Gilenya (fingolimod) is indicated for the treatment of patients with relapsing forms of multiple sclerosis (MS) to reduce the frequency of exacerbations and to delay physical disability. Most common side effects with the use of Gilenya are headache, influenza, diarrhea, back pain, liver transaminase elevations, and cough.
The recommended dose for Gilenya is 0.5 mg orally once daily, with or without food. Gilenya may interact with beta-blockers, calcium channel blockers, citalopram, chlorpromazine, digoxin, erythromycin, haloperidol, ketoconazole, medications to control the immune system, medications for cancer, heart problems, or high blood pressure, and methadone. Tell your doctor all medications and supplements you use. Gilenya may cause fetal harm. It takes approximately 2 months for Gilenya to be eliminated from the body. Women should avoid pregnancy during treatment with Gilenya and for 2 months after treatment. It is not known if Gilenya passes into breast milk. Women and their doctors should decide whether to take Gilenya or breastfeed. Women should not do both.
Our Gilenya (fingolimod) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Gilenya FDA Prescribing Information: Side Effects
The following serious adverse reactions are described elsewhere in labeling:
- Bradyarrhythmia and Atrioventricular Blocks [see WARNINGS AND PRECAUTIONS]
- Infections [see WARNINGS AND PRECAUTIONS]
- Macular Edema [see WARNINGS AND PRECAUTIONS]
- Posterior Reversible Encephalopathy Syndrome [see WARNINGS AND PRECAUTIONS]
- Respiratory Effects [see WARNINGS AND PRECAUTIONS]
- Liver Injury [see WARNINGS AND PRECAUTIONS]
The most frequent adverse reactions (incidence ≥ 10% and > placebo) for GILENYA 0.5 mg were headache, influenza, diarrhea, back pain, liver enzyme elevations, and cough. The only adverse event leading to treatment interruption reported at an incidence > 1% for GILENYA 0.5 mg was serum transaminase elevations (3.8%).
Clinical Trials Experience
A total of 1703 patients on GILENYA (0.5 or 1.25 mg once daily) constituted the safety population in the 2 controlled studies in patients with relapsing-remitting MS (RRMS) [see Clinical Studies].
Study 1 was a 2-year placebo-controlled clinical study in 1272 MS patients treated with GILENYA 0.5 mg (N=425), GILENYA 1.25 mg (N=429), or placebo (N=418).
Table 1 : Adverse Reactions in Study 1 (Occurring in
≥ 1% of Patients and Reported for GILENYA 0.5 mg at ≥ 1% Higher Rate
than for Placebo)
|Primary System Organ Class
|GILENYA 0.5 mg
|Influenza viral infections||13||10|
|Herpes viral infections||9||8|
|Nervous system disorders|
|General disorders and administration site conditions|
|Musculoskeletal and connective tissue disorders|
|Skin and subcutaneous tissue disorders|
|Blood triglycerides increased||3||1|
|Respiratory, thoracic, and mediastinal disorders|
|Blood and lymphatic system disorders|
Adverse reactions in Study 2, a 1-year active-controlled (versus interferon beta-1a, n=431) study including 849 patients with MS treated with fingolimod, were generally similar to those in Study 1.
Vascular events, including ischemic and hemorrhagic strokes, and peripheral arterial occlusive disease were reported in premarketing clinical trials in patients who received GILENYA doses (1.25-5 mg) higher than recommended for use in MS. Similar events have been reported with GILENYA 0.5 mg in the postmarketing setting although a causal relationship has not been established.
Cases of lymphoma (cutaneous T-cell lymphoproliferative disorders or diffuse B-cell lymphoma) were reported in premarketing clinical trials in MS patients receiving GILENYA at, or above, the recommended dose of 0.5 mg. Based on the small number of cases and short duration of exposure, the relationship to GILENYA remains uncertain.
