Chrysin and Dolutegravir, Rilpivirine

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

Minor

GLUCURONIDATED DRUGS

Why this applies to Dolutegravir, Rilpivirine

Dolutegravir, Rilpivirine falls under GLUCURONIDATED DRUGS — the group Chrysin interacts with.

Theoretically, chrysin might increase the clearance of drugs that are UGT1A1 substrates, thereby reducing their effectiveness.
In vitro research suggests that chrysin might induce UDP-glucuronosyltransferase 1A1 (UGT1A1).
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Juluca (dolutegravir and rilpivirine). Dolutegravir is partly cleared by a liver process called glucuronidation through an enzyme known as UGT1A1. In lab dish studies only, chrysin appeared to speed up that enzyme. If that happened in real life, your body could clear dolutegravir a little faster, which in theory might lower its blood levels and make your HIV treatment less reliable. With HIV medicines, keeping levels steady really matters, since drops can let the virus rebound or build resistance.

That said, this is only a theoretical, test-tube finding, and the body absorbs very little chrysin, so a real problem is unlikely. Still, before adding chrysin, please run it by your pharmacist or HIV provider first.

From our pharmacist’s overview on the Dolutegravir, Rilpivirine page

“Juluca combines dolutegravir and rilpivirine into a single daily HIV pill, and staying suppressed depends on that pill working at full strength every day, which is why this list calls for real vigilance. Most of the 159 interacting supplements and herbs change how the body handles the medication, some raising its levels and others lowe…”

About Chrysin

What is Chrysin?

  • Bodybuilding and testosterone support
  • Anxiety and stress
  • Anti-inflammatory
  • Antioxidant support
  • Prostate health

Chrysin is a plant flavonoid sold mainly as a bodybuilding supplement claimed to raise testosterone or block estrogen, but human studies have not shown these benefits, largely because the body absorbs very little of it. Evidence for its other proposed uses is mostly limited to laboratory and animal research, so its real-world value is unclear. Talk with your pharmacist or doctor before using it.
