2 DOSAGE AND ADMINISTRATION

2.1 Dosing Information in Adults


The recommended starting dose of rizatriptan benzoate orally disintegrating 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)].
Redosing in Adults

Although the effectiveness of a second dose or subsequent doses has not been established in placebo-controlled trials, if the migraine headache returns, a second dose may be administered 2 hours after the first dose. The maximum daily dose should not exceed 30 mg in any 24-hour period. The safety of treating, on average, more than four headaches in a 30-day period has not been established.

2.2 Dosing Information in Pediatric Patients (Age 6 to 17 Years)

Dosing in pediatric patients is based on the patient’s body weight. The recommended dose of rizatriptan benzoate orally disintegrating tablets is 5 mg in patients weighing less than 40 kg (88 lb), and 10 mg in patients weighing 40 kg (88 lb) or more. The efficacy and safety of treatment with more than one dose of rizatriptan benzoate orally disintegrating tablets within 24 hours in pediatric patients 6 to 17 years of age have not been established.

2.3 Administration of Rizatriptan Benzoate Orally Disintegrating Tablets

For rizatriptan benzoate orally disintegrating tablets, administration with liquid is not necessary. Orally disintegrating tablets are packaged in a blister within a carton and patients should not remove the blister from the carton until just prior to dosing. The blister pack should then be peeled open with dry hands and the orally disintegrating tablet placed on the tongue, where it will dissolve and be swallowed with the saliva.

2.4 Dosage Adjustment for Patients on Propranolol

Adult Patients
In adult patients taking propranolol, only the 5 mg dose of rizatriptan benzoate orally disintegrating tablets is recommended, up to a maximum of 3 doses in any 24-hour period (15 mg) [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

Pediatric Patients
For pediatric patients weighing ≥40 kg (88 lb) taking propranolol, only a single 5 mg dose of rizatriptan benzoate orally disintegrating tablets is recommended (maximum dose of 5 mg in a 24-hour period). Rizatriptan benzoate orally disintegrating tablets should not be prescribed to propranolol-treated pediatric patients who weigh less than 40 kg (88 lb) [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].

5 WARNINGS AND PRECAUTIONS

5.1 Myocardial Ischemia, Myocardial Infarction, and Prinzmetal’s Angina

Rizatriptan benzoate should not be given to patients with ischemic or vasospastic coronary artery disease. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of rizatriptan benzoate. Some of these reactions occurred in patients without known coronary artery disease (CAD). 5-HT1 agonists including rizatriptan benzoate may cause coronary artery vasospasm (Prinzmetal’s Angina), even in patients without a history of CAD.Triptan-naïve patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) should have a cardiovascular evaluation prior to receiving rizatriptan benzoate. If there is evidence of CAD or coronary artery vasospasm, rizatriptan benzoate should not be administered [see Contraindications (4)]. For patients who have a negative cardiovascular evaluation, consideration should be given to administration of the first rizatriptan benzoate dose in a medically-supervised setting and performing an electrocardiogram (ECG) immediately following rizatriptan benzoate administration. Periodic cardiovascular evaluation should be considered in intermittent long-term users of rizatriptan benzoate who have cardiovascular risk factors.

5.2 Arrhythmias

Life-threatening disturbances of cardiac rhythm, including ventricular tachycardia and ventricular fibrillation leading to death, have been reported within a few hours following the administration of 5-HT1 agonists. Discontinue rizatriptan benzoate if these disturbances occur.

5.3 Chest, Throat, Neck and/or Jaw Pain/Tightness/Pressure

As with other 5-HT1 agonists, sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck and jaw commonly occur after treatment with rizatriptan benzoate and are usually non­-cardiac in origin. However, if a cardiac origin is suspected, patients should be evaluated. Patients shown to have CAD and those with Prinzmetal’s variant angina should not receive 5-HT1 agonists.
