African Wild Potato and Probenecid

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

Why Are There 2 Interactions?

African Wild Potato interacts with whole categories of medication. Probenecid falls into 2 of those categories, so it can interact with African Wild Potato 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 3 (OAT3) SUBSTRATES

1 of 2

Why this applies to Probenecid

Probenecid falls under ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES — the group African Wild Potato interacts with.

In vitro evidence shows that African wild potato extract inhibits OAT3. This drug transport protein is involved in renal tubular uptake of some drugs from the blood and then elimination in the urine. Inhibition of this transporter decreases renal elimination and increases drug levels in the body. The clinical significance of this in humans is not known.
Some substrates of OAT3 include cephalosporins, famotidine (Pepcid), furosemide (Lasix), hydrochlorothiazide (HCTZ), methotrexate, NSAIDs, probenecid, ranitidine (Zantac).
Severity Moderate Likelihood Possible Evidence D

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 of it. Your kidneys use a little transporter called OAT3 to help move probenecid out of your blood and into your urine. Lab studies (just test-tube work, not people yet) suggest African Wild Potato may slow that transporter down. If that holds true in the body, your probenecid could clear a bit slower and build up to higher levels than expected.

What might that look like? Probenecid is generally well tolerated, but more of it can mean more stomach upset, nausea, headache, or dizziness. The honest truth is we don't have human data here, so this is more of a heads-up than a red alert. Before combining the two, run it past your pharmacist or doctor so they can keep an eye on how you're feeling.

ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES

2 of 2

Probenecid also falls under ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES.

In vitro research shows that African wild potato extract inhibits OAT1. This drug transport protein is involved in renal tubular uptake of some drugs from the blood and then elimination in the urine. Inhibition of this transporter decreases renal elimination and increases drug levels in the body. The clinical significance of this in humans is not known.
Some substrates of OAT1 include acyclovir (Zovirax), adefovir (Hepsera), cephalosporins, cidofovir (Vistide), cimetidine (Tagamet), ciprofloxacin (Cipro), furosemide (Lasix), hydrochlorothiazide (HCTZ), NSAIDs, oseltamivir (Tamiflu), pravastatin (Pravachol), probenecid, simvastatin (Zocor), and zidovudine (Retrovir).

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

Here's the simple version: your kidneys use a transporter called OAT1 to pull probenecid out of your blood and send it into your urine. In lab dish studies, African Wild Potato seemed to block that transporter. If that same thing happened in people, your body would clear probenecid more slowly, so levels could drift a bit higher than expected.

For probenecid, higher levels might mean more of its usual side effects, like upset stomach, headache, or flushing. I want to be honest though: this is only test-tube evidence, and we truly don't know if it matters in real people. Food amounts are one thing, but concentrated supplement doses are the bigger unknown. Please run it by your pharmacist or doctor before combining them.

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.
