Ponesimod

pronounced as (poe nes' i mod)

Why is this medication prescribed?

Ponesimod is used to prevent episodes of symptoms and slow the worsening of disability in adults who have 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: Ponesimod 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.

  • clinically isolated syndrome (CIS; first nerve symptom episode that lasts at least 24 hours),
  • relapsing-remitting disease (course of disease where symptoms flare up from time to time),
  • active secondary progressive disease (later stage of disease with continuous worsening of symptoms.)

How should this medicine be used?

Ponesimod comes as a tablet to take by mouth. It is usually taken once a day with or without food. Take ponesimod 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 ponesimod exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

Your doctor will probably start you on a low dose of ponesimod and gradually increase your dose for the first 15 days.

Ponesimod may cause the heartbeat to slow, especially during the first 4 hours after you take your first dose. You will take your first dose of ponesimod in your doctor's office or another medical facility. You will receive an electrocardiogram (ECG; test that records the electrical activity of the heart) before you take your first dose and again 4 hours after you take the dose. You will need to stay at the medical facility for at least 4 hours after you take the medication so that you can be monitored. You may need to stay at the medical facility for longer than 4 hours or overnight if you have certain conditions or take certain medications that increase the risk that your heartbeat will slow or if your heartbeat slows more than expected or continues to slow after the first 4 hours. You may also need to stay at a medical facility for at least 4 hours after you take your second dose if your heartbeat slows too much when you take your first dose. Tell your doctor if you experience dizziness, tiredness, chest pain, or slow or irregular heartbeat at any time during your treatment.

Ponesimod may help control multiple sclerosis but will not cure it. Do not stop taking ponesimod without talking to your doctor.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ponesimod 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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

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). If your medication came with a desiccant packet (small packet that contains a substance that absorbs moisture to keep the medication dry), leave the packet in the bottle but be careful not to swallow it.

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.

In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Symptoms of overdose may include:

  • slowed or irregular heartbeat

What other information should I know?

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests and 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 ponesimod.

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.
