Uses for siponimod

Siponimod is used to treat the relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. Siponimod will not cure MS, but it may slow some of the disabling effects and decrease the number of relapses of the disease.

Siponimod is available only with your doctor's prescription.

Before using siponimod

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For siponimod, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to siponimod or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of siponimod in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of siponimod in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution in patients receiving siponimod.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking siponimod, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using siponimod with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Siponimod should come with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.

If you are using siponimod and have certain heart conditions, your doctor may want you to stay in the medical facility for at least 6 hours after the first dose of siponimod and after starting it again if you miss 1 or more doses.

Precautions while using siponimod

It is very important that your doctor check your progress at regular visits to make sure siponimod is working properly. Blood and urine tests may be needed to check for any unwanted effects.

Symptoms of your MS may return and become worse after stopping treatment with siponimod. Do not stop using siponimod without checking first with your doctor.

Using siponimod while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with siponimod and for 10 days after the last dose. If you think you have become pregnant while using siponimod, tell your doctor right away.

Siponimod may increase your risk of developing infections, including a herpes infection or a serious brain infection called meningitis or progressive multifocal leukoencephalopathy. Avoid being near people who are sick or have infections while you are using siponimod. Wash your hands often. Also tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.

Check with your doctor right away if blurred vision, difficulty with reading, or any other change in vision occurs during or after treatment. Your doctor may want your eyes be checked by an ophthalmologist (eye doctor).

Siponimod may cause heart rhythm problems. Tell your doctor right away if you get dizzy or lightheaded, have a fast, slow, or irregular heartbeat, or feel like fainting.

Tell your doctor right away if you have a cough, trouble breathing, chest tightness, or any type of breathing problem with siponimod. These could be symptoms of a serious lung problem.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Tell your doctor right away if you have seizures, headache, confusion, vision problems, unusual drowsiness, tiredness, or weakness. These could be symptoms of a serious nervous system problem called posterior reversible encephalopathy syndrome (PRES).

While you are being treated with siponimod, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Do not use siponimod 1 week before and for 4 weeks after receiving a vaccine. Siponimod may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
