Drug & supplement interaction

Fenugreek + Ivermectin

Ivermectin brand names: Stromectol, Mectizan, Sklice, Soolantra.

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 Fenugreek and Ivermectin 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 label for Ivermectin states a food rule worth keeping to, and 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

Fenugreek and Ivermectin

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 Ivermectin 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.
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 congeni... Read the full pregnancy detail
Breastfeeding 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 eviden... Read the full breastfeeding detail

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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 Ivermectin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ivermectin is filed under 4 classifications — including topical drugs, p-glycoprotein substrates, oral 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 Ivermectin’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 — Ivermectin isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Fenugreek and Ivermectin May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    Fenugreek

    “Fenugreek can cause allergic reactions when used orally and topically, and when the powder is inhaled. Orally, fenugreek has caused bronchospasm, diarrhea, and itching, and skin reactions severe enough to require intravenous human immunoglobulin. Topically, fenugreek paste has resulted in facial swelling, wheezing, and numbness around the head.”

Reported for Fenugreek but not commonly for Ivermectin: fainting, an allergic reaction, low blood sugar and bloating or gas.

Effects for Ivermectin come from the ADVERSE REACTIONS section of its FDA label; effects for Fenugreek come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 6,298 voluntary FDA FAERS reports for Ivermectin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

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.

How to take them

Some Ivermectin Products Have a Food Rule — Fenugreek Should Not Break It

At least one FDA label for a product containing Ivermectin says to take it on an empty stomach. Most supplements — Fenugreek included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Ivermectin on its own and move Fenugreek to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ivermectin products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Patients should take tablets on an empty stomach with water.

From the Dosage and Administration section of the FDA label we read for Ivermectin — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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.

About Ivermectin

What Is Ivermectin Used For?

Brand names: Stromectol, Mectizan, Sklice, Soolantra

Ivermectin tablets (including Stromectol) are used to treat two parasitic infections: strongyloidiasis (a roundworm infection of the intestinal tract) and onchocerciasis (river blindness, caused by a parasitic worm spread by blackfly bites). These are prescription uses for serious infections.

Topical ivermectin lotion — sold under several names including RID One and Done, Head Lice Treatment Ivermectin Lotion, Scalp Care Lotions, and others — is applied to the scalp to treat head lice. A separate topical ivermectin cream (1%), available as Soolantra and ivermectin cream 1%, is used to treat the inflammatory pimple-like bumps of rosacea.

Most-Reported Side Effects for Ivermectin

From FAERS, the FDA’s public side-effect reporting system (6,298 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Headache 647 reports
Asthenia 590 reports
Fever 485 reports

Taking Fenugreek and Ivermectin Together: Common Questions

Is it safe to take Fenugreek with Ivermectin?
We do not list a known interaction between Fenugreek and Ivermectin. 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 Fenugreek and Ivermectin have any of the same side effects?
Yes — our sources link each of them separately to 8 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.
Should I take Fenugreek and Ivermectin at the same time of day?
At least one FDA label for a product containing Ivermectin says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Ivermectin on its own and move Fenugreek to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Fenugreek and Ivermectin combination checked?
Interactions in our licensed database are recorded against drug classes. Ivermectin is filed under 4 classifications, and Fenugreek has documented interactions with 9 drug classes — none of Ivermectin'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 — Ivermectin 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 Ivermectin interact with any supplements?
Yes. Ivermectin has documented interactions with 58 supplements in our database — Fenugreek is not one of them. The Ivermectin interaction page linked on this page lists every one, ranked by severity.
