What is reslizumab?

Reslizumab is used along with other medicines to help manage severe asthma in adults.

Reslizumab works on your immune system by lowering the levels of a specific type of white blood cell that can contribute to asthma symptoms.

Reslizumab may also be used for reasons not mentioned in this medication guide.

How is reslizumab given?

Before you start treatment with reslizumab, your doctor may do tests to check your white blood cell levels.

Reslizumab is given as an infusion into a vein, usually once every 4 weeks. A healthcare provider will give you this infusion.

This medicine must be given slowly, and the infusion can take 20 to 50 minutes to finish.

You will be monitored closely for a short time after each infusion to ensure you do not have an allergic reaction.

If you are also using a steroid medication, you should not stop taking it suddenly. Follow your doctor's instructions about reducing your dose gradually.

Reslizumab is not a rescue medicine for asthma attacks. Seek medical help if your breathing problems worsen quickly, or if you think your asthma medications are not working as well as they should.

Use all asthma medications as directed. Your dose may need to change due to surgery, illness, stress, or a recent asthma attack. Do not change your dose or dosing schedule without your doctor's advice. Inform your doctor if any of your medicines seem to stop working.

Before taking this medicine

You should not be treated with reslizumab if you are allergic to it.

Tell your doctor if you have ever had a parasite infection (such as roundworms or tapeworms).

Using reslizumab may increase your risk of developing cancer. Ask your doctor about this risk.

Tell your doctor if you are pregnant. It is not known whether reslizumab will harm an unborn baby. However, having uncontrolled asthma during pregnancy may cause premature birth, a low birth weight baby, or complications such as eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating asthma may outweigh any risks to the baby.

It may not be safe to breastfeed while using reslizumab. Ask your doctor about any risk.
