How is mepolizumab given?
Your doctor may perform blood tests to make sure you do not have conditions that would prevent you from safely using mepolizumab.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Mepolizumab is not a rescue medicine for asthma attacks. Use only fast-acting inhalation medicine for an attack. Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.
Mepolizumab is injected under the skin, usually once every 4 weeks. A healthcare provider may teach you how to properly use the medication by yourself. Follow all directions on your prescription label
Mepolizumab powder must be mixed with a liquid (diluent) before using it. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Gently swirl but do not shake the mixed medicine. Prepare an injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
Store the vial (bottle) in its original carton at room temperature. Protect from light and do not freeze.
Store the prefilled syringe or autoinjector in the original carton in a refrigerator. Do not freeze or shake the medicine. After removing the medicine from the carton, you must use the syringe or autoinjector within 8 hours.
You may store the prefilled syringe or autoinjector in the unopened carton at room temperature for up to 7 days. Throw away a syringe or autoinjector left out of the refrigerator for more than 7 days.
Each vial, prefilled syringe, or autoinjector is for one use only. Throw it away after one use, even if there is still medicine left inside.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
