How TRUDHESA Works

Dihydroergotamine, the active ingredient in TRUDHESA, works by binding with high affinity to 5-HT 1Dα and 5-HT 1Dβ receptors. The medication functions as an agonist, which means it activates these specific serotonin receptors. This agonist activity at the 5-HT 1D receptors is the primary mechanism responsible for the drug's therapeutic effect in treating migraines.

TRUDHESA Boxed Warning

PERIPHERAL ISCHEMIA FOLLOWING COADMINISTRATION WITH STRONG CYP3A4 INHIBITORS Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of dihydroergotamine with strong CYP3A4 inhibitors. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of TRUDHESA with strong CYP3A4 inhibitors is contraindicated [see Contraind...
