The bottom line No known interaction

We found no known interaction between Acai 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.

Interaction report

Acai 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 Acai 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.

Acai safety at a glance

Acai overall Use caution Acai is generally well tolerated as a food, but supplement quality and high-dose effects are not well studied.

Pregnancy Use caution Acai as a food is likely fine, but concentrated supplements have not been studied in pregnancy, so it is best to use caution.

Breastfeeding Use caution There is not enough safety information on acai supplements during breastfeeding, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Acai has documented interactions with 1 drug class — the most serious being antidiabetes 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.

Keep it in perspective

Acai has 86 moderate known drug interactions in our database — Diethylpropion isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

What Diethylpropion’s Own FDA Label Lists

This is not an interaction — none of it involves Acai. These are the most notable effects listed in the ADVERSE REACTIONS section of Diethylpropion’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

A stroke or mini-stroke Worth acting on
Pain or burning when passing urine Worth acting on
An irregular heartbeat Worth acting on
Low mood Worth acting on
Raised blood pressure Worth acting on
Shortness of breath Worth acting on
Hives Worth acting on
A low white blood cell count Worth acting on
Bleeding or bruising Worth acting on
Passing urine more often

Showing the 10 most notable of 30 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Diethylpropion. Read the label on DailyMed › Acai’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Acai side to compare — that is a limit of the record, not a statement that Acai has no side effects.

Overlapping uses

What Diethylpropion Is Prescribed For, and What Acai Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Diethylpropion is a prescription medicine with approved uses on its FDA label. Acai is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Diethylpropion is prescribed for: 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.

Acai has been studied for:

Obesity studied, not established Acai has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Acai for obesity

It is unclear if oral black seed is beneficial for improving metabolic indices in overweight individuals.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Diethylpropion on your own; if you are taking Acai for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Diethylpropion

This page covers Acai only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Diethylpropion page lists 61 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Peyote (major), Rauvolfia Vomitoria (major) and Sida Cordifolia (major).

By severity: 5 major · 43 moderate · 13 minor.

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 Acai

What is Acai?

Antioxidant support
Weight loss
Energy and vitality
Heart health
General wellness ('superfood')

Acai is a nutritious Amazonian berry rich in antioxidants and healthy fats, and it is fine to enjoy as a food. However, strong human evidence is lacking for the bold health claims often attached to acai supplements, including weight loss and disease prevention.

Euterpe oleracea · Arecaceae · Fruit (berry) and its pulp · Juice, frozen pulp, smoothie packs, powder, capsules, tablets

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

Acai: dosing

There is no officially established or standardized dose for acai. Amounts used in studies and products vary widely depending on the form (juice, pulp, powder, or capsule).The best approach is to follow the directions on the product label and not exceed the recommended amount.

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

How was the Acai and Diethylpropion combination checked?

Diethylpropion is filed under 2 classifications, and Acai has documented interactions with 1 drug class — 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.
