•Calcium-containing medicines. You may get too much
calcium in your blood.
•Other medicines that contain vitamin D. You may get too
much calcium in your blood.
•Antacids containing magnesium: for heartburn or
indigestion. You may get too much magnesium in your blood.
• Medicines containing aluminium. Too much aluminium is toxic.
• Bile acid sequestrants such as cholestyramine: for lowering
your cholesterol level, or to help stop some types of diarrhoea
or itching. Your One-Alpha may not enter your blood as usual.

pregnant or are planning to have a baby, ask your doctor or
pharmacist for advice before taking this medicine.

How much One-Alpha to take
Your doctor will tell you how many capsules to take, or to give
your child.
At first you will have weekly blood tests to check the levels of
some substances in your blood. These tests are to check the
levels of calcium, an enzyme called alkaline phosphatase or
the parathyroid hormone. This is so your doctor knows that
you are taking the dose that is right for you. When you are
getting the correct dose you will not need blood tests so often.
