Gilenya (fingolimod) is a sphingosine 1-phosphate receptor modulator used to treat patients with relapsing forms of multiple sclerosis (MS) to reduce the frequency of exacerbations and to delay physical disability. Common side effects of Gilenya are headache, tired feeling, influenza, stuffy nose, sinus pain, 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.

(Adverse Reactions)


The following serious adverse reactions are described elsewhere in labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical trials (Studies 1, 2, and 3), a total of 1212 patients with relapsing forms of multiple sclerosis received GILENYA 0.5 mg. This included 783 patients who received GILENYA 0.5 mg in the 2-year placebo-controlled trials (Studies 1 and 3) and 429 patients who received GILENYA 0.5 mg in the 1 year active-controlled trial (Study 2). The overall exposure in the controlled trials was equivalent to 1716 person-years. Approximately 1000 patients received at least 2 years of treatment with GILENYA 0.5 mg. In all clinical studies, including uncontrolled extension studies, the exposure to GILENYA 0.5 mg was approximately 4119 person-years.

In placebo-controlled trials, the most frequent adverse reactions (incidence ≥ 10% and > placebo) for GILENYA 0.5 mg were headache, liver transaminase elevation, diarrhea, cough, influenza, sinusitis, back pain, abdominal pain, and pain in extremity. Adverse events that led to treatment discontinuation and occurred in more than 1% of patients taking GILENYA 0.5 mg were serum transaminase elevations (4.7% compared to 1% on placebo) and basal cell carcinoma (1% compared to 0.5% on placebo).

Table 1 lists adverse reactions that occurred in ≥ 1% of GILENYA-treated patients and ≥ 1% higher rate than for placebo.

Table 1 : Adverse Reactions Reported in Studies 1 and 3 (Occurring in ≥ 1% of Patients and Reported for GILENYA 0.5 mg at ≥ 1% Higher Rate than for Placebo)

Adverse reactions of dizziness, pneumonia, eczema and pruritus were also reported in Studies 1 and 3 but did not meet the reporting rate criteria for inclusion in Table 1 (difference was less than 1%).

Adverse reactions with GILENYA 0.5 mg in Study 2, the 1-year active-controlled (versus interferon beta-1a) study were generally similar to those in Studies 1 and 3.

Vascular Events

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 in the postmarketing setting although a causal relationship has not been established.


Cases of lymphoma, including both T-cell and B-cell types and CNS lymphoma, have occurred in patients receiving GILENYA. The reporting rate of non-Hodgkin lymphoma with GILENYA is greater than that expected in the general population adjusted by age, gender, and region. The relationship of lymphoma to GILENYA remains uncertain.
