Serious allergic reactions can happen during or even several days after your treatment. Careful monitoring by your doctor may decrease your risk. If you have a serious reaction, your treatment may be stopped. Get medical help right away if you have swelling of face/tongue/throat, trouble breathing, rash, or hives.
Use this medication regularly to get the most benefit from it. To help you remember, mark your calendar to keep track of when to receive the next dose.
If you are regularly using a corticosteroid medication, you should not stop using it unless directed by your doctor. Some conditions (such as asthma, allergies) may become worse when the drug is suddenly stopped. If you suddenly stop using the corticosteroid medication, you may also have withdrawal symptoms (such as weakness, weight loss, nausea, muscle pain, headache, tiredness, dizziness). To help prevent withdrawal, your doctor may slowly lower the dose of your corticosteroid medication after you begin using benralizumab. Tell your doctor or pharmacist right away if you have withdrawal.
Tell your doctor if you do not get better or if you get worse.
