Raspberry Ketone and Diethylpropion

Here is the interaction we found between these two, with the evidence behind it.

Moderate

STIMULANT DRUGS

Why this applies to Diethylpropion

Diethylpropion falls under STIMULANT DRUGS — the group Raspberry Ketone interacts with.

Theoretically, raspberry ketone might increase the risk of adverse cardiovascular effects with stimulant drugs.
Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Heart palpitations, elevated blood pressure, coronary vasospasm, pulseless electrical activity arrest, and resistant polymorphic ventricular tachycardia have been reported in patients taking raspberry ketone.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind: diethylpropion is itself a stimulant that curbs appetite. Raspberry ketone is chemically similar to synephrine, a mild stimulant of its own. So when you stack the two, you may be adding one stimulant effect on top of another. That's where the worry comes from.

In practical terms, this could mean a faster or pounding heartbeat, a bump in blood pressure, jitteriness, or trouble sleeping. The scary events listed in the research (like dangerous heart rhythms) are rare and based mostly on anecdotal reports, not solid studies, so I don't want to alarm you. Still, since both products push your heart and pressure in the same direction, I'd run this combo by your doctor or pharmacist before pairing them, especially since raspberry ketone hasn't been shown to actually help with weight loss.

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 Raspberry Ketone

What is Raspberry Ketone?

Raspberry Ketone
  • Weight loss
  • Fat burning
  • Boosting metabolism
  • Appetite support
  • General 'fat-burner' supplement

Raspberry ketone is a natural aroma compound found in red raspberries that is heavily marketed for weight loss, but there is no good human evidence that it helps people lose weight. Most claims come from lab and animal studies using doses far higher than what you could get from food or typical supplements. If you choose to try it, talk to your pharmacist or doctor first.

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.
