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.
