This medication is used to treat a certain type of multiple sclerosis (relapsing multiple sclerosis-MS). It 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 worsening and may prevent or delay disability.
Before starting fingolimod, your doctor will do medical/laboratory tests (such as complete blood count, blood pressure, EKG, pulse, eye exam) to monitor for side effects. Take this medication by mouth with or without food as directed by your doctor, usually once a day. You will be monitored for at least 6 hours after the first dose to make sure your heartbeat does not go too slow. A very slow heartbeat increases the risk for a serious heart rhythm problem (QT prolongation in the EKG). Tell your doctor if you have low levels of magnesium/potassium in the blood, personal or family history of QT prolongation in the EKG, family history of sudden cardiac death, or heart failure. Also tell your doctor if you are taking other drugs that can slow down your heartbeat or affect heart rhythm (such as causing QT prolongation in the EKG). See also Drug Interactions section.
If you temporarily stop taking fingolimod after starting treatment, you may need to be monitored again for at least 6 hours after you restart this medication. Ask your doctor for details.
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.
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 does not improve or if it worsens.
Remember that your doctor has prescribed this medication because he or she 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 can weaken your immune system/increase the risk of infection while you are taking it and for 2 months after your last dose. You may be more likely to get a serious infection (such as bronchitis, pneumonia, herpes). Tell your doctor right away if you develop any signs of an infection such as persistent cough/sore throat, difficulty breathing, fever/chills, cold/flu symptoms, sores, or blisters. Do not start fingolimod if you already have an infection.
Fingolimod may increase the risk of a rare (possibly fatal) brain infection (progressive multifocal leukoencephalopathy-PML). This may sometimes occur even after treatment has stopped. Symptoms of PML can seem like a worsening MS attack. Tell your doctor 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.
Get medical help right away if you have any very serious side effects, including: shortness of breath, chest pain, severe dizziness/fainting, slow/irregular/pounding/fast heartbeat, unusual tiredness/weakness, eye pain/sensitivity to light, vision changes (such as blurred vision, blind spot/shadows in the center of your vision, color changes), seizure, sudden/severe headache.
This medication may rarely cause serious liver problems. Tell your doctor right away if you experience: nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
