Syrian Rue and Fenofibrate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

HEPATOTOXIC DRUGS

Why this applies to Fenofibrate

Fenofibrate falls under HEPATOTOXIC DRUGS — the group Syrian Rue interacts with.

Theoretically, high doses of Syrian rue might increase the risk of liver damage when taken with hepatotoxic drugs.
Cases of hepatotoxicity and hepatic failure have been reported in patients who ingested a large quantity (up to 100 grams) of Syrian rue seeds.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing Syrian Rue with fenofibrate. This isn't about one speeding up or slowing down the other. The concern is that both can be hard on your liver. Fenofibrate already carries a known risk of liver irritation, which is why your doctor checks your liver enzymes with blood tests now and then. Large amounts of Syrian Rue seeds (we're talking concentrated, heavy doses, even up to 100 grams) have been linked to liver injury and, rarely, liver failure.

Stacking two liver stressors together could, in theory, raise that risk. I'll be honest with you: this is based on how these things behave, not on solid human studies combining them. Watch for yellowing skin or eyes, dark urine, belly pain, or unusual tiredness, and check with your pharmacist or doctor before mixing the two.

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 Syrian Rue

What is Syrian Rue?

  • Traditional remedy for digestive complaints
  • Used as a sedative or for mood
  • Antimicrobial and antiparasitic folk use
  • Used as a dye and incense
  • Recreational psychoactive use

Syrian Rue (Peganum harmala) is a traditional plant whose seeds contain potent compounds called harmala alkaloids, including MAO-inhibiting harmine and harmaline. There is little reliable human evidence that it safely treats any condition, and it carries real risks of toxicity, so it is not recommended for self-treatment. Talk to a pharmacist or doctor before considering it.

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.
