Puravive and Flurbiprofen

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

Moderate

Cytochrome P450 2C9 (Cyp2C9) Substrates

Why this applies to Flurbiprofen

Flurbiprofen falls under Cytochrome P450 2C9 (Cyp2C9) Substrates — the group Puravive interacts with.

Puravive contains quercetin, which has been shown in studies to mildly inhibit the CYP2C9 metabolizing enzyme. This inhibition could potentially increase the risk of side effects from drugs. A small clinical trial with healthy volunteers found that taking 500 mg of quercetin twice daily for 10 days before using diclofenac, a drug metabolized by CYP2C9, increased diclofenac plasma levels by 75% and extended its half-life by 32.5% (source: https://pubmed.ncbi.nlm.nih.gov/29168292/). Combining quercetin with drugs metabolized by CYP2C9 could increase the risk of side effects, so caution is advised.
Severity Moderate Likelihood Possible Evidence C

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 gist: Flurbiprofen is an NSAID that your liver clears using an enzyme called CYP2C9. Puravive contains quercetin, which can mildly slow that same enzyme down. When the enzyme works slower, flurbiprofen can hang around longer and build up a bit, which may nudge up its typical side effects, things like stomach upset or pain, heartburn, a higher chance of stomach bleeding, fluid retention, or strain on the kidneys.

The evidence here is modest. It comes from a small study using a related NSAID (diclofenac), not flurbiprofen itself, so the effect is plausible but not certain. Food-level amounts of quercetin are unlikely to matter much, but concentrated supplement doses could. Please check with your pharmacist or doctor before pairing them.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • 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.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

From our pharmacist’s overview on the Flurbiprofen page

“Anyone taking flurbiprofen (Ansaid), an NSAID pain reliever, should treat this list with genuine care, starting with the entries that pile onto the drug's own weak points, the stomach lining and the kidneys. Drinking alcohol, beer and wine both make the list, raises the chance of stomach bleeding beyond what any NSAID already carries,…”

About Puravive

What is Puravive?

Puravive
  • Weight management
  • Metabolism support
  • Energy levels
  • General wellness
  • Stress and brain health

Puravive is a branded, multi-ingredient capsule marketed mainly for weight loss by claiming to boost brown fat activity, but there is no published, independent clinical research showing the product itself works for this purpose. Some individual ingredients have been studied in laboratory or small human studies, but those results do not prove the finished blend is safe or effective. Talk to a pharmacist or doctor before trying it, especially if you have health conditions or take medications.
