Edaravone injection is used to treat amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; a condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken). Edaravone injection is in a class of medications called antioxidants. It may work to slow the nerve damage associated with the worsening of ALS symptoms.

Edaravone injection comes as a solution (liquid) to be injected intravenously (into a vein) over 60 minutes by a health care professional in a doctor's office or medical facility. Initially, it is usually given once a day for the first 14 days of a 28-day cycle. After the first cycle, it is given once a day for the first 10 days of a 28-day cycle. Your doctor will decide how often you are to receive edaravone based on your body's response to this medication.

Edaravone may cause serious reactions during or after you receive your infusion. Your doctor may need to stop your treatment if you experience certain side effects. Tell your doctor if you experience any of the following symptoms: wheezing or difficulty breathing, shortness of breath, cough, fainting, flushing, itching, rash, hives, swelling of the throat, tongue, or face, throat tightness, or difficulty swallowing. It is important for you to tell your doctor how you are feeling during your treatment with edaravone injection. Call your doctor right away or get immediate emergency medical attention if you experience any of these symptoms after you leave your doctor's office or medical facility.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
