Drug & supplement interaction

Banderol + Cefotaxime

Cefotaxime brand name: Claforan.

Moderate Interaction
Medically reviewed by · Updated February 2023
The bottom line Moderate

Cefotaxime 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 Cefotaxime

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. Cefotaxime 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 Cefotaxime

Cefotaxime 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for cefotaxime (Claforan): it's an injectable cephalosporin antibiotic that your kidneys and liver help move out of your body using transporter proteins. Banderol has shown in test-tube studies that it may block one of these transporters. In theory, if that transporter is slowed down, cefotaxime could leave your system a little more slowly and build up a bit higher than expected. Cefotaxime is not a prodrug, so more drug hanging around mostly means a higher chance of side effects like stomach upset, diarrhea, or irritation at the injection site.

I want to be honest about how soft this evidence is, since it comes from lab work, not from people. Cefotaxime is also given and monitored by clinicians in a medical setting, so just let your care team know if you're using Banderol.

ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES

2 of 2

Cefotaxime 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 simple version for Cefotaxime (Claforan), the injectable antibiotic you'd usually get in a hospital or clinic. Banderol has been shown in test-tube studies to block certain transporter proteins (the OATP family) that help move some drugs through the body. Since your kidneys also clear cefotaxime using transporters, the theory is that Banderol could slow how fast the drug leaves you, letting a bit more linger. In plain terms, that might mean slightly stronger drug levels and a touch more chance of side effects like stomach upset, diarrhea, or irritation where it's injected.

That said, this is based on lab work, not real patient studies, so the true effect in people isn't clear. Because cefotaxime is given by a medical team, just tell them you're using Banderol so they can keep an eye on things.

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.

This page covers Banderol only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefotaxime page lists 45 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate), Aristolochia (moderate) and Bacillus Coagulans (moderate).

By severity: 2 major · 39 moderate · 4 minor.

From our pharmacist’s overview on the Cefotaxime page

“The two entries worth understanding first on this cefotaxime (Claforan) list are Siberian cocklebur and asarabacca. Both can damage the kidneys on their own, and stacking that on an injectable antibiotic often given to people who are already quite sick is a risk I would not take lightly.”

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 Cefotaxime Injection

What Is Cefotaxime Injection Used For?

Brand name: Claforan

Cefotaxime Injection is used to treat serious bacterial infections in many parts of the body — including the lungs, urinary tract, skin, bones and joints, abdomen, reproductive organs, and central nervous system (such as meningitis). It also treats bloodstream infections (septicemia) and certain sexually transmitted infections, including gonorrhea.

It is also given before certain surgeries — such as abdominal or vaginal hysterectomy, gastrointestinal surgery, and cesarean section — to reduce the risk of postoperative infection. Because cefotaxime has no activity against Chlamydia trachomatis, an additional antibiotic must be added when that organism is a suspected cause of pelvic inflammatory disease.
