Pharmacologic Class: Monoclonal Antibody
Ofatumumab injection is used to treat a type of cancer of the white blood cells called chronic lymphocytic leukemia (CLL). This medicine is used in patients with CLL who have already been treated with other medicines (e.g., alemtuzumab, fludarabine) that did not work well.
Ofatumumab interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal body cells may also be affected by ofatumumab, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor. Some unwanted effects, such as a skin rash, may not be serious but may cause concern. Some of the unwanted effects do not occur until months or years after the medicine is used.
Before you begin treatment with ofatumumab, you and your doctor should talk about the good this medicine will do as well as the risks of using it.
This medicine is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur.

You will receive this medicine while you are in a hospital or cancer treatment center. A nurse or other trained health professional will give you this medicine. This medicine is given through a needle placed in one of your veins.
Ofatumumab needs to be given slowly, so the needle will remain in place for at least an hour. You may also receive medicines to help prevent allergic reactions.
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and to check for unwanted effects. Blood tests may be needed to check for unwanted effects.
This medicine may cause chest pain; fever; chills; itching; hives; flushing of the face; rash; dizziness, fainting, or lightheadedness; troubled breathing; or swelling of the face, tongue, and throat within a few hours after you receive it. Check with your doctor or nurse right away if you have any of these symptoms.
Ofatumumab can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
This medicine may increase your risk of developing a serious and rare brain infection called progressive multifocal leukoencephalopathy (PML). Check with your doctor right away if you are having more than one of these symptoms: vision changes, loss of coordination, clumsiness, memory loss, difficulty speaking or understanding what others say, and weakness in the legs.
Check with your doctor immediately if you have any symptoms of liver problems including skin and eyes turning yellow, dark brown-colored urine, right-sided abdominal or stomach pain, fever, or severe tiredness.
While you are being treated with ofatumumab, do not have any immunizations (vaccines) without your doctor's approval. Live virus vaccines should not be given with this medicine or soon after you receive it.
