Golden Ragwort and tipranavir

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

Why this applies to tipranavir

tipranavir falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Golden Ragwort interacts with.

Theoretically, CYP3A4 inducers might increase the risk of adverse effects from the pyrrolizidine alkaloid (PA) constituents in golden ragwort.
Golden ragwort 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 the worry runs in an unusual direction. It is not that golden ragwort changes your tipranavir (Aptivus) levels. Instead, tipranavir can speed up a liver enzyme called CYP3A4, and that same enzyme is what turns the pyrrolizidine alkaloids in golden ragwort into harmful, liver-damaging byproducts. So in theory, taking tipranavir could make this plant more toxic to your liver, not less.

I want to be honest about the evidence: this is theoretical and comes from lab and animal work, not from people. But here is my real bottom line, golden ragwort already isn't considered safe to swallow because of those liver toxins, with or without any medication. I would steer clear of it entirely and run any herbal product past your pharmacist or HIV provider first.

About Golden Ragwort

What is Golden Ragwort?

  • Menstrual complaints
  • Easing childbirth (traditional)
  • Urinary discomfort
  • Sore throat (folk use)

Golden Ragwort is a flowering plant once used in traditional and folk medicine, mainly for menstrual and female reproductive complaints. It contains pyrrolizidine alkaloids that can cause serious liver damage, so it is not considered safe for internal use, and modern herbalists generally avoid it.

About Tipranavir

What Is Tipranavir Used For?

Brand name: Aptivus

Aptivus (tipranavir) is used to treat HIV-1 infection in adults and in pediatric patients weighing at least 36 kg (about 79 lbs). It is specifically for people who have already tried other HIV treatments and whose virus has become resistant to more than one protease inhibitor. It is always taken together with a low dose of ritonavir and with other HIV medications.

Aptivus is not recommended for people who have never taken HIV treatment before (treatment-naïve patients). Using tipranavir alongside additional active HIV drugs improves the chances of it working well.
