Groundsel and givinostat

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to givinostat

givinostat falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Groundsel interacts with.

Theoretically, taking CYP3A4 inducers with groundsel might increase the risk of pyrrolizidine alkaloid toxicity, such as hepatotoxicity.
Pyrrolizidine alkaloids, constituents of groundsel, are converted to toxic metabolites by CYP3A4.
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 understand about mixing groundsel with givinostat (Duvyzat). Givinostat is one of those medicines that can rev up a liver enzyme called CYP3A4. Normally that just changes how other drugs are handled, but groundsel is different. It contains pyrrolizidine alkaloids, and CYP3A4 is exactly the enzyme that turns those plant compounds into toxic byproducts that harm the liver.

So by speeding up that enzyme, givinostat could theoretically make groundsel more damaging to your liver, not less. I'll be honest with you: this concern comes from lab and animal work, not real patients, so it's more of a caution than a proven danger. But since we already advise against taking groundsel at all, and givinostat itself can affect the liver and blood counts, I'd steer clear and check with your doctor or pharmacist first.

About Groundsel

What is Groundsel?

  • Menstrual complaints
  • Digestive upset
  • Minor wounds (topical)
  • Sore gums or mouth
  • Mild aches

Groundsel is a common weed traditionally used as a folk remedy, but it contains pyrrolizidine alkaloids that can cause serious liver damage. There is no reliable evidence that it works for any condition, and most health authorities consider it unsafe to take internally. We do not recommend using it.
