The bottom line No known interaction

We found no known interaction between Sweet Gale and Odevixibat in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Odevixibat states a food rule worth keeping to.

Sweet Gale and Odevixibat

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 Odevixibat and Sweet Gale 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 Sweet Gale at all — not against Odevixibat, 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.

Sweet Gale safety at a glance

Sweet Gale overall Use caution Limited safety data and a volatile oil that may be toxic in higher amounts.
Pregnancy Avoid Traditionally avoided in pregnancy and not enough safety data exists.
Breastfeeding Avoid No reliable safety information during breastfeeding, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Odevixibat’s Own FDA Label Lists

This is not an interaction — none of it involves Sweet Gale. These are the most notable effects listed in the ADVERSE REACTIONS section of Odevixibat’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 6 of them are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes Worth acting on mentioned in 5.4% of FDA reports for Odevixibat
  • Bone thinning Worth acting on
  • Dehydration Worth acting on
  • Liver problems Worth acting on mentioned in 5.7% of FDA reports for Odevixibat
  • Anemia Worth acting on
  • Bleeding or bruising Worth acting on
  • Heartburn
  • Diarrhea mentioned in 24.0% of FDA reports for Odevixibat
  • Weight loss
  • Stomach pain mentioned in 12.0% of FDA reports for Odevixibat

Showing the 10 most notable of 15 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Odevixibat. Read the label on DailyMed › Where a percentage is shown, it is the share of 350 voluntary FDA FAERS reports for Odevixibat that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Sweet Gale’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Sweet Gale side to compare — that is a limit of the record, not a statement that Sweet Gale has no side effects.

How to take them

Some Odevixibat Products Have a Food Rule — Sweet Gale Should Not Break It

At least one FDA label for a product containing Odevixibat says to take it with food. If you take Sweet Gale on an empty stomach out of habit, keep them separate — and take Odevixibat with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Odevixibat products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.2 ) Preparation and Administration Instructions Administer BYLVAY in the morning with a meal.

From the Dosage and Administration section of the FDA label we read for Odevixibat — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Overlapping uses

What Odevixibat Is Prescribed For, and What Sweet Gale Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Odevixibat is a prescription medicine with approved uses on its FDA label. Sweet Gale is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Odevixibat is prescribed for: Bylvay (odevixibat) capsules are used to treat pruritus (intense, chronic itching caused by bile buildup in the body) in patients with two rare liver conditions. For progressive familial intrahepatic cholestasis (PFIC), Bylvay is approved for patients 3 months of age and older. For Alagille syndrome (ALGS), Bylvay is approved for patients 12 months of age and older. There is an important limitation: Bylvay is not recommended for a specific subgroup of PFIC type 2 patients who have certain genetic variants that result in a non-functional or completely absent bile salt export pump (BSEP) protein.

  • Pruritus studied, not established Sweet Gale has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Sweet Gale for pruritus

    Although there has been interest in using oral sweet gale for pruritus, there is insufficient reliable information about the clinical effects of sweet gale for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Odevixibat on your own; if you are taking Sweet Gale for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Sweet Gale

What is Sweet Gale?

  • Insect repellent
  • Digestive complaints
  • Flavoring for food and beverages
  • Skin and itch relief (traditional)
  • Aromatic and fragrance use

Sweet gale is an aromatic shrub long used as an insect repellent and a flavoring herb, but there is very little solid human research supporting any health benefit. Its essential oil is considered potentially toxic, so internal use should be approached with great caution and avoided in pregnancy. Talk to a pharmacist or doctor before using it.

Myrica gale · Myricaceae · Leaves, branches, fruit (catkins), and wax/essential oil · Tea, dried leaves, essential oil, flavoring agent

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

Sweet Gale: dosing

There is no established or standardized dose for sweet gale. Because reliable human research is lacking, no safe and effective amount has been defined for any health condition.If you choose to use a sweet gale product, follow the directions on the label and do not exceed them. Avoid swallowing the essential oil.

Taking Sweet Gale and Odevixibat Together: Common Questions

Is it safe to take Sweet Gale with Odevixibat?
We do not list a known interaction between Sweet Gale and Odevixibat. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Sweet Gale and Odevixibat at the same time of day?
At least one FDA label for a product containing Odevixibat says to take it with food. If you take Sweet Gale on an empty stomach out of habit, keep them separate and take Odevixibat with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Odevixibat products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Sweet Gale and Odevixibat used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Sweet Gale in each. That is a conversation for your prescriber, especially if Odevixibat is being adjusted to a target.
Does Odevixibat interact with any supplements?
Yes. Odevixibat has documented interactions with 17 supplements in our database — Sweet Gale is not one of them. The Odevixibat interaction page linked on this page lists every one, ranked by severity.
