Fingolimod Dosage

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

Fingolimod may cause the heartbeat to slow in adults and children, especially during the first 6 hours after you take your first dose, and after the first dose when the dose is increased in children. You will receive an electrocardiogram (ECG; a test that records the electrical activity of the heart) before you take your first dose and again 6 hours after you take the dose. You will take your first dose of fingolimod in your doctor’s office or another medical facility. You will need to stay at the medical facility for at least 6 hours after you take the medication so that you can be monitored. You may need to stay at the medical facility for longer than 6 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 6 hours. You may also need to stay at a medical facility for at least 6 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, especially during the first 24 hours after you take your first dose.

Fingolimod may help control multiple sclerosis but will not cure it. Do not stop taking fingolimod without talking to your doctor. If you do not take fingolimod for 1 day or longer during the first 2 weeks of treatment, for 1 week or longer in the third and fourth weeks of treatment, or for 2 weeks or longer after the first month of treatment, talk to your doctor before you start taking it again. You may experience slowed heartbeat when you start taking fingolimod again, so you will need to restart the medication in your doctor’s office.


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