No Known Interaction
The bottom line No known interaction

We found no known interaction between Fenugreek and Amphetamine 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.

Fenugreek and Amphetamine

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 Amphetamine and Fenugreek 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.

Fenugreek safety at a glance

Fenugreek overall Use caution Generally well tolerated in food amounts, but supplement doses may cause side effects and aren't right for everyone.

Pharmacist analysis

Fenugreek is generally considered relatively safe in regard to potential drug interactions.

Nevertheless, interactions are possible between fenugreek and:

  • 'Blood-thinning' drugs
  • Drugs that lower blood pressure
  • Drugs that low blood sugar

Fenugreek contains some components that can prevent blood from clotting. However, there is not enough research to confirm whether the amount of these components present in common fenugreek products can have a clinically significant effect.

Fenugreek may also have an additive effect with blood sugar-lowering medication and blood pressure-lowering medication.

All of these potential interactions are documented individually on our specific drug-herbal interaction pages.

How we checked

Why No Interaction Is Listed for Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. Fenugreek has documented interactions with 9 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and clopidogrel (plavix) (moderate) — and none of Amphetamine’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

Fenugreek Does Interact With Other Medications

Fenugreek has 224 moderate, 165 minor known drug interactions in our database — Amphetamine isn’t one of them. If you take anything else, check it against the full list below.

Special populations

Fenugreek in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally in amounts greater than those found in food. Fenugreek has potential oxytoxic and uterine stimulant activity. There are case reports of congenital malformations, including hydrocephalus, anencephaly, cleft palate, and spina bifida, after consumption of fenugreek seeds during pregnancy. Consumption of fenugreek immediately prior to delivery may cause the neonate to have unusual body odor. Although this does not appear to cause long-term sequelae, it may be misdiagnosed as maple syrup urine disease.

Lactation Possibly Safe

When used orally to stimulate lactation, short-term. Although most available clinical studies lack safety testing in the lactating parent or infant, some evidence suggests that taking fenugreek 1725 mg three times daily orally for 21 days does not cause negative side effects in the infant.

Overlapping uses

What Amphetamine Is Prescribed For, and What Fenugreek Has Been Studied For

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

Amphetamine is prescribed for: Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group. Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.

Fenugreek has been studied for:

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

    Fenugreek for obesity

    Small clinical studies suggest that oral fenugreek seed or fiber may increase satiety and decrease caloric intake.

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 Amphetamine on your own; if you are taking Fenugreek for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Fenugreek

What is Fenugreek?

Fenugreek
  • Blood sugar control
  • Boosting breast milk supply
  • High cholesterol
  • Digestive upset
  • Low testosterone or libido

Fenugreek is a common kitchen spice that is also taken as a supplement, mainly for blood sugar, cholesterol, and to support breast milk production. Some early research is encouraging for blood sugar, but overall the evidence is mixed and far from settled. It is generally well tolerated as food, but talk with your pharmacist or doctor before using it as a supplement, especially if you are pregnant.

Trigonella foenum-graecum · Fabaceae · Seeds and leaves · Capsules, powder, seeds, tea, extracts, and as a culinary spice

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

Fenugreek: dosing

There is no official standardized dose for fenugreek, and the right amount depends on the product and reason for use. Studies have used a wide range of doses and different preparations, so there is no single agreed-upon amount.The best approach is to follow the directions on the product label and not exceed them.

Taking Fenugreek and Amphetamine Together: Common Questions

Is it safe to take Fenugreek with Amphetamine?
We do not list a known interaction between Fenugreek and Amphetamine. 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.
Are Fenugreek and Amphetamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Fenugreek in each. That is a conversation for your prescriber, especially if Amphetamine is being adjusted to a target.
How was the Fenugreek and Amphetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Amphetamine is filed under 6 classifications, and Fenugreek has documented interactions with 9 drug classes — none of Amphetamine'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 Fenugreek interact with any other medications?
Yes. Fenugreek has 389 documented drug interactions in our database — Amphetamine 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 Amphetamine interact with any supplements?
Yes. Amphetamine has documented interactions with 130 supplements in our database — Fenugreek is not one of them. The Amphetamine interaction page linked on this page lists every one, ranked by severity.
