Understanding this RxNorm record
RxNorm identifiers distinguish ingredients, specific strengths, dose forms, and branded products. They help connect equivalent terminology across data sources; an RxNorm entry does not by itself establish that a product is currently marketed, approved for a particular use, or appropriate for an individual.
Clinical-trial associations reflect registry-reported intervention names and verified mappings where available. A medication listed in a trial may be investigational for that condition. Consult the original study record and official prescribing information for indications and safety details.

Dihydroergotamine
Dihydroergotamine (DHE), sold under the brand names D.H.E. 45 and Migranal among others, is an ergot alkaloid used to treat migraines. It is a derivative of ergotamine. It is administered as a nasal spray or injection and has an efficacy similar to that of sumatriptan. Nausea is a common side effect. It has similar actions to the triptans, acting as an agonist to the serotonin receptors and causing vasoconstriction of the intracranial blood vessels, but also interacts centrally with dopamine and adrenergic receptors. It can be used to treat acute intractable headache or withdrawal from analgesics.
