1 INDICATIONS AND USAGE Naratriptan tablets are indicated for the acute treatment of migraine with or without aura in adults.

Naratriptan tablets are not indicated for the prevention of migraine attacks. Safety and effectiveness of naratriptan tablets have not been established for cluster headache. Naratriptan Tablets are serotonin (5-HT 1B/1D ) receptor agonists (triptan) indicated for the acute treatment of migraine with or without aura in adults.

Dosage & Administration
2 DOSAGE AND ADMINISTRATION Recommended dose: 1 mg or 2.5 mg. ( 2.1 ) May repeat dose after 4 hours if needed; not to exceed 5 mg in any 24- hour period. ( 2.1 ) Mild or moderate renal or hepatic impairment: recommended starting dose is 1 mg not to exceed 2.5 mg in any 24-hour period. ( 2.2 , 2.3 ) 2.1 Dosing Information The recommended dose of naratriptan tablets is 1 mg or 2.5 mg. If the migraine returns or if the patient has only partial response, the dose may be repeated once after 4 hours, for a maximum dose of 5 mg in a 24-hour period. The safety of treating an average of more than 4 migraine attacks in a 30-day period has not been established. 2.2 Dosage Adjustment in Patients With Renal Impairment Naratriptan tablets are contraindicated in patients with severe renal impairment (creatinine clearance: <15 mL/min) because of decreased clearance of the drug [see Contraindications (4) , Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ]. In patients with mild to moderate renal impairment, the maximum daily dose should not exceed 2.5 mg over a 24-hour period and a 1-mg starting dose is recommended [see Use in Specific Populations (8.6) , Clinical Pharmacology (12.3) ]. 2.3 Dosage Adjustment in Patients With Hepatic Impairment Naratriptan tablets are contraindicated in patients with severe hepatic impairment (Child-Pugh Grade C) because of decreased clearance [see Contraindications (4) , Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ]. In patients with mild or moderate hepatic impairment (Child-Pugh Grade A or B), the maximum daily dose should not exceed 2.5 mg over a 24-hour period and a 1-mg starting dose is recommended [ see Use in Specific Populations (8.7) , Clinical Pharmacology (12.3) ].
Adverse Reactions
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 [s ee 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) ] Hypersensitivity reactions [see Contraindications (4) , Warnings and Precautions (5.9) ] Most common adverse reactions (≥2% and >placebo) were paresthesias, nausea, dizziness, drowsiness, malaise/fatigue, and throat/neck symptoms. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Avet Pharmaceuticals Inc. at 1-866-901-DRUG (3784) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. In a long-term open-label trial where patients were allowed to treat multiple migraine attacks for up to 1 year, 15 patients (3.6%) discontinued treatment due to adverse reactions. In controlled clinical trials, the most common adverse reactions were paresthesias, dizziness, drowsiness, malaise/fatigue, and throat/neck symptoms, which occurred at a rate of 2% and at least 2 times placebo rate. Table 1 lists the adverse reactions that occurred in 5 placebo-controlled clinical trials of approximately 1,752 exposures to placebo and naratriptan tablets in adult patients with migraine. Only reactions that occurred at a frequency of 2% or more in groups treated with naratriptan tablets 2.5 mg and that occurred at a frequency greater than the placebo group in the 5 pooled trials are included in Table 1. Table 1. Adverse Reactions Reported by at Least 2% of Patients Treated With Naratriptan Tablets and at a Frequency Greater Than Placebo Adverse Reaction Percent of Patients Reporting Naratriptan Tablets 1 mg (n = 627) Naratriptan Tablets 2.5 mg (n = 627) Placebo (n = 498) Atypical sensation 2 4 1 Paresthesias (all types) 1 2 <1 Gastrointestinal 6 7 5 Nausea 4 5 4 Neurological 4 7 3 Dizziness 1 2 1 Drowsiness 1 2 <1 Malaise/fatigue 2 2 1 Pain and pressure sensation 2 4 2 Throat/neck symptoms 1 2 1 The incidence of adverse reactions in controlled clinical trials was not affected by age or weight of the patients, duration of headache prior to treatment, presence of aura, use of prophylactic medications, or tobacco use. There were insufficient data to assess the impact of race on the incidence of adverse reactions.
Information for Patients
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Risk of Myocardial Ischemia and/or Infarction, Prinzmetal's Angina, Other Vasospasm-Related Events, Arrhythmias, and Cerebrovascular Events: Inform patients that naratriptan tablets may cause serious cardiovascular side effects such as myocardial infarction or stroke. Although serious cardiovascular events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, irregular heartbeat, significant rise in blood pressure, weakness, and slurring of speech and should ask for medical advice if any indicative sign or symptoms are observed. Apprise patients of the importance of this follow-up [see Warnings and Precautions ( 5.1 , 5.2 , 5.4 , 5.5 , 5.8 )]. Anaphylactic Reactions: Inform patients that anaphylactic reactions have occurred in patients receiving naratriptan tablets. Such reactions can be life threatening or fatal. In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens [see Contraindications (4) , Warnings and Precautions (5.9) ]. Concomitant Use With Other Triptans or Ergot Medications: Inform patients that use of naratriptan tablets within 24 hours of another triptan or an ergot-type medication (including dihydroergotamine or methysergide) is contraindicated [see Contraindications (4) , Drug Interactions ( 7.1 , 7.2 )]. Serotonin Syndrome: Caution patients about the risk of serotonin syndrome with the use of naratriptan tablets or other triptans, particularly during combined use with SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.7) , Drug Interactions (7.3) ]. Medication Overuse Headache: Inform patients that use of acute migraine drugs for 10 or more days per month may lead to an exacerbation of headache and encourage patients to record headache frequency and drug use (e.g., by keeping a headache diary) [see Warnings and Precautions (5.6) ]. Pregnancy: Advise patients to notify their healthcare provider if they become pregnant during treatment or intend to become pregnant [see Use in Specific Populations (8.1) ]. Lactation: Advise patients to notify their healthcare provider if they are breastfeeding or plan to breastfeed [see Use in Specific Populations (8.2) ].
