Drug & supplement interaction

Levant Berry + 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 Levant Berry 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.

Levant Berry 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 Levant Berry 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Levant Berry at all — not against Dextroamphetamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

No Interaction Found — But Data Suggests Levant Berry 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. One of them is worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on Additional detail

See Every Supplement That Interacts With Dextroamphetamine

This page covers Levant Berry 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 Levant Berry

What is Levant Berry?

  • Historically as a fish poison (stunning fish)
  • Topical preparations for lice and skin parasites
  • Traditional remedies for epilepsy and convulsions
  • Old preparations for skin conditions
  • Source of the compound picrotoxin

Levant Berry (Anamirta cocculus) is a highly toxic plant fruit that contains picrotoxin, a powerful poison once used to stun fish and, in the past, as a crude medicine. It is dangerous and is not considered a safe dietary supplement; it should not be taken internally.

Anamirta cocculus · Menispermaceae · Dried ripe fruit (berry/seed) · Historically used as a crude dried berry; today rarely used and not recommended internally

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

Levant Berry: dosing

There is no established or recommended dose for Levant Berry, because it is toxic and not used as a safe supplement. We cannot provide a dose and strongly advise against taking it internally in any amount.If you encounter a product that lists this ingredient, do not use it without first checking with a pharmacist or doctor. A licensed health professional can help you choose safer, proven options.

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.

Do Levant Berry and Dextroamphetamine have any of the same side effects?
Yes — our sources link each of them separately to 7 of the same effects. That is not an interaction: neither changes how your body handles the other.
