Ozanimod

pronounced as (oh zan' i mod)

Why is this medication prescribed?

Ozanimod 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 disease (course of disease where symptoms flare up from time to time), or active secondary progressive disease (later stage of disease with continuous worsening of symptoms). It is also used to treat ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum) in adults. Ozanimod is in a class of medications called sphingosine l-phosphate receptor modulators. It works by decreasing the action of immune cells that may cause nerve damage.

How should this medicine be used?

Ozanimod comes as a capsule to take by mouth. It is usually taken with or without food once daily. Take ozanimod 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 ozanimod exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow capsules whole; do not open, chew, or crush them.

Your doctor will probably start you on a low dose of ozanimod and gradually increase your dose over the first week.

Ozanimod may cause the heartbeat to slow, especially during the first 8 days after you take your first dose. Tell your doctor if you experience dizziness, tiredness, lightheadedness, chest pain, or slow or irregular heartbeat, especially during the first 8 days after you take your first dose.

Ozanimod may help to control multiple sclerosis symptoms and ulcerative colitis, but does not cure them. Your doctor will watch you carefully to see how well ozanimod works for you. It is important to tell your doctor how you are feeling during your treatment.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ozanimod and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

  • tell your doctor if you have never had chickenpox and have not received the chickenpox (varicella) vaccine. Your doctor may order a blood test to see if you have been exposed to chickenpox. You may need to receive the chickenpox vaccine and then wait 1 month before beginning your treatment with ozanimod.
  • you should know that ozanimod may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking ozanimod. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.

Your doctor or dietitian will tell you which foods you must avoid completely, and which foods you may eat in small amounts. If you eat a food that is high in tyramine while taking ozanimod, contact your doctor.

What should I do if I forget a dose?

If you miss one or more doses during the first 14 days of treatment, talk to your doctor before you start taking it again. You will need to restart the medication at a lower dose and gradually increase the dose.

If you miss a dose after the first 14 days of treatment, continue your regular dosing schedule the next day. Do not take a double dose to make up for a missed one.

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. https://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 (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of emergency/overdose

What other information should I know?

Keep all appointments with your doctor and the laboratory. You will receive an electrocardiogram (ECG; test that records the electrical activity of the heart) before you take your first dose. Your doctor will also order certain lab tests, eye exams, and will monitor your blood pressure before and during your treatment to be sure that it is safe for you to begin taking or continue to take ozanimod.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

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.
