Hemp Agrimony and Ripretinib

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Ripretinib

Ripretinib falls under HEPATOTOXIC DRUGS — the group Hemp Agrimony interacts with.

Hemp agrimony contains hepatotoxic pyrrolizidine alkaloids (PA). Theoretically, using hemp agrimony with hepatotoxic drugs might have additive adverse effects on the liver. Some drugs that can adversely affect the liver include acetaminophen (Tylenol and others), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), fluconazole (Diflucan), itraconazole (Sporanox), erythromycin (Erythrocin, Ilosone, others), phenytoin (Dilantin), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and many others.
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 concern with combining hemp agrimony and Ripretinib (Qinlock). Hemp agrimony can contain pyrrolizidine alkaloids, natural compounds that may stress or damage the liver. Ripretinib itself can already raise liver enzymes and, less often, cause more serious liver problems. Putting two liver stressors together could add up and make liver injury more likely.

I want to be honest about the evidence here: this is a theoretical worry based on how these compounds behave, not something proven in studies of people taking both. Even so, since you're on a cancer therapy that your doctor is monitoring closely, I'd steer clear of internal hemp agrimony products and check with your oncologist or pharmacist before using anything new.

From our pharmacist’s overview on the Ripretinib page

“If you take ripretinib (Qinlock) for a GI stromal tumor, check this list carefully, since six of its 168 entries rate major. Ripretinib is cleared by the liver enzyme CYP3A4, and 121 of these ingredients can push its blood level up or drag it down through that pathway.”

About Hemp Agrimony

What is Hemp Agrimony?

Hemp Agrimony
  • Digestive complaints
  • Cold and flu symptoms
  • Respiratory conditions
  • Mild fever
  • Traditional 'tonic' or detox use

Hemp agrimony is a traditional European herb that has been used for digestion, colds, and as a general tonic, but there is very little reliable human research to support these uses. More importantly, the plant can contain pyrrolizidine alkaloids that may harm the liver, so most experts do not recommend taking it internally. Talk with your pharmacist or doctor before using any product that contains hemp agrimony.
