What is Emflaza?
Emflaza is a steroid that reduces inflammation in the body.
Emflaza is used to treat Duchenne muscular dystrophy in adults and children who are at least 5 years old.
Emflaza is not a cure for muscular dystrophy, but this medicine may improve muscle strength and slow the progression of disability.
Emflaza may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Before taking this medicine
You should not use Emflaza if you are allergic to it.
To make sure Emflaza is safe for you, tell your doctor if you have:
any type of bacterial, fungal, or viral infection;
high blood pressure, heart disease, or a history of stroke or blood clot;
cataracts, glaucoma, or herpes infection of the eyes;
a nerve-muscle disorder, such as myasthenia gravis;
a stomach or intestinal disorder;
a colostomy or ileostomy;
low bone mineral density; or
a problem with your thyroid, pituitary gland, or adrenal gland.
Long-term use of steroids may lead to bone loss (osteoporosis), especially if you smoke, if you do not exercise, if you do not get enough vitamin D or calcium in your diet, or if you have a family history of osteoporosis.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Deflazacort can pass into breast milk and may cause side effects in the nursing baby. Tell your doctor if you are breast-feeding.

How should I take Emflaza?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
You may take Emflaza with or without food.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
To make swallowing easier, you may crush the Emflaza tablet and sprinkle the medicine into a spoonful of applesauce. Swallow the mixture right away without chewing. Do not save it for later use.
Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine using only the dosing syringe provided. If you do not have this dosing syringe, ask your pharmacist for one.
To improve the flavor of Emflaza liquid, you may mix your measured dose with 3 to 4 ounces of milk or fruit juice (but not grapefruit juice). Drink this mixture right away and do not save it for later.
Emflaza can lower blood cells that help your body fight infections. This can make it easier for you to get sick from being around others who are ill. Serious and sometimes fatal infections may occur during treatment with this medicine.
If you use this medicine long-term, you may need frequent blood tests. Your blood pressure, vision, and bone density may also need to be checked.
Tell your doctor if you have any changes in weight. Emflaza doses are based on weight, and any changes may affect the dose.
If you need surgery, tell the surgeon ahead of time that you are using Emflaza.
You should not stop using Emflaza suddenly. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture and heat.
Throw away any Emflaza liquid that has not been used within 1 month after you first opened the bottle.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking Emflaza?
Grapefruit and grapefruit juice may interact with Emflaza and lead to unwanted side effects. Avoid the use of grapefruit products while taking this medicine.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medicine.
