Uses
1 INDICATIONS & USAGE Ri zatriptan benzoate tablets are indicated for the acute treatment of migraine with or without aura in adults and in pediatric patients 6 to 17 years old. Limitations of Use • Rizatriptan benzoate tablets should only be used where a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with rizatriptan benzoate tablets, the diagnosis of migraine should be reconsidered before rizatriptan benzoate tablets are administered to treat any subsequent attacks. • Rizatriptan benzoate tablets are not indicated for use in the management of hemiplegic or basilar migraine [see Contraindications (4) ]. • Rizatriptan benzoate tablets are not indicated for the prevention of migraine attacks.
Dosage
2 DOSAGE & ADMINISTRATION Adults: 5 mg or 10 mg single dose; separate repeat doses by at least two hours; maximum dose in a 24-hour period: 30 mg (2.1) Pediatric patients 6 to 17 years: 5 mg single dose in patients less than 40 kg (88 lb); 10 mg single dose in patients 40 kg (88 lb) or more ( 2.2 ) Adjust dose if co-administered with propranolol ( 2.4 ) 2.1 Dosing Information in Adults The recommended starting dose of rizatriptan benzoate tablets is either 5 mg or 10 mg for the acute treatment of migraines in adults. The 10-mg dose may provide a greater effect than the 5-mg dose, but may have a greater risk of adverse reactions [see Clinical Studies (14.1) ].
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail in other sections of the labeling: • 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 )].
Interactions
7 DRUG INTERACTIONS 7.1 Propranolol The dose of rizatriptan benzoate should be adjusted in propranolol-treated patients, as propranolol has been shown to increase the plasma AUC of rizatriptan by 70% [see Dosage and Administration ( 2.4 ) and Clinical Pharmacology ( 12.3 )] . 7.2 Ergot-Containing Drugs Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and rizatriptan benzoate within 24 hours is contraindicated [see Contraindications ( 4 )] .
Warnings
5 WARNINGS AND PRECAUTIONS • Myocardial ischemia, myocardial infarction, and Prinzmetal's angina: Perform cardiac evaluation in patients with multiple cardiovascular risk factors ( 5.1 ) • Arrhythmias: Discontinue dosing if occurs ( 5.2 ) • Chest/throat/neck/jaw pain, tightness, pressure, or heaviness; Generally not associated with myocardial ischemia; Evaluate patients at high risk ( 5.3 ) • Cerebral hemorrhage, subarachnoid hemorrhage, and stroke: Discontinue dosing if occurs ( 5.4 ) • Gastrointestinal ischemic events, peripheral vasospastic reactions: Discontinue dosing if occurs ( 5.5 ) • Medication overuse headache: Detoxification may be necessary ( 5.6 ) • Serotonin syndrome: Discontinue dosing if occurs ( 5.7 ) 5.1 Myocardial Ischemia, Myocardial Infarction, and Prinzmetal's Angina... 4 CONTRAINDICATIONS Rizatriptan benzoate tablets are contraindicated in patients with: • Ischemic coronary artery disease (angina pectoris, history of myocardial infarction, or documented silent ischemia), or other significant underlying cardiovascular disease [see Warnings and Precautions ( 5.1 )]. • Coronary artery vasospasm including Prinzmetal's angina [see Warnings and Precautions ( 5.1 )].
Pregnancy
8.1 Pregnancy Risk Summary Available human data on the use of rizatriptan benzoate in pregnant women are not sufficient to draw conclusions about drug-associated risk for major birth defects and miscarriage. In animal studies, developmental toxicity was observed following oral administration of rizatriptan during pregnancy (decreased fetal body weight in rats) or throughout pregnancy and lactation (increased mortality, decreased body weight, and neurobehavioral impairment in rat offspring) at maternal plasma exposures greater than that expected at therapeutic doses in humans [see Animal Data]....
