African Wild Potato and Oxaprozin

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. Oxaprozin 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 Oxaprozin

Oxaprozin 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 for Oxaprozin (Daypro): your kidneys help clear this NSAID out of your body, partly using a transporter called OAT3. In lab tests, African Wild Potato appears to block OAT3. If that same blocking happened in people, your body might hold onto more oxaprozin, which could nudge up the usual NSAID side effects like stomach upset, heartburn, fluid retention, higher blood pressure, or extra strain on the kidneys.

I want to be honest with you, though: this is based only on test-tube and animal work, so we really don't know if it matters in real life. It's worth a quick chat with your pharmacist or doctor before combining them, especially if you have kidney or heart concerns.

ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES

2 of 2

Oxaprozin 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).
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 simple version: your kidneys use a little doorway called OAT1 to push certain medicines out into your urine. Lab studies suggest African Wild Potato may partly block that doorway. Since oxaprozin (Daypro) can be cleared this way, blocking it could let the drug linger longer and build up a bit in your body.

If that happened, you might notice more of oxaprozin's usual side effects, things like stomach upset, heartburn, fluid retention, higher blood pressure, or kidney strain. The honest truth, though, is that this is based only on test-tube research, so we don't know if it really matters in people. To be safe, mention African Wild Potato to your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Oxaprozin page

“I would put oxaprozin (Daypro), a long-acting NSAID prescribed for arthritis pain, in the read-carefully category. The interactions that concern me most pile onto the drug's own weak spots: alcohol, meaning the beer and wine entries below, raises the odds of stomach bleeding on any NSAID, and several kidney-stressing herbs can deepen t…”
