Warning

Blinatumomab may cause certain serious (sometimes fatal) side effects, including cytokine release syndrome-CRS and infusion reactions. Symptoms may include fever, chills, headache, nausea, vomiting, stomach/abdominal pain, trouble breathing, skin rash, weakness, or low blood pressure. Blinatumomab can also cause serious brain, spinal cord, and nerve disorders with symptoms such as headache, trouble sleeping, seizures, confusion, loss of consciousness, difficulty with swallowing/facial movements, or speech and balance problems. Tell your doctor right away if you develop any of these symptoms.

You may be given this medication in a hospital or clinic so your doctor can watch for these serious side effects and provide treatment if needed. If you have side effects, your doctor may temporarily stop or slow down your treatment with this medication. Also, your doctor may prescribe other medications before you receive blinatumomab to decrease the risk of side effects.

Uses

This medication is used to treat a certain type of cancer (acute lymphocytic leukemia-ALL). Blinatumomab belongs to a class of drugs known as monoclonal antibodies. It works by slowing or stopping the growth of cancer cells.

How to use

See also Warning section.

Read the Medication Guide provided by your pharmacist before you start using blinatumomab and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

The dosage and treatment schedule are based on your medical condition, weight, and response to treatment. To reduce your risk of side effects, your doctor may prescribe other medications (such as dexamethasone) before each treatment to help reduce side effects. Also, your doctor may start this medication at a low dose and gradually increase your dose.

This medication is given by slow injection (infusion) into a vein as directed by your doctor. A special machine (infusion pump) is used for giving the injection, usually over 4 weeks (28 days), followed by a break (usually 2 weeks) during which you will not be given blinatumomab. After the break, your doctor will decide if you will be given another treatment cycle with this medication. In later treatment cycles, your breaks may be longer (8 weeks). Do not change the settings on the infusion pump since you might get the wrong dose. Ask your health care professional right away if you have any questions about the infusion pump.

Side effects

See also Warning section.

Nausea, heartburn, constipation, shaking (tremor), swelling ankles/feet/hands, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.

Blinatumomab sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as:

  • low back/side pain (flank pain)
  • signs of kidney problems (such as painful urination, pink/bloody urine, change in the amount of urine)
  • muscle spasms/weakness

This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as sore throat that doesn't go away, fever, chills, cough).

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

  • rash
  • itching/swelling (especially of the face/tongue/throat)
  • severe dizziness
  • trouble breathing

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
