The bottom line No known interaction

We found no known interaction between Kratom and Tubocurarine 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.

Interaction report

Kratom and Tubocurarine

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 Tubocurarine and Kratom 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.

Kratom safety at a glance

Breastfeeding Avoid Kratom compounds may pass into breast milk and should be avoided while nursing.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Tubocurarine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tubocurarine is filed under a single classification — skeletal muscle relaxants. Kratom has documented interactions with 11 drug classes — the most serious being cns depressants (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (moderate) — and none of Tubocurarine’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.

Keep it in perspective

Kratom Does Interact With Other Medications

Kratom has 983 moderate, 12 minor known drug interactions in our database — Tubocurarine isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

What Kratom Itself Has Been Linked To

This is not an interaction — nothing below involves Tubocurarine. It is the side-effect record for Kratom on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Kratom, this list is the first place to look. 8 entries are worth acting on rather than waiting out — marked below.

“Orally, kratom has been associated with aggression, agitation, altered mental status, anxiety, delusions, depression, hallucinations, insomnia, irritability, paranoia, restlessness, sedation, and suicidal ideation, in case reports and case series.”

Kratom in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally. There have been multiple case reports of neonatal abstinence syndrome in the infants of those who used kratom during pregnancy. Animal research suggests that kratom crosses the placenta.

By severity: 1 major · 2 moderate.

From our pharmacist’s overview on the Tubocurarine page

“Tubocurarine is not a pill you pick up at the pharmacy; it is a paralyzing agent given during surgery so the anesthesia team can relax your muscles, and that setting is exactly why this short list deserves genuine care. All three flagged ingredients push in the same direction, deepening or stretching out the paralysis the drug causes.”

About Kratom

What is Kratom?

Pain relief
Opioid withdrawal symptoms
Anxiety and stress
Low energy or fatigue
Mood enhancement

Kratom is a Southeast Asian plant whose leaves act on the brain's opioid receptors and can produce both stimulant-like and opioid-like effects. It is not approved or proven safe by health regulators, carries real risks of dependence and serious harm, and its legal status varies widely. Talk to a pharmacist or doctor before considering it.

Mitragyna speciosa · Rubiaceae · Leaves · Dried leaf powder, capsules, tablets, brewed tea, liquid extracts, and concentrated gummies

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

Kratom: dosing

There is no established safe or standardized dose for kratom. The strength of products varies widely, and the amount of active compounds can differ greatly from one batch to another, even within the same brand.Because of these unknowns and the real risks of dependence and harm, we cannot recommend a specific amount. Avoid mixing it with alcohol, opioids, sedatives, or other substances.

Taking Kratom and Tubocurarine Together: Common Questions

Is it safe to take Kratom with Tubocurarine?

We do not list a known interaction between Kratom and Tubocurarine. 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.

How was the Kratom and Tubocurarine combination checked?

Interactions in our licensed database are recorded against drug classes. Tubocurarine is filed under 1 classification, and Kratom has documented interactions with 11 drug classes — none of Tubocurarine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Kratom interact with any other medications?

Yes. Kratom has 995 documented drug interactions in our database — Tubocurarine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Does Tubocurarine interact with any supplements?

Yes. Tubocurarine has documented interactions with 3 supplements in our database — Kratom is not one of them. The Tubocurarine interaction page linked on this page lists every one, ranked by severity.
