Vumerity (Generic Diroximel Fumarate)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Diroximel fumarate is used to treat adults with relapsing forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours), relapsing-remitting forms (course of disease where symptoms flare up from time to time), or secondary progressive forms (course of disease where relapses occur more often). Diroximel fumarate is in a class of medications called Nrf2 activators. It works by decreasing inflammation and preventing nerve damage that may cause symptoms of multiple sclerosis.
How should this medicine be used?
Diroximel fumarate comes as a delayed-release (releases the medication in the intestine to prevent breakdown of the medication by stomach acids) capsule to take by mouth. It is usually taken twice daily. Take diroximel fumarate at around the same times 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 diroximel fumarate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Diroximel fumarate may be taken with or without food. To reduce the chance of flushing (facial redness) during your treatment, you can take a nonenteric coated aspirin (325 mg or less) 30 minutes before taking diroximel fumarate or you can take it with food. However, do not take diroximel fumarate with a high-fat, high-calorie meal or snack; the meal or snack must contain less than 700 calories and less than 30 grams of fat.
Do not drink alcoholic beverages at the same time you take diroximel fumarate.
Swallow the capsules whole; do not chew or crush them. Do not open the capsules or sprinkle the contents on food.
Your doctor will probably start you on a low dose of diroximel fumarate and increase your dose after 7 days.
Diroximel fumarate may help to control multiple sclerosis, but will not cure it. Continue to take diroximel fumarate even if you feel well. Do not stop taking diroximel fumarate without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor may order a blood test before you begin your treatment and may order certain lab tests during your treatment to check your body’s response to diroximel fumarate.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
