Puravive and Brincidofovir

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

Minor

Organic Anion-Transporting Polypeptide Substrates (Oatp)

Why this applies to Brincidofovir

Brincidofovir falls under Organic Anion-Transporting Polypeptide Substrates (Oatp) — the group Puravive interacts with.

Puravive contains quercetin. The simultaneous use of quercetin and OATP substrates (the drug in question in this interaction is reported to be an OATP substrate) may theoretically enhance their effects and adverse effects. In vitro studies indicate that quercetin can inhibit the uptake of estrone-3-sulfate and pravastatin, which are transported by OATP 1B1. Clinical research in healthy males demonstrates that co-administration of quercetin and pravastatin increases the area under the curve (AUC) of pravastatin by 24%, prolongs its half-life by 14%, and reduces its apparent clearance by 18% (source: https://pubmed.ncbi.nlm.nih.gov/22114872/). Overall, quercetin may increase the risk of side effects of drugs that are OATP substrates when taken together.
Severity Minor 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: Puravive contains quercetin, a plant compound that can gently block a transporter called OATP, which helps move certain drugs into the liver. Brincidofovir (Tembexa), the antiviral you're asking about, is moved partly by that same transporter. So in theory, quercetin could slow its clearance and let a bit more linger in your body, which might nudge up side effects like diarrhea, nausea, belly pain, or liver enzyme changes.

That said, I want to keep this in perspective. The evidence here is theoretical and weak, mostly from lab work and a small study on a different drug where the effect was modest. I wouldn't lose sleep over it, but since Brincidofovir is a serious medicine, please run this combo by your pharmacist or doctor before adding Puravive.

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.

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.

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.
