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
● Cancers of the blood (cutaneous T-cell
lymphoma, hairy cell leukaemia and
chronic myelogenous leukaemia).
● Some other forms of cancer (renal cell
carcinoma, 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.

2. What you need to know before
you use Roferon-A
Do not use Roferon-A:
● if you are allergic to interferon alfa-2a or
any of the other ingredients of this medicine
(listed in Section 6).
● if you suffer or have suffered from heart
● if you have a severe kidney or liver
● if you have a bone marrow disorder.
● if you suffer from seizures e.g. epilepsy
and/or other central nervous system
● if you have a liver disease or liver cirrhosis
● if you are or have recently been treated with
medication for chronic liver disease that
weakens your immune response.
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).
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

Tell your doctor if you have a blood disorder
or suffer from diabetes. Your doctor may take

any other treatments you are receiving at the
same time.

3. How to use Roferon-A
Always use this medicine exactly as your

pharmacist if you are not sure.
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

Roferon-A pre-filled syringes are used to give
an injection beneath your skin (subcutaneous).
See section 7 for detailed instructions.
The pre-filled syringes are for single use only.
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 suffer.
Your dose should not normally be more than
36 million International Units (IU) 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.
The recommended dose is:
Hairy Cell Leukaemia
3 million IU daily for 16‑24 weeks.
Chronic Myelogenous Leukaemia
The dose will normally be increased from
3 million IU to 9 million IU taken once a day
over an initial treatment period of
12 weeks.
Cutaneous T-Cell Lymphoma
The dose will normally be increased from
3 million IU to 18 million IU taken once a day
over an initial treatment period of
12 weeks.
Renal Cell Carcinoma
Combination with vinblastine
The dose will normally be increased from
3 million IU to 18 million IU taken three
times a week over an initial treatment
period of 12 weeks.
Combination with bevacizumab (Avastin)
9 million IU under the skin
(subcutaneously) three times a week until
your disease progresses or for up to 1 year.
Chronic Hepatitis B
2.5‑5 million IU/square metre body surface
area three times a week for 4‑6 months.
Chronic Hepatitis C
3‑6 million IU three times a week for
6‑12 months.
Follicular Non-Hodgkin’s Lymphoma (with
6 million IU/square metre body surface area
from day 22 to day 26 of each 28-day cycle
Malignant Melanoma
3 million IU three times a week for 18 months.
If you respond well to initial treatment with
Roferon-A, your doctor may decide that you
should continue treatment for a longer period
of time (maintenance therapy) and will change
your dosage accordingly.
Combination therapy with Ribavirin in chronic
hepatitis C
When taking Roferon-A and Ribavirin at the
same time, please follow the dosage regimen
recommended by your doctor.
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
Contact your doctor, pharmacist or nearest
hospital immediately.

If you forget to use Roferon-A
Do not take a double dose to make up for a
forgotten dose.

Other medicines and Roferon-A

If you stop using Roferon-A

Tell your doctor or pharmacist if you are
taking, have recently taken or might take any
other medicines. The effects of those
medicines could either be increased,
decreased, or altered when administered at the
same time as interferons. In particular the
plasma concentration of theophylline, an
asthma medicine from the xanthine family, can
be increased when it is administered at the
same time as interferon and may require a
dosage adjustment.

Contact your doctor or pharmacist as soon as

Patients who also have HIV infection: Lactic
acidosis and worsening liver function are side
effects associated with Highly Active AntiRetroviral Therapy (HAART), an HIV
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.
Blood tests. 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

Pregnancy and fertility
Do not use Roferon-A if you are pregnant,
think you may be pregnant, or are planning to
have a baby, 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.
