Drug & supplement interaction

Basil + Diethylpropion

Diethylpropion brand names: Radtue, Tenuate, Durad, Tenuate Dosepan.

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 Basil and Diethylpropion 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.

Interaction report

Basil 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 Basil 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.

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.

How we checked

Why No Interaction Is Listed for Diethylpropion

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diethylpropion is filed under 2 classifications — stimulant drugs, oral drugs. Basil has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Diethylpropion’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Basil and Diethylpropion May Share a Side Effect

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.

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 Basil

What is Basil?

Basil
  • Digestive upset and gas
  • Stress and anxiety
  • Antimicrobial support
  • Cold and cough symptoms
  • Headache
  • General antioxidant support

Basil is a popular cooking herb that is generally safe in the amounts used in food. While it has a long history of traditional medicinal use and contains antioxidant compounds, strong human evidence for most health claims is limited. Talk with your pharmacist or doctor before using concentrated supplements or essential oils.

Ocimum basilicum · Lamiaceae · Leaves, flowering tops, seeds, and essential oil · Fresh or dried leaves, culinary herb, tea, capsules, extracts, and essential oil

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

Basil: dosing

There is no well-established standard medicinal dose for basil. As a food and seasoning, it is used freely to taste with no special precautions for most people.For supplements, teas, or extracts, the right amount is not clearly defined by research. Follow the directions on the product label and do not exceed them.

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.

Taking Basil and Diethylpropion Together: Common Questions

Is it safe to take Basil with Diethylpropion?
We do not list a known interaction between Basil and Diethylpropion. 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 Basil and Diethylpropion have any of the same side effects?
Yes — our sources link each of them separately to one 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.
How was the Basil and Diethylpropion combination checked?
Interactions in our licensed database are recorded against drug classes. Diethylpropion is filed under 2 classifications, and Basil has documented interactions with 2 drug classes — none of Diethylpropion's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Basil interact with any other medications?
Yes. Basil has 289 documented drug interactions in our database — Diethylpropion is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Diethylpropion interact with any supplements?
Yes. Diethylpropion has documented interactions with 61 supplements in our database — Basil is not one of them. The Diethylpropion interaction page linked on this page lists every one, ranked by severity.
