Further information

1. What One-Alpha is and what it is used for
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).

Final draft mock up
2. 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 know that you have any sugar intolerance. You may
have inherited this condition from someone else in your
family.
If you are unsure if any of the above apply to you, talk to your
doctor before taking One-Alpha.


Take special care with One-Alpha

Before you take One-Alpha tell your doctor:

If you are taking another type of medicine called a cardiac
glycoside, such as digoxin. These medicines are used to
treat problems with your heart.

If you have any problems with your kidneys. This includes if
you have kidney stones.
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.

Taking other medicines

Please tell your doctor or pharmacist if you are taking, or have
recently taken any other medicines. This includes any medicines
which you have bought without a prescription.
You must tell your doctor or pharmacist if you are taking any of
the following medicines:

Anticonvulsants: for epilepsy or fits. You may need a larger
dose of One-Alpha.

Barbiturates: for sleeping disorders. 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.

Colestyramine: 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.

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.

Important information about some of the
ingredients of One-Alpha

One-Alpha contains:

Ethanol. This is an alcohol. This medicine contains a very
small amount of ethanol.

Methylparahydroxybenzoate. This is a preservative. It may
give you an allergic reaction. This may happen at any time
after you take your medicine. Please read section 4 of this
leaflet so you can spot any signs this may be happening to
you.

Polyoxyl 40 hydrogenated castor oil. This is used to make
your medicine. It may give you an upset stomach or
diarrhoea.

Sorbitol. This is a type of sugar. If you cannot tolerate any
sugar (sometimes called sugar intolerance) contact your
doctor before you take this medicine. Your medicine contains
22.6 milligrams of sorbitol in one drop.
Please ask your doctor if you are worried about any of the
ingredients in this medicine.

3. How to take One-Alpha
Always use One-Alpha exactly as your doctor has told you. You
should check with your doctor or pharmacist if you are not sure.

How to measure a drop

Do not shake the bottle. Unscrew the bottle cap. You will see a
dropper in the top of the bottle. It is ready to use. Hold the bottle
upside down. A drop will form at the end of the dropper. Let the
drop fall directly into your mouth. You can catch the drop on a
spoon if this is easier.
If the drops do not come out of the bottle straight away, tap the
bottle gently until a drop forms.

How much One-Alpha to take

Your doctor will tell you how many drops to take, or to give your
child. One-Alpha is only to be taken by mouth.
Be careful not to take more drops than you should. You must
check with your doctor or pharmacist if you are not sure how to
take this medicine correctly. This medicine is very strong
(concentrated).

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.

If you forget to take One-Alpha

If you have any further questions about taking this medicine,
please ask your doctor or pharmacist.

Do not use the drops after the expiry date on the carton and
bottle. The expiry date is the last day of that month.

You may also have other tests such as X-rays. This is also so your
doctor knows that the dose is right for you.

4. Possible side effects

Store in a refrigerator (2-8°C). After opening, you should discard
the drops after 28 days. Write the date you first opened the bottle
in the space provided on the carton.

Your doctor may adjust your dose. Your doctor may ask you to
take more or less drops depending on your test results.
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 will
tell you not to take any more medicine. You will need to have
some blood tests. When the blood tests are normal you can start
your medicine again. It is important that you only take half the
dose you had before.

Adults:

The usual starting dose is 10 drops each day. People usually take
between 10 and 30 drops each day. Most people take between 3
and 10 drops each day once the blood test results show the
medicine is working. If you have very low levels of calcium in your
blood, the doctor may prescribe between 30 to 50 drops each day.
Your doctor may prescribe another medicine called a calcium
supplement to take as well as One-Alpha. This will help to keep
the right amount of calcium in your blood.

Elderly:

The usual starting dose is 5 drops each day.

Children:

The dose depends on the weight of the child (called bodyweight).

Newborn and premature babies:
The usual starting dose is 1 to 2 drops per 2 kilograms of
bodyweight each day.
If the level of calcium in their blood is very low, up to 40
drops per 2 kilograms of bodyweight may be needed each
day.
A dose of 2 drops per 2 kilograms bodyweight each day is
used to stop low blood calcium levels in premature babies.




Children weighing less than 20 kilograms:
The usual starting dose is 1 drop per 2 kilograms
bodyweight each day.
Children weighing more than 20 kilograms:
The usual starting dose is 10 drops each day.

If you take more One-Alpha than you should

Tell your doctor straight away. You may need to stop taking this
medicine.
You may get too much calcium or phosphate in your blood. Please
read section 4 of this leaflet so you can spot any signs this may be
happening to you.

If you forget to take your medicine take it as soon as you
remember. Then take the next dose at the usual time.

everybody gets them.
