Drug Interactions

7.1 Ergot-Containing Drugs Including Other 5-HT1B/1D Agonists

Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine [DHE] or methysergide) and RELPAX within 24 hours of each other is contraindicated. Concomitant use of other 5-HT1 agonists within 24 hours of RELPAX treatment is contraindicated [seeContraindications (4)].

7.2 CYP3A4 Inhibitors

Potent CYP3A4 inhibitors significantly increase the exposure of RELPAX. Relpax should not be used within at least 72 hours of treatment with potent CYP3A4 inhibitors [see Contraindications (4) and Clinical Pharmacology (12.3)].

7.3 Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome

Cases of serotonin syndrome have been reported during co-administration of triptans and SSRIs, SNRIs, TCAs and MAO inhibitors [seeWarnings and Precautions (5.7)].
