Arrach and Lasmiditan Succinate

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lasmiditan Succinate and Arrach in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

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 Arrach

What is Arrach?

Arrach
  • Painful menstruation
  • Nervous complaints
  • Digestive upset
  • Wound care
  • Insect repellent

Arrach (Chenopodium vulvaria) is a strong-smelling European herb that has been used in traditional folk medicine, mainly for menstrual and nervous complaints. There is very little modern scientific evidence to show that it works or is safe, so it is not recommended, especially during pregnancy or breastfeeding. Talk to your pharmacist or doctor before using any herbal product.

An interaction check asks whether these two react with each other — it does not ask whether Arrach is a good idea for someone in your situation. Here is what our Arrach record says about it on its own.

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.
