How to Take Gilenya
Gilenya (fingolimod) treats relapsing multiple sclerosis in adults and children 10 years and older. Take one 0.5 mg capsule daily, with or without food, at the same time each day. Swallow whole; do not open, crush, or chew. First dose requires 6-hour monitoring in a doctor's office for heart rate effects [1][2].
Starting Treatment: First-Dose Observation
Before your first dose, your doctor checks heart rate, blood pressure, and EKG if needed. Stay at the medical facility for 6 hours post-dose. They'll monitor heart rate every hour. You cannot leave until heart rate stabilizes (at least 2 hours above 60 bpm after 6 hours, or longer if issues arise). Carry a monitoring card for 24 hours after [1][2].
What If I Miss a Dose?
Take as soon as remembered on the same day. Skip if almost time for next dose—never double up. Restart first-dose monitoring if you miss one or more days [1][2].
Dosage for Children
Same 0.5 mg daily capsule for kids 10+ weighing over 40 kg (88 lbs). No adjustment for body weight alone; doctor assesses overall [1][2].
Special Instructions and Precautions
- Continue other MS treatments unless doctor says otherwise.
- Women: Use birth control; Gilenya harms fetuses. Stop 2 months before planning pregnancy.
- Vaccinations: Avoid live vaccines during treatment and 2 months after.
- Store at room temperature, away from moisture [1][2].
Common Side Effects Patients Report
Headache, back pain, high blood pressure, diarrhea, cough, flu-like symptoms. Serious risks include slow heartbeat (especially first dose), infections, swelling (macular edema), breathing issues, skin cancer, and posterior reversible encephalopathy syndrome. Report vision changes, fever, or swelling immediately [1][2].
Interactions and Who Should Avoid It
Avoid with heart conditions, recent heart attack/stroke, some heart rhythm drugs (Class Ia/Ib or III), or QT-prolonging meds. Inform doctor of infections, immune issues, diabetes, or seizures. Check liver function before starting [1][2].
How Long Until It Works and When to Stop
Effects start within 1-2 months. Do not stop without doctor guidance—symptoms may worsen. Washout period needed before switching MS drugs (e.g., 1-2 months for some) [1][2].
