1 INDICATIONS AND USAGE Sumatriptan Nasal Spray is indicated for the acute treatment of migraine with or without aura in adults. Limitations of Use: • Use only if a clear diagnosis of migraine headache has been established. If a patient has no response to the first migraine attack treated with Sumatriptan Nasal Spray, reconsider the diagnosis of migraine before Sumatriptan Nasal Spray is administered to treat any subsequent attacks. • Sumatriptan is not indicated for the prevention of migraine attacks. • Safety and effectiveness of Sumatriptan Nasal Spray have not been established for cluster headache. Sumatriptan is a serotonin (5-HT 1B/1D ) receptor agonist (triptan) indicated for acute treatment of migraine with or without aura in adults. Limitations of Use: • Use only if a clear diagnosis of migraine headache has been established. (1) • Not indicated for the prophylactic therapy of migraine attacks. (1) • Not indicated for the treatment of cluster headache. (1)

2 DOSAGE AND ADMINISTRATION The recommended adult dose of Sumatriptan Nasal Spray for the acute treatment of migraine is 5 mg, 10 mg, or 20 mg. The 20-mg dose may provide a greater effect than the 5-mg and 10-mg doses, but may have a greater risk of adverse reactions [see Clinical Studies (14) ] . The 5-mg and 20-mg doses are given as a single spray in 1 nostril. The 10-mg dose may be achieved by the administration of a single 5-mg dose in each nostril. If the migraine has not resolved by 2 hours after taking Sumatriptan Nasal Spray, or returns after a transient improvement, 1 additional dose may be administered at least 2 hours after the first dose. The maximum daily dose is 40 mg in a 24-hour period. The safety of treating an average of more than 4 headaches in a 30-day period has not been established. • Single dose of 5 mg, 10 mg, or 20 mg of nasal spray. (2) • A second dose should only be considered if some response to the first dose was observed. Separate doses by at least 2 hours. (2) • Maximum dose in a 24-hour period: 40 mg. (2)

4 CONTRAINDICATIONS Sumatriptan Nasal Spray is contraindicated in patients with: • Ischemic coronary artery disease (CAD) (angina pectoris, history of myocardial infarction, or documented silent ischemia) or coronary artery vasospasm, including Prinzmetal’s angina [see Warnings and Precautions (5.1) ] • Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders [see Warnings and Precautions (5.2) ] • History of stroke, transient ischemic attack (TIA), or history of hemiplegic or basilar migraine because these patients are at a higher risk of stroke [see Warnings and Precautions (5.4) ] • Peripheral vascular disease [see Warnings and Precautions (5.5) ] • Ischemic bowel disease [see Warnings and Precautions (5.5) ] • Uncontrolled hypertension [see Warnings and Precautions (5.8) ] • Recent use (i.e., within 24 hours) of ergotamine-containing medication, ergot-type medication (such as dihydroergotamine or methysergide), or another 5-hydroxytryptamine 1 (5-HT 1 ) agonist [see Drug Interactions ( 7.1 , 7.3 )] • Concurrent administration of a monoamine oxidase (MAO)-A inhibitor or recent (within 2 weeks) use of an MAO-A inhibitor [see Drug Interactions (7.2) , Clinical Pharmacology (12.3) ] • Hypersensitivity to sumatriptan (angioedema and anaphylaxis seen) [see Warnings and Precautions (5.10) ] • Severe hepatic impairment [see Clinical Pharmacology (12.3) ] • History of coronary artery disease or coronary artery vasospasm (4) • Wolff-Parkinson-White syndrome or other cardiac accessory conduction pathway disorders (4) • History of stroke, transient ischemic attack, or hemiplegic or basilar migraine (4) • Peripheral vascular disease (4) • Ischemic bowel disease (4) • Uncontrolled hypertension (4) • Recent (within 24 hours) use of another 5-HT 1 agonist (e.g., another triptan) or of an ergotamine-containing medication. (4) • Concurrent or recent (past 2 weeks) use of monoamine oxidase-A inhibitor. (4) • Hypersensitivity to sumatriptan (angioedema and anaphylaxis seen). (4) • Severe hepatic impairment (4)

6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail in other sections of the prescribing information: • Myocardial ischemia, myocardial infarction, and Prinzmetal’s angina [see Warnings and Precautions (5.1) ] • Arrhythmias [see Warnings and Precautions (5.2) ] • Chest, throat, neck, and/or jaw pain/tightness/pressure [see Warnings and Precautions (5.3) ] • Cerebrovascular events [see Warnings and Precautions (5.4) ] • Other vasospasm reactions [see Warnings and Precautions (5.5) ] • Medication overuse headache [see Warnings and Precautions (5.6) ] • Serotonin syndrome [see Warnings and Precautions (5.7) ] • Increase in blood pressure [see Warnings and Precautions (5.8) ] • Local irritation [see Warnings and Precautions (5.9) ] • Hypersensitivity reactions [see Contraindications (4) , Warnings and Precautions (5.10) ] • Seizures [see Warnings and Precautions (5.11) ] Most common adverse reactions (≥1% and >placebo) were burning sensation, disorder/discomfort of nasal cavity/sinuses, throat discomfort, nausea and/or vomiting, bad/unusual taste, and dizziness/vertigo.

Table 1 lists adverse reactions that occurred in worldwide placebo-controlled clinical trials in 3,419 patients with migraine. Only treatment-emergent adverse reactions that occurred at a frequency of 1% or more in the group treated with sumatriptan nasal spray 20 mg and that occurred at a frequency greater than the placebo group are included in Table 1. Table 1. Adverse Reactions Reported by at Least 1% of Patients and at a Greater Frequency than Placebo in Controlled Migraine Clinical Trials Adverse Reaction Percent of Patients Reporting Sumatriptan Nasal Spray 5 mg (n = 496) Sumatriptan Nasal Spray 10 mg (n = 1,007) Sumatriptan Nasal Spray 20 mg (n = 1,212) Placebo (n=704) Atypical sensations Burning sensation 0.4 0.6 1.4 0.1 Ear, nose, and throat Disorder/discomfort of nasal cavity/sinuses 2.8 2.5 3.8 2.4 Throat discomfort 0.8 1.8 2.4 0.9 Gastrointestinal Nausea and/or vomiting 12.2 11.0 13.5 11.3 Neurological Bad/unusual taste 13.5 19.3 24.5 1.7 Dizziness/vertigo 1.0 1.7 1.4 0.9 The incidence of adverse reactions in controlled clinical trials was not affected by gender, weight, or age of the patients; use of prophylactic medications; or presence of aura. There were insufficient data to assess the impact of race on the incidence of adverse reactions. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of sumatriptan tablets, sumatriptan nasal spray, and sumatriptan injection. 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. These reactions have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to sumatriptan or a combination of these factors. Cardiovascular Hypotension, palpitations. Neurological Dystonia, tremor.
