Beth Root and Sodium Phenylbutyrate, Taurursodiol

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 Sodium Phenylbutyrate, Taurursodiol and Beth Root 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Beth Root at all — not against Sodium Phenylbutyrate, Taurursodiol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Beth Root Itself Has Been Linked To

This is not an interaction — nothing below involves Sodium Phenylbutyrate, Taurursodiol. It is the side-effect record for Beth Root on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Beth Root, this list is the first place to look.

  • Vomiting Additional detail

    “Orally, ingestion of large amounts of the plant or volatile oil might produce GI irritation severe enough to cause vomiting (12,18). In pregnant women, the drastic purgative effects can cause reflex uterine contractions.

    Topically, beth root causes extreme irritation (18).”

Everything above comes from the Natural Medicines adverse-effect record for Beth Root — expand a row for the licensed statement it rests on. We haven’t matched Sodium Phenylbutyrate, Taurursodiol to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Sodium Phenylbutyrate, Taurursodiol.

From our pharmacist’s overview on the Sodium Phenylbutyrate, Taurursodiol page

“Relyvrio (sodium phenylbutyrate and taurursodiol) treats ALS, a disease where losing part of a dose is a real loss, and that is exactly what most of these 20 interactions threaten, so give them a hard look before adding any supplement. Seventeen involve ingredients, mostly fibers, gums, and mucilage-rich herbs, that can change how much…”

About Beth Root

What is Beth Root?

  • Heavy menstrual bleeding
  • Menstrual cramps
  • Childbirth and postpartum bleeding
  • Wounds and skin irritation
  • Diarrhea

Beth root is a traditional North American plant remedy historically used by Indigenous peoples and folk herbalists, mostly for menstrual and bleeding-related complaints. There is very little modern scientific evidence to show it works for any condition, and its safety has not been well studied, so caution is advised—especially during pregnancy and breastfeeding.

About Sodium Phenylbutyrate and Taurursodiol

What Is Sodium Phenylbutyrate and Taurursodiol Used For?

Brand name: Relyvrio

  • Sodium phenylbutyrate and taurursodiol is used for the treatment of amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease; a condition in which the nerves that control muscle movement slowly die, causing the muscles to shrink and weaken). Sodium phenylbutyrate is a histone deacetylase inhibitor. Taurursodiol is a bile acid. It is not known exactly how the combination of sodium phenylbutyrate and taurursodiol works, but it may reduce the breakdown and death of nerve cells associated with the worsening of ALS symptoms.
