What Arzerra is used for

Arzerra contains ofatumumab, which belongs to a group of medicines called monoclonal antibodies.

Arzerra is used to treat chronic lymphocytic leukaemia (CLL). CLL is a cancer of the blood which affects a type of white blood cell called a lymphocytes. The lymphocytes multiply too quickly and live too long, so there are too many of them circulating in your blood.

The disease can also affect other organs in your body. The antibody in Arzerra recognises a substance on the surface of lymphocytes and binds to them, decreasing the amount of lymphocytes in the body.

Your doctor may have prescribed Arzerra for another reason.

This medicine is available only with a doctor’s prescription.

ARZERRA is not recommended for use in children and adolescents, under the age of 18 years.

Arzerra is not addictive.

Before you are given Arzerra

When you must not receive Arzerra

You must not receive Arzerra if you have ever had a:

  • Severe allergic (hypersensitive) reaction to Arzerra (ofatumumab).
  • An allergic reaction to any of the ingredients listed toward the end of this leaflet.
    See “Ingredients” on Page 4.

Some of the symptoms of an allergic reaction may include:

  • Shortness of breath
  • Wheezing or difficulty breathing
  • Swelling of the face, lips, tongue or other parts of the body
  • Rash, itching or hives on the skin

Check with your doctor if you think that any of these reactions may apply to you.

If you are not sure whether you should start to be given this medicine, talk to your doctor.

Tell your doctor if

Before you are given Arzerra your doctor needs to know if you have:

  • Lung disease
  • Had heart problems
  • Ever had hepatitis B (a liver disease).
    Arzerra could cause your hepatitis B to become active again. Your doctor may treat you with a suitable anti-viral medicine to help prevent this.
  • Ever had an Infusion reaction.
    See “Infusion reactions” on Page 2 for more information about this.
  • Progressive multifocal leukoencephalopathy (PML), a rare is a disease that attacks part of your brain.
    See “Progressive multifocal leukoencephalopathy (PML)” in the following text.

Tell your doctor if you think any of these may apply to you. You may need extra check-ups while you are being treated with Arzerra.

Infusion reactions

Medicines of this type (monoclonal antibodies) are given into a vein (intravenously) as an infusion (a drip) over several hours. These medicines can cause infusion reactions (side effects) when they are injected into your body. You will be given medicines such as anti-histamines, steroids or pain relievers to help reduce any reaction (see also ‘Side effects’).

Progressive multifocal leukoencephalopathy (PML)

Medicines like Arzerra may cause a serious and life threatening brain condition called progressive multifocal leukoencephalopathy (PML). This condition damages myelin, the fatty substance which protects nerves in the brain.

Tell your doctor immediately if you have any of these symptoms: memory loss, trouble with thinking, difficulty with walking, or loss of vision. If you had these symptoms prior to treatment with Arzerra, tell your doctor immediately about any changes in these symptoms.

Vaccination and Arzerra

If you are having any vaccinations tell your doctor, or the person giving you the vaccine, that you are being treated with Arzerra. Your response to the vaccine may be weakened.

Taking other medicines

Tell your doctor, health care professional, or pharmacist if you are taking any other medicines, have taken any recently, or if you start new ones. This includes herbal medicines and other medicines you’ve bought without a prescription. These might interact with Arzerra.


Tell your doctor if you are pregnant or think you could be, before you are given Arzerra. There is limited information about the safety of Arzerra in pregnant women. Your doctor will consider the benefit to you and the risk to your baby of taking Arzerra while you are pregnant.

Use a reliable method of contraception to prevent pregnancy while you’re being treated with Arzerra, and for at least six months after your last infusion.


It is not known whether the ingredients in Arzerra pass into human breast milk.

If you are breast-feeding, you must check with your doctor before you take Arzerra.

Patients on controlled sodium diets

Arzerra contains 34.8 mg sodium in each 300 mg dose and 232 mg sodium in each 2000 mg dose.

If you are on a controlled sodium diet, you and your doctor or nurse need to take this into account.

Driving and using machines

Arzerra is unlikely to affect your ability to drive or use machines.

How Arzerra is used

Arzerra is to be administered by a physician or healthcare professional only.

Arzerra must not be mixed with, or administered with other medicinal products or intravenous solutions.

If you have any questions on the use of this product, ask the doctor, nurse, or healthcare professional who is giving Arzerra to you.

How much Arzerra will be given to you

The usual dose for the first infusion is 300 mg. This dose will usually be increased to 1000 mg or 2000 mg for the remaining infusions.

How it is given

Arzerra is given into a vein (intravenously) as an infusion (a drip) over several hours.

If you have not been previously treated for CLL you will usually have a maximum of 13 infusions. You will be given an infusion followed by a second infusion 7 days later. The remaining infusions will then be given once a month for up to 11 months.

If you have been previously treated for CLL, you will usually have a course of 12 infusions. You will be given an infusion once a week for eight weeks. This is followed by a four- to five-week gap. The remaining infusions will be given once a month for four months.


Before each infusion of Arzerra, you will be given medicines which help to reduce any infusion reactions. These may include anti-histamines, steroids and pain relievers. You will be checked closely and if you do have any reactions these will be treated.
