Interaction report

Bear's Garlic and Butorphanol

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 Butorphanol and Bear's Garlic 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.

Bear's Garlic safety at a glance

Bear's Garlic overall Use caution Generally safe as a food, but supplement-level safety is not well studied.

Pregnancy Use caution Food amounts are likely fine, but avoid concentrated supplements due to lack of safety data.

Breastfeeding Use caution Food amounts are likely fine, but supplement safety is unknown, so use caution.

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

How we checked

Why No Interaction Is Listed for Butorphanol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Butorphanol is filed under 4 classifications — including narcotic drugs, cns depressants, seizure threshold lowering drugs. Bear's Garlic has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Butorphanol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Butorphanol’s Own FDA Label Lists

This is not an interaction — none of it involves Bear's Garlic. These are the most notable effects listed in the ADVERSE REACTIONS section of Butorphanol’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. 10 of them are worth acting on rather than waiting out — marked below.

Dependence or withdrawal symptoms Worth acting on
Serotonin syndrome Worth acting on
Low blood sugar Worth acting on
Hallucinations Worth acting on
Fainting Worth acting on
Confusion Worth acting on
Chest pain Worth acting on
Low mood Worth acting on
Raised blood pressure Worth acting on
Shortness of breath Worth acting on

Showing the 10 most notable of 36 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 Butorphanol. Read the label on DailyMed › Where a percentage is shown, it is the share of 326 voluntary FDA FAERS reports for Butorphanol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Bear's Garlic’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Bear's Garlic side to compare — that is a limit of the record, not a statement that Bear's Garlic has no side effects.

Everything else you take

See Every Supplement That Interacts With Butorphanol

This page covers Bear's Garlic only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Butorphanol page lists 100 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 7 major · 78 moderate · 15 minor.

From our pharmacist’s overview on the Butorphanol page

“Slowed breathing and deep sedation are the risks that tower over any opioid, and most of this list threatens to push butorphanol (Stadol), an opioid pain reliever, in exactly that direction. Of the 100 supplement and herbal ingredients on file, 78 add their own sedative pull, so this page deserves genuine care, not a skim.”

About Bear's Garlic

What is Bear's Garlic?

Seasoning and culinary flavoring
Heart and blood vessel health
Blood pressure support
Digestive complaints
General 'cleansing' or detox traditions

Bear's garlic is a wild relative of garlic enjoyed mainly as a mild-tasting food. Some early laboratory studies hint at heart and blood vessel benefits, but solid human evidence is lacking, so it should be viewed as a flavorful food rather than a proven remedy. As food it is generally well tolerated, but supplements or large amounts have not been well studied for safety.

Allium ursinum · Amaryllidaceae · Leaves and bulb · Fresh leaves, dried herb, tinctures, capsules, juice, teas, culinary pesto

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

Bear's Garlic: dosing

There is no established standardized dose for bear's garlic. As a food, people use the fresh leaves in cooking to taste during its spring season.For supplement forms such as capsules or tinctures, there is no proven medicinal dose.
