Drug & supplement interaction

Pokeweed + Clonazepam

Clonazepam brand names: Klonopin, Rivotril, Ceberclon.

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 Pokeweed and Clonazepam 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.

Pokeweed and Clonazepam

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 Clonazepam and Pokeweed 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 Pokeweed at all — not against Clonazepam, 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.

No Interaction Found — But Data Suggests Pokeweed and Clonazepam 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. 3 of them are worth acting on rather than waiting out — marked below.

  • Seizures / Shortness of breath Worth acting on Additional detail

    Pokeweed

    “Pokeweed is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Orally, all parts of the pokeweed plant can cause nausea, vomiting, cramping, abdominal pain, diarrhea, a burning sensation in the mouth and throat, weakness, hypotension, bloody emesis, bloody diarrhea, tachycardia, difficulty breathing, salivation, urinary incontinence, spasms, convulsions, severe thirst…”

From our pharmacist’s overview on the Clonazepam page

“Clonazepam (Klonopin) slows brain activity to control seizures and panic, and most of what interacts with it pushes in one of two directions: deepening that sedation or changing how much drug is in your blood. This is a list to approach carefully.”

About Pokeweed

What is Pokeweed?

  • Joint pain and arthritis
  • Skin conditions
  • Swollen lymph nodes
  • Respiratory complaints
  • Traditional 'blood cleansing'

Pokeweed is a wild North American plant that is toxic in most of its raw forms, and there is no reliable evidence that it safely treats any condition. Poisonings have occurred from eating the berries, root, or improperly prepared greens. Because of its serious safety risks, most experts recommend avoiding it.

Phytolacca americana · Phytolaccaceae · Root, berries, leaves, and young shoots · Tincture, dried root, capsules, topical preparations, and traditionally cooked greens ('poke sallet')

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

Pokeweed: dosing

There is no established safe dose for pokeweed. Because the plant is toxic and the amount of active and harmful compounds varies widely, no reliable medicinal dose can be recommended.We do not provide dosing for pokeweed because of its poisoning risk. For most people, the safest choice is to avoid pokeweed altogether.

About Clonazepam

What Is Clonazepam Used For?

Brand names: Klonopin, Rivotril, Ceberclon

Clonazepam is approved to treat several types of seizures — including Lennox-Gastaut syndrome (a severe form of epilepsy), akinetic seizures (sudden loss of muscle tone), myoclonic seizures (sudden muscle jerks), and absence seizures (brief lapses of awareness) in patients who haven't responded to other medicines.

It is also approved for panic disorder, with or without agoraphobia (fear of situations that might cause panic). Panic disorder involves repeated, unexpected panic attacks along with ongoing worry about having more attacks.

Most-Reported Side Effects for Clonazepam

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Pokeweed and Clonazepam Together: Common Questions

Is it safe to take Pokeweed with Clonazepam?
We do not list a known interaction between Pokeweed and Clonazepam. 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 Pokeweed and Clonazepam 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. 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.
Does Clonazepam interact with any supplements?
Yes. Clonazepam has documented interactions with 206 supplements in our database — Pokeweed is not one of them. The Clonazepam interaction page linked on this page lists every one, ranked by severity.
