The usual dose of rizatriptan for the treatment of a migraine headache once it has started is 5 mg or 10 mg. Rizatriptan is not used to prevent migraines; it should be taken only during a migraine headache. A few of the factors that can affect rizatriptan dosing include your response to rizatriptan, other drugs you may be currently taking, and other medical conditions you may have. You should not take more than 30 mg of rizatriptan tablets in a 24-hour period.
An Overview of Rizatriptan DosingThe dose of rizatriptan benzoate (Maxalt®) your healthcare provider prescribes will vary depending on a number of factors, including:
- Your weight (for children)
- Your response to rizatriptan
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
Rizatriptan Dosing for Migraine Headaches in AdultsRizatriptan is meant to be taken only during a migraine. The usual dosage of rizatriptan for migraine headaches is rizatriptan 5 mg or 10 mg. In general, the higher dose is more effective, but has more side effects. For people taking propranolol (Inderal®, Inderal LA®, InnoPran XL®), the rizatriptan dose should not be more than 5 mg.
A second dose may be given if needed (and if your healthcare provider approves) two hours after the first dose. Take no more than 30 mg per 24 hours (or 15 mg per 24 hours if you are taking propranolol).
For children and teens (6 through 17 years of age), the usual dosage of rizatriptan for migraine headaches is based on weight. For those weighing 88 pounds or less, the recommended dose is rizatriptan 5 mg. For those weighing 88 pounds or more, the recommended dosage is rizatriptan 10 mg.
The safety and effectiveness of taking a second dose if the first dose does not work adequately has not been studied in this age group.
