Siponimod - oral
Siponimod - oral
This medication is used to treat a certain type of multiple sclerosis (relapsing multiple sclerosis-MS). Siponimod is not a cure for MS but it is thought to help by preventing immune system cells (lymphocytes) from attacking the nerves in your brain and spinal cord. It helps decrease the number of episodes of disease worsening (relapses) and may prevent or delay disability.
Read the Medication Guide provided by your pharmacist before you start taking siponimod and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Before starting siponimod, your doctor will do medical/lab tests (such as complete blood count, liver function tests, blood pressure, EKG, pulse, eye/skin exam) to monitor for side effects. Take this medication by mouth with or without food as directed by your doctor, usually once a day. Swallow the tablets whole. Do not split, crush, or chew the tablets.
To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.
Some people may need to be monitored for at least 6 hours after the first dose to make sure their heartbeat does not go too slow. A very slow heartbeat increases the risk for a serious heart rhythm problem. Tell your doctor if you have a slow/irregular heartbeat or other heart problems (such as heart failure, history of heart attack).
Do not stop taking this medication without consulting your doctor. Your condition may become worse when this drug is stopped. Tell your doctor right away if your MS symptoms are much worse after stopping siponimod.
The dosage is based on your medical condition and response to treatment. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Tell your doctor if your condition gets worse.
Headache or swelling of arms/legs may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.
This medication may rarely cause serious liver disease. Tell your doctor right away if you have any symptoms of liver disease, such as:
This medication can weaken your immune system/increase the risk of infection while you are taking it and for 3 to 4 weeks after your last dose. You may be more likely to get a serious (possibly fatal) infection (such as bronchitis, herpes). Tell your doctor right away if you develop any signs of an infection such as sore throat/cough that doesn't go away, difficulty breathing, fever/chills, cold/flu symptoms, sores, or blisters. Do not start siponimod if you already have an infection.
This medication may increase your risk of getting a rare but very serious (possibly fatal) brain infection (progressive multifocal leukoencephalopathy-PML). Symptoms of PML can seem like a worsening MS attack. Get medical help right away if you have any new or worsening symptoms that have lasted for several days, such as clumsiness or problems with strength, balance, speech, eyesight, or thinking.
Siponimod may rarely increase your risk of skin cancer. Tell your doctor right away if you notice any unusual skin changes (such as change in appearance/size of moles).
