Puravive and rosiglitazone, glimepiride

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

Why Are There 2 Interactions?

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

Moderate

Cytochrome P450 2C9 (Cyp2C9) Substrates

1 of 2

Why this applies to rosiglitazone, glimepiride

rosiglitazone, glimepiride falls under Cytochrome P450 2C9 (Cyp2C9) Substrates — the group Puravive interacts with.

Puravive contains quercetin, which has been shown in studies to mildly inhibit the CYP2C9 metabolizing enzyme. This inhibition could potentially increase the risk of side effects from drugs. A small clinical trial with healthy volunteers found that taking 500 mg of quercetin twice daily for 10 days before using diclofenac, a drug metabolized by CYP2C9, increased diclofenac plasma levels by 75% and extended its half-life by 32.5% (source: https://pubmed.ncbi.nlm.nih.gov/29168292/). Combining quercetin with drugs metabolized by CYP2C9 could increase the risk of side effects, so caution is advised.
Severity Moderate 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 explains PharmD, Clinical Pharmacist

Avandaryl combines two diabetes medicines: rosiglitazone and glimepiride. Both lean on the liver enzyme CYP2C9 to be cleared from your body. Puravive contains quercetin, which can mildly slow that enzyme down. When the enzyme works slower, these medicines can hang around longer and build up a bit, which makes their blood-sugar-lowering effect a little stronger than expected.

For glimepiride especially, that could mean a higher chance of low blood sugar (shakiness, sweating, dizziness, confusion, or feeling weak). Keep in mind the evidence here is modest, drawn from a small quercetin study using a different drug, so the real-world effect may be minor. Still, please check with your pharmacist or doctor before adding Puravive, and watch your glucose readings if you do.

Minor

Antidiabetes Drugs

2 of 2

rosiglitazone, glimepiride also falls under Antidiabetes Drugs.

Puravive contains Panax ginseng. Clinical studies indicate that Panax ginseng may lower blood sugar levels. One study (https://pubmed.ncbi.nlm.nih.gov/25015735/) found that supplementation with Panax ginseng led to a significant decrease in post-meal glucose levels and an increase in post-meal insulin levels compared to a placebo. If you are taking medications that lower blood sugar, it's important to monitor your blood glucose levels closely when using Panax ginseng.
Severity Minor Likelihood Possible Evidence B

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 thing to keep in mind with Avandaryl (rosiglitazone plus glimepiride): it already works to bring your blood sugar down, and Puravive contains Panax ginseng, which some studies suggest can nudge blood sugar a little lower on its own. Stacking the two could add up, so your readings might drop more than expected.

The glimepiride part is the bigger player here, since that type of medicine can cause true low blood sugar (shakiness, sweating, dizziness, or feeling foggy). The evidence for ginseng's effect is modest and the overall risk is rated minor, so this isn't an alarm bell, just a good reason to check your glucose more often if you try Puravive. Loop in your pharmacist or doctor before combining them.

  • 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.

From our pharmacist’s overview on the rosiglitazone, glimepiride page

“Siberian cocklebur worries me most on this page. Its seeds have caused severe, worsening drops in blood sugar in people, and rosiglitazone with glimepiride (Avandaryl) already pulls glucose down through two separate mechanisms, so these pairings deserve real vigilance.”

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.
