St John's wort and triptans
Last reviewed 01/2018
St John's wort (SJW) interacts with triptans (sumatriptan, naratriptan, rizatriptan, zolmitriptan) and may lead to increased serotonergic effects with an increased incidence of adverse reactions.
If a patient is taking SJW and triptans it is advised that the patient stops taking SJW.
