Important Safety Information
As with other 5-HT1 agonists, it is recommended that RELPAX not be given to patients with known or suspected ischemic heart disease, coronary artery disease, peripheral vascular disease, uncontrolled hypertension, severe hepatic impairment, history of cerebrovascular accident or transient ischemic attack.
RELPAX should not be administered to patients with hemiplegic or basilar migraine.
RELPAX should not be used within 24 hours of treatment with other 5-HT1 agonists, ergot-type medication, or in patients with known hypersensitivity to eletriptan or any of its inactive ingredients.
The maximum recommended single dose of RELPAX is 40 mg. The maximum daily dose should not exceed 80 mg.
RELPAX is metabolized by the CYP3A4 enzyme; RELPAX does not inhibit or induce CYP3A4. RELPAX should not be used within at least 72 hours of treatment with the following potent CYP3A4 inhibitors: ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir, and nelfinavir.
Potentially life-threatening serotonin syndrome may occur with triptans, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin and norepinephrine reuptake inhibitors (SNRIs).
RELPAX should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The most common adverse events reported with RELPAX 40 mg compared with placebo were dizziness (6% vs 3%), somnolence (6% vs 4%), asthenia (5% vs 3%), and nausea (5% vs 5%).
RELPAX is indicated for the acute treatment of migraine with or without aura in adults.
