Drug & supplement interaction

Banderol + Probenecid

Probenecid brand names: Benemid, Benuryl, Probecid.

Moderate Interaction
The bottom line Moderate

Probenecid falls into 2 drug categories that Banderol can interact with; the most serious is rated moderate. Small lab studies have found that Banderol may inhibit OATP1B1 (Organic Anion Transporting Polypeptide 1B1), which is a membrane protein responsible for the uptake of various drugs, hormones, and other biologically active substances into the cells of the liver and other tissues.

Banderol and Probenecid

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Banderol interacts with whole categories of medication. Probenecid falls into 2 of those categories, so it can interact with Banderol in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES

1 of 2

Why this applies to Probenecid

Probenecid falls under ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES — the group Banderol interacts with.

Small lab studies have found that Banderol may inhibit OATP1B1 (Organic Anion Transporting Polypeptide 1B1), which is a membrane protein responsible for the uptake of various drugs, hormones, and other biologically active substances into the cells of the liver and other tissues. It is often referred to as a drug transporter. It is a member of the OATP family of transporters and is known to play a critical role in the pharmacokinetics of many drugs. When OATPs are inhibited, it can cause problems with the elimination of drugs and result in a sudden rise in the concentration of the drug in the bloodstream and the extent to which it is absorbed (AUC) for drugs that rely on these transporters. This can increase the likelihood of adverse side effects associated with the therapy.
Severity Moderate Likelihood Possible Evidence A

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.

Here's the gist with probenecid and Banderol. Probenecid is handled by transporter proteins that help shuttle it into and out of cells. Lab studies suggest Banderol may block one of these transporters (called OATP1B1). If that happens, your body could clear probenecid a bit more slowly, letting levels in your blood drift upward.

In plain terms, more probenecid hanging around could mean a higher chance of its usual side effects, like upset stomach, nausea, headache, or in rare cases a skin rash. The good news is this is theoretical, based only on small test-tube work, not real patient cases, so I wouldn't panic. Still, before mixing the two, check in with your pharmacist or doctor so they can keep an eye on how you're feeling.

Moderate

ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES

2 of 2

Probenecid also falls under ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES.

Small lab studies have found that Banderol may also inhibit OATP1B3 (Organic Anion Transporting Polypeptide 1B3), in addition to OATP1B1. If a drug is a substrate for both transporters, the risk of interaction with Banderol increases but the overall clinical significance is not well understood.
Severity Moderate Likelihood Possible Evidence A

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 short version on pairing Banderol with probenecid. Probenecid is moved around the body by certain transporter proteins, including ones in the OATP family. Some early test-tube research suggests Banderol may block a couple of these transporters. In theory, if Banderol slows the handling of probenecid, a bit more of the drug could linger in your system, which might nudge up side effects like nausea, upset stomach, headache, or flushing.

I want to be straight with you, though: this is based on small lab studies, not real-world human data, so the actual importance isn't clear. Probenecid isn't a prodrug, so we're not flipping any direction here. Since Banderol's benefits are also poorly proven, please loop in your pharmacist or doctor before combining 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.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

From our pharmacist’s overview on the Probenecid page

“Probenecid does its work through the kidneys, pulling uric acid out of the blood to control gout, and that is exactly why the 30 supplement and herbal interactions on file deserve genuine care rather than a quick skim. The three rated major strike where this drug is most vulnerable: two are herbs, Siberian cocklebur among them, that ca…”

About Banderol

What is Banderol?

Banderol
  • Lyme disease support
  • Antimicrobial
  • Antifungal
  • Immune support
  • Inflammation

Banderol is a Nutramedix-branded herbal extract made from the bark of the Amazonian tree Otoba parvifolia, most often promoted as part of alternative Lyme disease protocols. There is very little high-quality human research to support its use, so the evidence behind its benefits is weak and largely preliminary. Talk with your pharmacist or doctor before using it, and never use it to replace proven treatments.

About Probenecid

What Is Probenecid Used For?

Brand names: Benemid, Benuryl, Probecid

Probenecid tablets are used to treat hyperuricemia (high uric acid levels in the blood) associated with gout and gouty arthritis. By helping the kidneys remove more uric acid, it lowers uric acid levels over time and helps prevent painful gout attacks.

Probenecid tablets are also used alongside certain penicillin-type antibiotics — including penicillin, ampicillin, methicillin, oxacillin, cloxacillin, and nafcillin — to raise and sustain the antibiotic's level in the bloodstream, making the antibiotic work more effectively.
