1. WHAT ALPHANATE® IS AND WHAT IT IS USED FOR
Alphanate® is supplied as a powder for solution for
injection containing approximately 250, 500, 1000 or
1500 IU of human coagulation factor VIII and 300, 600,
1200 or 1800 IU of human von Willebrand factor per
vial (Note IU stands for international unit, a standard

or 180 IU VWF/ml.
Alphanate® is one of the group of medicines called
Alphanate® is used for the treatment and prevention
of bleeding in patients with haemophilia A (congenital
factor VIII deficiency).
Alphanate® is used for the treatment and prevention
of bleeding (haemorrhage) or surgical bleeding in
von Willebrand disease (VWD), when desmopressin
(DDAVP) treatment alone is ineffective or contraindicated.
This product may be used in the management of
acquired factor VIII deficiency.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using
• Rarely you may have an anaphylactic reaction
(a sudden severe allergic reaction) such as
rash, tightness of the chest, dizziness, vertigo or
nausea, or feeling dizzy when you are standing.
If these symptoms occur, you must stop using the
product immediately and contact your doctor.
• Your doctor should perform some tests to make
sure that the dosage of Alphanate® you are
receiving is enough to achieve and maintain
appropriate factor VIII levels and thus stop any
• If your bleeding is not controlled with Alphanate®,
consult your doctor immediately. You may have
developed factor VIII inhibitors, these are antibodies
which block the clotting effect of factor VIII. Your
doctor will perform some tests to confirm whether
the inhibitors are present in your blood.
• During the treatment of the von Willebrand
disease, there is a chance you may develop blood
clots, particularly if you have known clinical risk
factors. Therefore, your doctor should perform
some tests to detect early signs of blood clots and
recommend the treatment if necessary.
• Patients with von Willebrand disease, especially
type 3 patients, may develop antibodies (inhibitors)
to von Willebrand factor. Your doctor may perform
more blood tests to confirm whether the inhibitors
are present in your blood.
When medicines are made from human blood or
plasma, certain measures are put in place to prevent
infections being passed on to patients. These include:
- careful selection of blood and plasma donors to
make sure those at risk of carrying infections are
- the testing of each donation and pools of plasma
for signs of virus/infections,
- the inclusion of steps in the processing of the
blood or plasma that can inactivate or remove
Despite these measures, when medicines prepared
from human blood or plasma are administered,
the possibility of passing on infection cannot be
totally excluded. This also applies to any unknown or
emerging viruses or other types of infections.
The measures taken are considered effective for
enveloped viruses such as human immunodeficiency
virus (HIV), hepatitis B virus and hepatitis C virus.
The measures taken may be of limited value against
non-enveloped viruses such as hepatitis A virus and
parvovirus B19. Parvovirus B19 infection may be
serious for pregnant women (foetal infection) and for
individuals whose immune system is depressed or who
have some types of anaemia (e.g. sickle cell disease or
Your doctor may recommend that you consider
vaccination against hepatitis A and B if you
regularly/repeatedly receive human plasma-derived
factor VIII products.
It is strongly recommended that every time you receive
a dose of Alphanate® the name and batch number of
the product are recorded in order to maintain a record
of the batches used.
See also section 4.
Other medicines and Alphanate®
Tell your doctor or pharmacist if you are taking, have
recently taken or might take any other medicines.
No interactions of Alphanate® with other medicines
Do not mix Alphanate® with any other medicines that
you receive by injection.
Pregnancy and breast-feeding
Based on the rare occurrence of haemophilia A in
women, experience regarding the use of FVIII/VWF
complex during pregnancy and breast-feeding is not

Driving and using machines
Alphanate® has little or none effect on your ability to
drive and use machines.
The residual content of sodium in Alphanate®, arising
from the manufacturing process, does not exceed
23 mg (1 mmol) per vial. This is equivalent to 1.15%
of the recommended maximum daily intake of sodium
for an adult. However, depending on the body weight of
the patient and the posology, the patient may receive
more than one vial.
3. HOW TO USE ALPHANATE®
Reconstitute the product as described at the end
of this leaflet (please see pictograms on the back
of the leaflet). The product must be given by
intravenous route. The administration rate should
be 3 ml/min and never more than 10 ml/min to
avoid undesirable side effects. Inject Alphanate®
immediately after reconstitution.
The amount of Alphanate® you should use depends
on many factors, such as your weight, your clinical
status and the type and severity of bleeding. Your
doctor will calculate the dose, the frequency and
the intervals of administration of Alphanate® in
order to reach the necessary level of factor VIII or
von Willebrand factor in your blood.
Your doctor will tell you the duration of your
treatment with Alphanate®.
You will be given full training before using
Alphanate® without the hospital supervision.
Please refer to all your training materials or contact
your local haemophilia centre for more information.
You should not self-administer Alphanate® alone:
always have a responsible adult present.
Use in children and adolescents

recommend the use of Alphanate® in children less
than 6 years of age for the authorised indications.

4. POSSIBLE SIDE EFFECTS
Like all medicines, this medicine can cause side
effects, although not everybody gets them.
On rare occasions, you may have some of the
following side effects after the administration
of Alphanate®. Please contact your doctor
immediately if you experience:
• itching, local reactions at the injection site (e.g.
burning and transitory reddening)
• allergic reactions (e.g. tightness of the chest/
feeling unwell, dizziness, nausea and slight
drop of blood pressure than can make you feel
dizzy when you are standing)
• faster heart beat (tachycardia)
Occasionally an anaphylactic shock may occur. If
you observe any of the following symptoms during
the injection/perfusion, interrupt the injection/
perfusion and contact your doctor immediately:
• tightness of the chest/feeling unwell
• slight hypotension (slight drop of blood pressure
with dizziness when you are standing)
Allergic reactions to the components of the product
cannot be totally excluded. The formation of
neutralising antibodies of factor VIII (inhibitors)
is a well-known complication in the treatment of
patients with haemophilia A. Study results show
that first time users of factor VIII are mainly
affected. You will be carefully monitored for the
development of these inhibitors.
There is a chance of blood clots, particularly if you
have known clinical risk factors.
Reporting of side effects
If you get any side effects, talk to your doctor,
pharmacist or nurse. This includes any possible
side effects not listed in this leaflet. You can
