Drug & supplement interaction

Magnolia + Dextroamphetamine

Dextroamphetamine brand name: Dexedrine.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Magnolia and Dextroamphetamine 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Magnolia and Dextroamphetamine

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 Dextroamphetamine and Magnolia 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 Dextroamphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dextroamphetamine is filed under 7 classifications — including amphetamines, stimulant drugs, serotonergic drugs. Magnolia has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and cns depressants (moderate) — and none of Dextroamphetamine’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

What to actually watch for

No Interaction Found — But Data Suggests Magnolia and Dextroamphetamine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

See Every Supplement That Interacts With Dextroamphetamine

This page covers Magnolia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dextroamphetamine page lists 129 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Lithium (major), Peyote (major) and Rauvolfia Vomitoria (major).

By severity: 6 major · 100 moderate · 23 minor.

From our pharmacist’s overview on the Dextroamphetamine page

“Dextroamphetamine (Dexedrine) is a stimulant for ADHD and narcolepsy, and I read this list with genuine wariness. Six of the 129 ingredients rate major, most of them because other stimulants, ephedra being the clearest, pile extra heart rate and blood pressure on top of what the drug already produces.”

About Magnolia

What is Magnolia?

Magnolia
  • Anxiety and stress
  • Sleep problems
  • Digestive upset
  • Inflammation
  • Nasal congestion and allergies (flower bud)

Magnolia bark and flower buds have a long history in traditional Chinese and Japanese medicine, often for stress, sleep, and digestion. Modern human research is still limited, so we can't be sure how well it works for most uses. Talk with your pharmacist or doctor before trying it, especially if you take other medicines or are pregnant.

Magnolia officinalis · Magnoliaceae · Bark and flower buds · Capsules, tablets, tea, tinctures, and some toothpastes or skin products

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

Magnolia: dosing

There is no well-established standard dose of Magnolia. Products vary widely in how they are prepared and how concentrated they are, and many supplements combine Magnolia with other ingredients.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

About Dextroamphetamine

What Is Dextroamphetamine Used For?

Brand name: Dexedrine

Dextroamphetamine treats two conditions: ADHD and narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness). It is available in multiple forms — tablets, extended-release capsules, oral solution, and a skin patch — and the approved age ranges vary by product.

Oral tablets (Zenzedi, generic) and oral solutions (Procentra, generic) are approved for ADHD in children as young as 3 years old and for narcolepsy. Extended-release capsules (Dexedrine, generic) are approved for ADHD in children ages 6 to 16 and for narcolepsy. Xelstrym, the transdermal patch, is approved only for ADHD — in adults and children ages 6 and older — and is not indicated for narcolepsy.

Taking Magnolia and Dextroamphetamine Together: Common Questions

Is it safe to take Magnolia with Dextroamphetamine?
We do not list a known interaction between Magnolia and Dextroamphetamine. 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.
Do Magnolia and Dextroamphetamine have any of the same side effects?
Yes — our sources link each of them separately to 6 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Magnolia and Dextroamphetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Dextroamphetamine is filed under 7 classifications, and Magnolia has documented interactions with 2 drug classes — none of Dextroamphetamine'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 Magnolia interact with any other medications?
Yes. Magnolia has 351 documented drug interactions in our database — Dextroamphetamine 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 Dextroamphetamine interact with any supplements?
Yes. Dextroamphetamine has documented interactions with 129 supplements in our database — Magnolia is not one of them. The Dextroamphetamine interaction page linked on this page lists every one, ranked by severity.
