Deflazacort is used to treat Duchenne muscular dystrophy (DMD; a progressive disease in which the muscles do not function properly) in adults and children 2 years of age and older. Deflazacort is in a class of medications called corticosteroids. It works by reducing inflammation (swelling) and by changing the way the immune system works.
Deflazacort comes as a tablet and a suspension (liquid) to take by mouth. It is usually taken once a day with or without food. Take deflazacort at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take deflazacort exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
