Datura Wrightii and Alosetron

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 Alosetron and Datura Wrightii 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.

How we checked

Why No Interaction Is Listed for Alosetron

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alosetron is filed under 3 classifications — serotonergic drugs, serotonergic drugs, oral drugs. Datura Wrightii has documented interactions with 2 drug classes — the most serious being anesthesia (moderate) and anticholinergic drugs (moderate) — and none of Alosetron’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 Datura Wrightii Itself Has Been Linked To

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

Everything above comes from the Natural Medicines adverse-effect record for Datura Wrightii — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Alosetron’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Alosetron column appears here.

From our pharmacist’s overview on the Alosetron page

“Alosetron (Lotronex) treats severe diarrhea-predominant IBS by acting on serotonin receptors in the gut, and that is where most of its 38 supplement interactions come from. Twenty of the ingredients, 5-HTP among them, raise serotonin on their own, and stacking them on a serotonin-acting drug is a combination I want you to treat with re…”

About Datura Wrightii

What is Datura Wrightii?

  • Traditional ritual and ceremonial use
  • Pain relief (traditional/topical)
  • Asthma and breathing complaints (historical)
  • Hallucinogenic/psychoactive effects
  • Skin and wound applications (folk use)

Datura wrightii (sacred datura or jimsonweed relative) is a highly poisonous desert plant that has been used in some traditional and ceremonial settings. It is not a safe dietary supplement — even small amounts can cause severe poisoning, hallucinations, and death. We strongly advise against using it.

Datura wrightii · Solanaceae · Leaves, flowers, seeds, and roots (all parts are toxic) · Traditional ceremonial preparations, topical pastes, smoked plant material (not a standard commercial supplement)

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

Datura Wrightii: dosing

There is no safe or established dose of Datura wrightii. Because the amount of toxic alkaloids varies enormously between plants and plant parts, there is no way to measure a safe amount at home.We do not provide dosing for this plant because we cannot recommend its use.
