Dusty Miller 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 Dusty Miller interacts with.

Theoretically, CYP3A4 inducers might increase the risk of adverse effects from the pyrrolizidine alkaloid (PA) constituents in dusty miller.
Dusty miller contains PAs. PAs are substrates of CYP3A4. Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites.
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 this pairing. Dusty Miller contains pyrrolizidine alkaloids, natural compounds that the liver enzyme CYP3A4 can turn into toxic byproducts that may harm the liver. Givinostat (Duvyzat) is thought to nudge that same enzyme to work faster (it acts as a CYP3A4 inducer). In theory, speeding up that enzyme could mean more of Dusty Miller's alkaloids get converted into those harmful forms.

I'll be honest, this concern is theoretical and comes only from lab and animal work, not from real patient studies, so I don't want to alarm you. But since givinostat already carries its own liver-related cautions, stacking an unproven and possibly liver-toxic plant on top isn't worth the gamble. Please check with your pharmacist or doctor before using any Dusty Miller product.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

“Givinostat (Duvyzat), taken for Duchenne muscular dystrophy, can affect the heart's electrical rhythm on its own, and several supplements here push in the same direction, so read this list with genuine care rather than a quick skim.

About Dusty Miller

What is Dusty Miller?

  • Cataracts (traditional eye use)
  • Eye irritation and inflammation
  • Wound healing (folk use)
  • Menstrual complaints (folk use)

Dusty Miller is a silvery ornamental plant that has been used in folk medicine, mainly as an eye remedy for cataracts and irritation. There is no reliable scientific evidence that it works, and the plant contains compounds (pyrrolizidine alkaloids) that can be toxic, so it is not considered safe for self-treatment. Talk to a pharmacist or doctor before using any product made from it.
