Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about DARZALEX Concentrate for Solution
for Infusion. It does not contain all the available information. It does not take
the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you being
given DARZALEX against the benefits this medicine is expected to have for you.
If you have any concerns about being given DARZALEX ask your doctor.
Keep this leaflet while you are being treated with DARZALEX.
You may need to read it again.
What DARZALEX is used for
DARZALEX is an anti-cancer medicine and contains the active substance daratumumab.
This belongs to a group of medicines called “monoclonal antibodies”. One of the ways
monoclonal antibodies work is by attaching themselves to specific cancer cells in
your body, so your immune system can destroy them.
DARZALEX is used to treat adults with multiple myeloma (cancer of the bone marrow).
Your doctor may have prescribed DARZALEX for another reason.
Ask your doctor if you have any questions about why DARZALEX has been prescribed for
you.
This medicine is available only with a doctor's prescription.
Before you are given DARZALEX
When you must not use it:
Do not use DARZALEX if:
you know you are allergic (hypersensitive) to daratumumab or other ingredients of
DARZALEX. See Product Description at the end of this leaflet for a list of ingredients.
Symptoms of an allergic reaction may include rash, itching or hives on the skin, shortness
of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or
other parts of the body.
DARZALEX should not be given to children or young people below 18 years of age. This
is because it is not known how the medicine will affect them.
Before you start to use it:
Tell your doctor if you have or have had any medical conditions, especially the following:
blood disorder with a low level of white blood cells or platelets. This disorder may
become worse during treatment with DARZALEX.
Hepatitis B infection
DARZALEX could cause hepatitis B virus to become active again. Your doctor will check
you for signs of this infection before, during and for some time after treatment with
DARZALEX.
Tell your doctor if you are pregnant or intend to become pregnant.
Like most medicines used to treat cancer, DARZALEX is not recommended for use during
pregnancy.
Tell your doctor if you are trying to make your partner pregnant.
Both men and women receiving DARZALEX and their partners must use a reliable method
of contraception during and for 3 months after ceasing treatment with DARZALEX.
Tell your doctor if you are breastfeeding or intend to breastfeed.
It is not known whether DARZALEX passes into breast milk. Therefore there is a possibility
that the breastfed baby may be affected.
If you wish to restart breastfeeding after your DARZALEX treatment, you must discuss
this with your doctor or nurse, who will tell you when it is safe to do so.
If you have not told your doctor about any of the above, tell them before you start
treatment with DARZALEX.
Taking other medicines:
Tell your doctor if you are taking any other medicines, including vitamins and herbal
supplements and including medicines you can buy with or without a prescription from
a pharmacy, supermarket or health food shop.
These medicines may be affected by DARZALEX or may affect how well DARZALEX works.
Your doctor or pharmacist can tell you what to do if you are using any other medicines.

While you are using DARZALEX
Things you must do:
Be sure to keep all your doctor's appointments so your progress can be checked.
Your doctor will want to do some blood, urine and other tests from time to time to
check on your progress and detect any unwanted side effects.
Keep follow up appointments with your doctor.
It is important to have your follow-up doses of DARZALEX at the appropriate times
to get the best effects from your treatment.
Be sure to follow your doctor's instructions about other medicines you should take,
and other things you should do.
Tell any other doctors, dentists and pharmacists who are treating you that you are
having DARZALEX.
If you are about to be started on any new medicines, tell your doctor, dentist or
pharmacist that you are having DARZALEX.
If you become pregnant or your partner becomes pregnant while being given DARZALEX,
tell your doctor immediately.
If you need to have a blood test, tell the person doing the test that you are using
DARZALEX.
Decreased blood cell counts
DARZALEX can decrease white blood cell counts which help fight infections, and blood
cells called platelets which help to clot blood.
Tell your doctor if you develop fever or if you have signs of bruising or bleeding.
The following precautions should be taken to reduce your risk of infection or bleeding:
Avoid people who have infections. Check with your doctor immediately if you think
you may be getting an infection, or if you get a fever, chills, cough, hoarse throat,
lower back or side pain or find it is painful or difficult to urinate.
Be careful when using a toothbrush, toothpick or dental floss. Your doctor, dentist,
nurse or pharmacist may recommend other ways to clean your teeth and gums. Check with
your doctor before having any dental work.
Be careful not to cut yourself when you are using sharp objects such as a razor or
nail cutters.
Blood transfusions
If you need a blood transfusion, you will have a blood test first to match your blood
type. DARZALEX can affect the results of this blood test. Tell the person doing the
test that you are using DARZALEX.
Hepatitis B
If you have ever had a hepatitis B infection, DARZALEX could cause hepatitis B virus
to become active again. Your doctor will check you for signs of this infection before,
during and for some time after treatment with DARZALEX.
Tell your doctor right away if you get increasingly tired or get yellowing of your
skin or white part of your eyes.
Infusion-related reactions
Before and after each infusion of DARZALEX, you will be given medicines which help
to lower the chance of infusion-related reactions (see “Medicines given during treatment
with DARZALEX”). Some serious allergic reactions and other severe infusion related
reactions have resulted in death. These reactions can happen during the infusion or
in the 3 days after the infusion.
Tell your doctor or nurse right away if you get any of the infusion-related reactions
listed at the top of the Side Effects section.
If you get infusion-related reactions, you may need other medicines, or the infusion
may need to be slowed down or stopped. When these reactions go away, or get better
the infusion can be started again.
These reactions are most likely to happen with the first infusion. If you have had
an infusion-related reaction once it is less likely to happen again. Your doctor may
decide not to continue DARZALEX if you have a strong infusion-related reaction.
Things to be careful of
Be careful driving or operating machinery until you know how DARZALEX affects you.
DARZALEX may cause tiredness and other effects in some people. Make sure you know
how you react to DARZALEX before you drive a car, operate machinery, or do anything
else that could be dangerous if you have side effects.
Side Effects
Like all medicines, DARZALEX can cause side effects, although not everybody gets them.
Some of these effects may be serious. However, there may be ways to reduce the discomfort
of these effects. You may need medical treatment if you get some of the side effects.
Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well
while you are being treated with DARZALEX.
Do not be alarmed by the following lists of side effects. You may not experience any
of them.
Ask your doctor or pharmacist to answer any questions you may have.
