Interaction report

Datura Wrightii and Interferon Beta-1a

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 Interferon Beta-1a 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 Interferon Beta-1a

Interactions in our licensed database are recorded against drug classes, not just single drug names. Interferon Beta-1a is filed under 2 classifications — photosensitizing drugs, hepatotoxic drugs. Datura Wrightii has documented interactions with 2 drug classes — the most serious being anesthesia (moderate) and anticholinergic drugs (moderate) — and none of Interferon Beta-1a’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 Datura Wrightii Itself Has Been Linked To

This is not an interaction — nothing below involves Interferon Beta-1a. 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.

See Every Supplement That Interacts With Interferon Beta-1a

This page covers Datura Wrightii only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Interferon Beta-1a page lists 57 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Beer (major), Siberian Cocklebur (major), Wine (major), Alfalfa (moderate) and Angelica Archangelica (moderate).

By severity: 3 major · 53 moderate · 1 minor.

From our pharmacist’s overview on the Interferon Beta-1a page

“Siberian cocklebur, an herb tied to documented cases of liver failure, is the first name to know for anyone injecting interferon beta-1a (Rebif, Avonex) for multiple sclerosis. Interferon beta-1a can strain the liver on its own, which is why prescribers order routine liver blood tests, and 38 of the 57 supplements on file carry that sa…”

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.

About Interferon Beta-1a Intramuscular Injection

What Is Interferon Beta-1a Intramuscular Injection Used For?

Brand names: Rebif, Avonex

Interferon beta-1a intramuscular injection is used to treat adults with various forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including:
- clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours),
- relapsing-remitting forms (course of disease where symptoms flare up from time to time), or
- secondary progressive forms (course of disease where relapses occur more often).
Interferon beta-1a is in a class of medications called immunomodulators. It works by decreasing inflammation and preventing nerve damage that may cause symptoms of multiple sclerosis.

Most-Reported Side Effects for Interferon Beta-1a

From FAERS, the FDA’s public side-effect reporting system (192,069 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Multiple sclerosis relapse 15,851 reports

Influenza like illness 13,253 reports
