What DARZALEX SC is used for

DARZALEX SC 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 abnormal blood cells in your body, so your immune system can destroy them.
DARZALEX SC is used to treat adults with multiple myeloma (cancer of the bone marrow).
DARZALEX SC is also used to treat adults with AL amyloidosis (also known as light chain amyloidosis, a type of blood disorder). In AL amyloidosis, abnormal blood cells make excessive amounts of abnormal proteins that deposit in various organs, causing these organs to not function properly.
Your doctor may have prescribed DARZALEX SC for another reason.
Ask your doctor if you have any questions about why DARZALEX SC has been prescribed for you.
This medicine is available only with a doctor's prescription.

Before you are given DARZALEX SC

When you must not use it:

Do not use DARZALEX SC if:
you know you are allergic (hypersensitive) to daratumumab or other ingredients of DARZALEX SC. 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 SC 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 SC.

Both men and women receiving DARZALEX SC and their partners must use a reliable method of contraception during and for 3 months after ceasing treatment with DARZALEX SC.
Tell your doctor if you are breastfeeding or intend to breastfeed.
It is not known whether DARZALEX SC 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 SC 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 SC.

Be careful not to cut yourself when you are using sharp objects such as a razor or nail cutters.

Your doctor may decide not to use DARZALEX SC if you have a strong reaction after the injection.
In some cases you may have a severe allergic reaction which may include a swollen face, lips, mouth, tongue or throat, difficulty swallowing or breathing or an itchy rash (hives).
Tell your doctor or nurse right away if you get any of the infusion-related reactions or allergic reactions listed in the Side Effects section.
If you get infusion-related reactions, you may need other medicines to treat your symptoms, or the injections may need to be stopped. When these reactions go away or get better, the injection can be started again.
