Pokeweed + Phendimetrazine
Phendimetrazine brand names: Plegine, Metra, Weightrol.
We found no known interaction between Pokeweed and Phendimetrazine 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 Phendimetrazine
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 Phendimetrazine 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 Phendimetrazine, 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.

From our pharmacist’s overview on the Phendimetrazine page
“Of the 17 supplements on file for phendimetrazine, an appetite-suppressant stimulant prescribed short term for weight loss, activated charcoal is the one that demands real caution. Charcoal binds medications in the gut and can sharply cut how much of a drug your body absorbs, leaving you with less appetite control than your prescriptio…”

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 Phendimetrazine
What Is Phendimetrazine Used For?
Brand names: Plegine, Metra, Weightrol
Phendimetrazine tartrate is used to help manage exogenous obesity (excess body weight from outside causes like diet and lifestyle) as a short-term addition to a calorie-restricted diet. It is intended for adults with a BMI of 30 or higher, or a BMI of 27 or higher when other risk factors — such as high blood pressure, diabetes, or high cholesterol — are also present.
It is approved for use as monotherapy only, meaning it must not be combined with other weight-loss drugs or stimulants. Both the tablet form and the extended-release capsule form are approved for this purpose. This medication is meant to be used for only a few weeks as part of a broader weight-management plan.
