Proper Use

Drug information provided by: IBM Micromedex

A nurse or other trained health professional may give you this medicine. It is given through a needle placed under your skin, usually in the stomach, thighs, hips or upper arm. It must be given slowly, so the needle will have to stay in place using an infusion pump for at least 30 minutes (for 2 infusion sites) or at least 60 minutes (for 1 infusion site).

You or your caregiver may be trained to prepare and inject this medicine at home. Be sure that you understand how to use the medicine and the infusion pump.

It is very important that you understand the requirements of the Empaveli™ REMS program, and become familiar with the Empaveli™ medication guide and patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions. Ask your pharmacist for the medication guide and patient instructions if you do not have one.

If you use this medicine at home, you will be shown the body areas where the infusion can be given. Use a different body area each time you give yourself an injection. Keep track of where you give each injection to make sure you rotate body areas. This will help prevent skin problems. Do not inject into areas where the skin is tender, red, bruised, or hard or in areas with tattoos, scars, or stretch marks.

Allow this medicine to warm to room temperature for 30 minutes before using it. Do not warm it in any other way.

Check the liquid in the vial. It should be clear and colorless to slightly yellow solution. Do not use the medicine if the liquid is cloudy, discolored, or has particles in it.

  • Switching from ravulizumab to Empaveli™: You should start receiving Empaveli™ 4 weeks after your last dose of ravulizumab.
