Benralizumab injection may sometimes be given at home to patients who do not need to be in the hospital or clinic. If you are using this medicine at home, your doctor or nurse will teach you or your caregiver how to inject the medicine. Be sure that you understand exactly how to use this.
This medicine comes with a patient information leaflet. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems from the injections. Do not inject into scars, moles, or skin areas that are red, bruised, tender, hard, or not intact.
This medicine comes in two forms: a prefilled syringe (to be given by the doctor or other healthcare professional) and prefilled autoinjector or Fasenra® Pen™ (to be used by the patient or caregiver).
Allow 30 minutes for the prefilled autoinjector (Fasenra® Pen™) to warm up to room temperature. Do not warm it in any other way.
Use each Fasenra® Pen™ only one time. Do not save an open autoinjector.
Check the liquid in the Fasenra® Pen™. It should be clear and colorless or slightly yellow. Do not use this medicine if it is cloudy or if there are particles in it. Do not use the pen if it looks damaged or broken.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
