Baikal Skullcap and Lasmiditan Succinate

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

Minor

CNS DEPRESSANTS

Why this applies to Lasmiditan Succinate

Lasmiditan Succinate falls under CNS DEPRESSANTS — the group Baikal Skullcap interacts with.

Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the gist for these two together: Reyvow already tends to make people drowsy and a bit foggy, and it can cause dizziness too. Baikal skullcap, in lab and animal studies, seems to nudge the same calming brain pathway (the GABA system). So in theory, taking them together could stack that sleepiness and leave you feeling more groggy, lightheaded, or slow to react than usual.

That said, this is a very weak, theoretical concern. The evidence comes from test-tube and animal work, not from people, and early human studies haven't actually shown meaningful sedation from the herb. Reyvow itself already carries driving warnings, so the bigger point is just to see how you feel before driving. If you want to use both, run it by your pharmacist or doctor first.

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…”
