18 million international units (MIU)
solution for injection in cartridge
Interferon alfa-2a
Read all of this leaflet carefully
before you start using this medicine.
 Keep this leaflet. You may need
to read it again.
 If you have any further questions,
ask your doctor or pharmacist.
 This medicine has been prescribed
for you. Do not pass it on to others.
It may harm them, even if their
symptoms are the same as yours.
 If any of the side effects become
serious, or if you notice any side effects
not listed in this leaflet, please tell
your doctor or pharmacist.

Do not use Roferon-A if you are
pregnant, think you may be pregnant,
or are planning to become pregnant,
unless your doctor tells you to. This is
because Roferon-A may affect your baby.
It is important that you and your partner
use an effective method of birth control
(contraception) while you are being
treated with Roferon-A.
When Roferon-A is used in combination
with ribavirin, both male and female
patients must take special precautions
in their sexual activity if there is any
chance for pregnancy to occur as ribavirin
can be very damaging to an unborn baby:
- if you are a woman of childbearing
age who is taking Roferon-A in
combination with ribavirin, you must
have a negative pregnancy test before
treatment, each month during therapy
and for the 4 months after treatment
is stopped. You and your partner must
each use an effective contraceptive
during the time you are taking
the treatment and for 4 months after
stopping treatment. This can be
discussed with your doctor.
- if you are a man who is taking
Roferon- A in combination with ribavirin,
do not have sex with a pregnant
women unless you use a condom. This
will lessen the chance for ribavirin
to be left in the woman’s body. If your
female partner is not
pregnant now but is
of childbearing age,
she must be tested for
pregnancy each
month during
treatment and for 7 months after
treatment has stopped. You and your
partner must each use an effective
contraceptive during the time you are
taking the treatment and for the 7
months after stopping treatment. This
can be discussed with you doctor.

6. Further information

1. What Roferon-A is
and what it is used for
Roferon-A contains an antiviral agent
called interferon alfa-2a which is similar
to a natural substance produced by the
body to protect against viral infections,
tumors and foreign substances that
may invade the body. Once Roferon-A
has detected and attacked a foreign
substance, it alters it by slowing,
blocking, or changing
its growth or function.
Roferon-A is used
to treat the following:
 Viral infections, such as chronic
hepatitis B and C.
 Cancers of the blood (cutaneous T-cell
lymphoma, hairy cell leukaemia
and chronic myelogenous leukaemia).
 Some other forms of cancer (renal
cell carcinoma, AIDS-related Kaposi’s
sarcoma, follicular non-Hodgkin’s
lymphoma and malignant melanoma).
If you are not sure why you have been
prescribed Roferon-A, you should discuss
your illness and its treatment with
your doctor.

Ask your doctor or pharmacist for advice
before taking any medicine. It is not
known whether this product is present
in human milk. Therefore, discuss with
your doctor whether you should suspend
breast-feeding or discontinue Roferon-A.
In combination therapy with ribavirin,
take notice of the respective informing
texts of ribavirin containing medicinal

2. Before you use Roferon-A

 if you are allergic (hypersensitive)
to interferon alfa-2a or any of the other
ingredients of Roferon-A (listed
in Section 6: Further information).
 if you suffer or have suffered from
heart disease.
 if you have a severe kidney or liver
 if you have a liver disease or liver
 if you have a bone marrow disorder.

drowsy, tired or confused while using
Important information about
some of the ingredients of Roferon-A
Roferon-A contains benzyl alcohol
therefore it must not be given to
premature babies or newborns. It may
cause toxic or allergic reactions in infants
and children up to 3 years old.
The product contains less than 1 mmol
sodium (23 mg) per 0.5 ml, i.e. essentially
“sodium free”.

Roferon-A is not recommended
for use in children except on the
advice of your doctor. ‘Gasping syndrome’
(a serious condition in children up to
3 years old), has been linked with benzyl
alcohol. Benzyl alcohol is an inactive
ingredient in Roferon-A. Roferon-A
is therefore not a suitable medicine for
young children (including premature
babies, newborns or infants).

3. How to use Roferon-A
Always use Roferon-A exactly as your
doctor has told you.
Roferon-A can be given by your doctor
or nurse, or your doctor or nurse may
teach you how to inject yourself with
Roferon-A. Do not try to inject yourself
with Roferon-A unless you have received
training. You should check with your
doctor or nurse if you are not sure.

For some diseases, Roferon-A may
be used in combination with other drugs.
In such cases any additional restrictions
on the use of Roferon-A will be
explained to you by your doctor.

The cartridge in combination with
the Roferon-Pen is for the injection
of Roferon-A beneath your skin
(subcutaneous). The Roferon-Pen
user manual contains detailed
instruction for use of the Roferon-Pen /
cartridge combination. Read this manual
carefully before use.
Roferon-A cartridges are for multidose
use. This means that multidose injections
are possible with this presentation.
You should write the date of first use
on the label provided with the cartridge
and use within 28 days of this date.
Your doctor or nurse will show you an
“aseptic technique” that will allow you
to administer the required amount
of Roferon-A safely. A new sterile needle
must be used each time you administer
a dose.

Take special care with Roferon-A:
Tell your doctor:
 if you have mental problems
(psychiatric difficulties) or have ever
had a mental (psychiatric) illness.
 if you have psoriasis (a disease
of recurring dry, patchy, scaly skin
 if you have kidney, heart or liver
 if you have ever had an autoimmune
disease, e.g. thyroid problems,
vasculitis (inflammation of the blood
 if you have had an organ transplant
(such as kidney) or bone marrow
transplant, or have one planned in
the near future.
 if you are or may be pregnant.
 if you have a low blood cell count.
 if you have diabetes (a disease
resulting from high sugar level in your
 if you have any other problems
with your blood .
 if you are being treated for chronic
hepatitis C.
 if you are also infected with HIV and
being treated with anti-HIV medicinal
 if you are taking any other medicines
(including those not prescribed by your

Roferon-A dosing
Your doctor will decide the best dose
for you. The amount of Roferon-A you
need will depend on why you are
being treated and the side effects you
Your dose should not normally be more
than 36 Million International Units
(MIU) per day.
If you think the effect of your medicine
is too weak or too strong talk to your
doctor. Do not change the amount you
take before talking to your doctor.

Tell your doctor if you have a blood
disorder or suffer from diabetes. Your
doctor may take samples of your blood
at intervals to check its composition,
which may change during treatment.
If needed your doctor may adjust the dose
of your treatment with Roferon-A and
any other treatments you are receiving
at the same time.

Usual Initial Dosage
Hairy Cell Leukaemia 3 MIU daily for
16 - 24 weeks.
Chronic Myelogenous Leukaemia
The dose will normally be increased
from 3 MIU to 9 MIU taken once a day
over an initial treatment period
of 12 weeks.

Using other medicines
Please tell your doctor or pharmacist
if you are taking or have recently taken
any other medicines including medicines
obtained without a prescription.
The effects of those drugs could either
be increased, decreased, or altered when
administered concomitantly with
interferons. In particular the plasma
concentration of theophylline, an asthma
drug from the xanthine family, can be
increased when it is administered
concomitantly with interferon and may
request a dosage adjustment.

Cutaneous T-Cell Lymphoma
The dose will normally be increased
from 3 MIU to 18 MIU taken once a day
over an initial treatment period
of 12 weeks.
AIDS-related Kaposi’s Sarcoma

Therapy (HAART), an HIV treatment.

Combination with bevacizumab (Avastin)
9 MIU under the skin (subcutaneously)
three times a week until your disease
progresses or for up to 1 year.

If you are receiving HAART, the addition
of Roferon-A and Ribavirin may increase
your risk of lactic acidosis or liver failure.
Your doctor will monitor you for signs
and symptoms of these conditions. Please
read the Ribavirin Package Leaflet.

Chronic Hepatitis B
2.5 - 5 MIU/square metre body surface
area three times a week for 4 - 6 months.

Tests and investigations:
If you are going to have a blood test,
you should tell the doctor or nurse
performing the test that you are taking
Roferon-A. In some uncommon or rare
cases, Roferon-A may affect the results
of these tests.

Chronic Hepatitis C
3 - 6 MIU three times a week
for 6 months.
Follicular Non-Hodgkin’s Lymphoma
(with chemotherapy)
6 MIU/square metre body surface area

Breathlessness, cough and vasculitis
(inflammation of the blood vessels) have
been reported rarely.

Other important instructions

Liver and kidney disorders:
Sometimes, mild effects on your liver
may occur, but these will not normally
require a change in dosage. In rare cases,
Roferon-A may cause the liver to work
less well than usual and may result
in severe liver abnormalities, including
liver failure and hepatitis.

Your doctor will tell you when
to stop using Roferon-A. Some
illnesses may require treatment over
a period of several years.
If you use more Roferon-A than
you should:
