Reslizumab injection may cause serious or life-threatening allergic reactions. You may experience an allergic reaction while you are receiving the infusion or for a short period of time after the infusion has finished.
You will receive each injection of reslizumab in a doctor's office or medical facility. You will stay in the office for some time after you receive the medication so your doctor or nurse can watch you closely for any signs of an allergic reaction. Tell your doctor if you experience any of the following symptoms: wheezing or difficulty breathing; shortness of breath; flushing; paleness; fainting, dizziness, or lightheadedness; confusion; fast heartbeat; itching; hives, difficulty swallowing; nausea or stomach discomfort; or swelling of your face, lips, mouth, or tongue.
Talk to your doctor about the risk of using reslizumab.
Why is this medication prescribed?
Reslizumab injection is used along with other medications to treat asthma in certain people. Reslizumab is in a class of medications called monoclonal antibodies. It works by reducing a certain type of white blood cell that may contribute to your asthma.
How should this medicine be used?
Reslizumab comes as a solution (liquid) that is given intravenously (into a vein) by a doctor or nurse in a healthcare setting. It is usually given once every 4 weeks. It will take about 20 to 50 minutes for you to receive your dose of reslizumab.
Reslizumab injection is not used to treat a sudden attack of asthma symptoms. Your doctor will prescribe a short-acting inhaler to use during attacks. Talk to your doctor about how to treat symptoms of a sudden asthma attack. If your asthma symptoms get worse or if you have asthma attacks more often, be sure to talk to your doctor.
Do not decrease your dose of any other asthma medication or stop taking any other medication that has been prescribed by your doctor unless your doctor tells you to do so.
