Hemp Agrimony and Teplizumab-mzwv

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Teplizumab-mzwv

Teplizumab-mzwv 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 pairing hemp agrimony and Tzield (teplizumab). This isn't about how your body breaks down the drug. Hemp agrimony can contain pyrrolizidine alkaloids, natural compounds that may stress the liver. Teplizumab, the infused medicine used to delay type 1 diabetes, can also raise liver enzymes in some people. Stacking two liver stressors together could, in theory, add up and put more strain on your liver.

I'll be honest that this is a theoretical worry based on how these things work, not proven harm. Still, since hemp agrimony's liver risk is real enough that many experts advise against taking it at all, I'd skip it here. Please check with your doctor or pharmacist first, and watch for yellowing skin, dark urine, or belly pain.

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.
