Corydalis Yanhusuo and Lasmiditan Succinate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Lasmiditan Succinate

Lasmiditan Succinate falls under CNS DEPRESSANTS — the group Corydalis Yanhusuo interacts with.

Theoretically, Corydalis yanhusuo might increase the sedative effects of CNS depressants.
Corydalis yanhusuo contains berberine. Animal research suggests that berberine may have sedative effects. Theoretically, Corydalis yanhusuo might also have CNS depressants effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Lasmiditan (Reyvow) already tends to make people feel drowsy, dizzy, or a bit foggy when they take it for a migraine. Corydalis yanhusuo may have its own calming, sedative-like effect on the brain. So if you pair the two, the worry is that the sleepiness and lightheadedness could stack up and feel stronger.

One important note: this concern is mostly theoretical, based on how these compounds behave in lab and animal studies, not on solid human research. Lasmiditan is not a prodrug, so this isn't about one changing the other's blood levels. It's simply two things that can each make you drowsy. To be safe, don't drive or do anything risky until you know how you feel, and check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Lasmiditan Succinate page

“Sedation is the thread running through most of this page. Lasmiditan (Reyvow) treats migraine attacks and is drowsy-making enough that patients are told not to drive for eight hours after a dose, so the many supplements here with sedative pull of their own deserve genuine wariness; kava and even a beer or glass of wine carry major rati…”

About Corydalis Yanhusuo

What is Corydalis Yanhusuo?

  • Pain relief
  • Menstrual cramps
  • Headache
  • Stress and sleep support
  • Stomach and abdominal discomfort

Corydalis yanhusuo is a traditional Chinese herb used mainly for pain.

About Lasmiditan

What Is Lasmiditan Used For?

Brand name: Reyvow

Reyvow (lasmiditan) is used to treat migraine attacks in adults, whether or not the migraine comes with an aura (visual or sensory symptoms that can appear before or during the headache). It is taken when a migraine starts — not used daily to prevent migraines from happening.

Reyvow is not intended for preventive (daily) migraine therapy. It is meant to stop an attack that has already begun.
