Eletriptanside effects

The following adverse reactions are described elsewhere in other sections of the prescribing information:

Myocardial ischemia and myocardial infarction, and Prinzmetal’s angina

Arrhythmias

Chest, throat, neck, and/or jaw pain/tightness/pressure

Cerebrovascular events

Other vasospasm reactions

Medication overuse headache

Serotonin syndrome

Increase in blood pressure

Hypersensitivity reactions Most common adverse reactions (≥ 5% and > placebo) were asthenia, nausea, dizziness, and somnolence. These reactions appear to be dose-related.

6.1 Clinical

Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Among 4,597 patients who treated the first migraine headache with eletriptan hydrobromide tablets in short-term placebo-controlled trials, the most common adverse reactions reported with treatment with eletriptan hydrobromide tablets were asthenia, nausea, dizziness, and somnolence. These reactions appear to be dose-related. In long-term open-label studies where patients were allowed to treat multiple migraine attacks for up to 1 year, 128 (8.3%) out of 1,544 patients discontinued treatment due to adverse reactions. Table 1 lists adverse reactions that occurred in the subset of 5,125 migraineurs who received eletriptan doses of 20 mg, 40 mg and 80 mg or placebo in worldwide placebo-controlled clinical trials. Only adverse reactions that were more frequent in an eletriptan hydrobromide tablet treatment group compared to the placebo group with an incidence greater than or equal to 2% are included in Table 1.

The incidence of adverse reactions in controlled clinical trials was not affected by gender, age, or race of the patients. Adverse reaction frequencies were also unchanged by concomitant use of drugs commonly taken for migraine prophylaxis (e.g., SSRIs, beta blockers, calcium channel blockers, tricyclic antidepressants), estrogen replacement therapy or oral contraceptives.

6.2 Postmarketing

Experience The following adverse reaction(s) have been identified during post approval use of eletriptan hydrobromide tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Neurological: seizure Digestive: vomiting
