Sweet Sumac and Diethylpropion

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 Diethylpropion and Sweet Sumac 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 Sweet Sumac at all — not against Diethylpropion, 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

What Sweet Sumac Itself Has Been Linked To

This is not an interaction — nothing below involves Diethylpropion. It is the side-effect record for Sweet Sumac on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Sweet Sumac, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

    “Orally, infections of the urogenital tract have been reported in women with overactive bladder who were taking a combination product (Granu Fink femina, Omega Pharma) containing sweet sumac bark extract, pumpkin seed oil, and hops cone extract. It is unclear if these adverse effects were due to sweet sumac, other ingredients, or the combination.”

Everything above comes from the Natural Medicines adverse-effect record for Sweet Sumac — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Diethylpropion’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Diethylpropion column appears here.

From our pharmacist’s overview on the Diethylpropion page

“Diethylpropion (Tenuate) is an appetite suppressant that works by revving up the nervous system, and that mechanism is why its interaction list calls for real vigilance. Of the 61 supplements and herbs on file, 44 add their own stimulant push, raising the risk of high blood pressure, a pounding heart, and sleeplessness.”

About Sweet Sumac

What is Sweet Sumac?

  • Urinary complaints
  • Diarrhea
  • Excessive urination or bedwetting
  • Sore throat and mouth rinse
  • Mild bleeding

Sweet Sumac (Rhus aromatica) is a North American shrub used in traditional and folk medicine, mostly for urinary and digestive complaints. There is very little modern human research to confirm that it works for any condition, so its benefits remain unproven. Because it belongs to the same plant family as poison ivy, talk with a pharmacist or doctor before using it.

Rhus aromatica · Anacardiaceae · Bark of the root, leaves, and berries · Dried bark, tea, tincture, liquid extract

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

Sweet Sumac: dosing

There is no established, standardized dose for Sweet Sumac. It has traditionally been taken as a tea, tincture, or liquid extract made from the root bark or leaves, but reliable dosing guidelines from clinical research are not available.If you choose to use a commercial product, follow the directions on the label and do not exceed the suggested amount.

About Diethylpropion

What Is Diethylpropion Used For?

Brand names: Radtue, Tenuate, Durad, Tenuate Dosepan

Diethylpropion is used to help manage exogenous obesity (excess body weight from outside factors like diet) in adults with a body mass index (BMI) of 30 or higher who haven't lost enough weight through diet and exercise alone. It is meant to be used for only a few weeks as part of a calorie-restricted diet plan.

All available tablet products — both the immediate-release tablets and the extended-release tablets — are approved for this purpose. Each is approved for use as a single medication only; combining diethylpropion with any other weight-loss drug is not allowed.
