Not for administration to patients who have risk factors for coronary artery disease (CAD), including hypertension, obesity, hypercholesterolemia, diabetes, menopause, strong family history of CAD, male >40 years of age or is a smoker unless patient undergoes adequate cardiac evaluation; patients suspected of having CAD, should have CAD ruled out before considering use of drug; if evaluation satisfactory, first dose should be administered in the healthcare provider’s office; perform periodic evaluation of cardiovascular status in all patients
Drug interaction overview
- Potentially life-threatening serotonin syndrome may occur, particularly during combined use with SSRIs, SNRIs, TCAs, or MAOIs
- Rizatriptan use is contraindicated with concurrent administration of or recent discontinuation (ie, within 2 weeks) of MAOIs
- Propranolol increases rizatriptan AUC by 70%; decrease rizatriptan dose if coadministered adjustment needed (see Dosage Modifications)
- Ergot-containing drugs may cause prolonged vasospastic reactions; because these effects may be additive if coadministered, use of ergotamine-containing medications and rizatriptan are contraindicated within 24 hr
- Similarly, use of other 5-HT1 agonists within 24 hr of rizatriptan is contraindicated owning to additive vasospasm reactions
Pregnancy & Lactation
Pregnancy
Available data in pregnant women are not sufficient to draw conclusions about drug-associated risk for major birth defects and miscarriage
The Pregnancy Registry for rizatriptan did not identify any pattern of congenital anomalies or other adverse birth outcomes over the period of 1998-2018; however, the lack of identification of any pattern should be viewed with caution, as the number of prospective reports with outcome information was low and did not provide sufficient power to detect an increased risk of individual birth defects associated with the use
Additionally, there was significant loss to follow-up in the prospective pregnancy reports, further complicating this assessment of an association between rizatriptan and any pattern of congenital anomalies or other adverse birth outcomes
Animal data
- 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
Clinical considerations
- In women with migraine, there is an increased risk of adverse perinatal outcomes in the mother, including pre-eclampsia and gestational hypertension
Lactation
Data are not available on the presence of rizatriptan or any active metabolites in human milk, or on the effects of rizatriptan on the breastfed infant, or on milk production
Rizatriptan was excreted in rat milk, with levels in milk ~6 times those in maternal plasma
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

RIZATRIPTAN TABLET - ORAL
(RYE-za-TRIP-tan)
COMMON BRAND NAME(S): Maxalt
USES: Rizatriptan is used to treat migraines. It helps to relieve headache, pain, and other migraine symptoms (including nausea, vomiting, sensitivity to light/sound). Prompt treatment helps you return to your normal routine and may decrease your need for other pain medications. Rizatriptan belongs to a class of drugs known as triptans. It affects a certain natural substance (serotonin) that causes narrowing of blood vessels in the brain. It may also relieve pain by affecting certain nerves in the brain.Rizatriptan does not prevent future migraines or lessen how often you get migraine attacks.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking rizatriptan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth as directed by your doctor, at the first sign of a migraine. It may be taken with or without food, but may work faster when it is taken on an empty stomach. The dosage is based on your medical condition, age, response to treatment, and other drugs you may be taking. For children, the dosage is also based on weight.
