No Known Interaction

The bottom line No known interaction

We found no known interaction between Dyer's Broom and Fenofibrate 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

Dyer's Broom and Fenofibrate

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 Fenofibrate and Dyer's Broom 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 Fenofibrate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fenofibrate is filed under 3 classifications — cytochrome p450 2c9 (cyp2c9) inhibitors, hepatotoxic drugs, oral drugs. Dyer's Broom has documented interactions with 1 drug class — the most serious being caffeine (moderate) — and none of Fenofibrate’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 Dyer's Broom and Fenofibrate 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.

Reported for Dyer's Broom but not commonly for Fenofibrate: vomiting and diarrhea.

Effects for Fenofibrate come from the ADVERSE REACTIONS section of its FDA label; effects for Dyer's Broom come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 35,249 voluntary FDA FAERS reports for Fenofibrate 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.

From our pharmacist’s overview on the Fenofibrate page

“Fenofibrate (Tricor, Antara) is a cholesterol and triglyceride medicine that can strain the liver on its own, so this list of 59 supplements deserves genuine care rather than a shrug. Most of it, 38 ingredients, involves herbs that also stress the liver, ashwagandha among them, and stacking those effects is the risk that matters most h…”

About Dyer's Broom

What is Dyer's Broom?

Dyer's Broom
  • Skin irritation
  • Respiratory complaints
  • Gout
  • Lower back and pelvic pain
  • Digestive upset
  • As a natural yellow dye

Dyer's broom is a European flowering plant best known historically as a source of yellow textile dye, with some traditional medicinal uses. There is very little reliable human research to support any health benefit, and it contains compounds that can be toxic in larger amounts, so it should be used cautiously, if at all. Talk to your pharmacist or doctor before trying it.

Genista tinctoria · Fabaceae · Flowering tops, stems, and sometimes roots · Tea, dried herb, tincture, topical preparations

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

Dyer's Broom: dosing

There is no established standard dose for dyer's broom, and no reliable human research to guide safe amounts.

About Fenofibrate

What Is Fenofibrate Used For?

Brand names: Tricor, Fenofibrate, Lipidil Micro, Lipidil Supra, Antara, Lofibra, Triglide, Lipidil EZ

Fenofibrate is used alongside a cholesterol-lowering diet in adults to improve abnormal lipid levels. Tricor (tablet) and fenofibrate tablets are indicated to lower LDL cholesterol (bad cholesterol), total cholesterol, triglycerides, and apolipoprotein B, and to raise HDL cholesterol (good cholesterol) in adults with primary hypercholesterolemia (high cholesterol) or mixed dyslipidemia (mixed abnormal lipid levels). They are also used to treat severe hypertriglyceridemia (very high triglycerides).

Antara and Lipofen (capsules) are indicated to reduce triglyceride levels in adults with severe hypertriglyceridemia, and to lower LDL cholesterol in adults with primary hyperlipidemia when other recommended LDL-lowering therapies cannot be used. Fenofibrate has not been shown to reduce heart attacks or cardiovascular deaths in patients with type 2 diabetes.

Most-Reported Side Effects for Fenofibrate

Taking Dyer's Broom and Fenofibrate Together: Common Questions

Is it safe to take Dyer's Broom with Fenofibrate?

Do Dyer's Broom and Fenofibrate 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.

How was the Dyer's Broom and Fenofibrate combination checked?
Interactions in our licensed database are recorded against drug classes. Fenofibrate is filed under 3 classifications, and Dyer's Broom has documented interactions with 1 drug class — none of Fenofibrate'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 Dyer's Broom interact with any other medications?
Yes. Dyer's Broom has 29 documented drug interactions in our database — Fenofibrate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
