Puravive and Carvedilol

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Puravive interacts with whole categories of medication. Carvedilol falls into 3 of those categories, so it can interact with Puravive in 3 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 3

Why this applies to Carvedilol

Carvedilol 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

Here's the gist: one of the ingredients in Puravive, quercetin, can gently slow down a liver enzyme called CYP2C9. Your body uses that enzyme (along with others) to help clear carvedilol. If it works a little slower, carvedilol could build up more than usual, which means a stronger beta-blocker effect than you bargained for.

In real life, that might show up as a heart rate that runs too slow, lightheadedness or dizziness, feeling unusually tired, or blood pressure dropping low enough to make you woozy when you stand up. The evidence here is on the weaker side and based mostly on a small study with a different drug, so this isn't a sure thing. Still, since carvedilol affects your heart, it's worth a quick chat with your pharmacist or doctor before adding Puravive. Please don't change your dose on your own.

Cytochrome P450 2D6 (Cyp2D6) Substrates

2 of 3

Carvedilol also falls under Cytochrome P450 2D6 (Cyp2D6) Substrates.

Puravive contains Panax ginseng. Some research suggests that Panax ginseng might slow down the activity of an enzyme called CYP2D6 by about 6%. This enzyme plays a role in breaking down drugs in our system. One study (https://pubmed.ncbi.nlm.nih.gov/32557706/) found that Panax ginseng slows down the breakdown of dextromethorphan, a drug that is processed by CYP2D6, but only to a small extent. It is important to note that not all studies agree on these effects, and some suggest that Panax ginseng might not have a significant impact on CYP2D6 at all. Nevertheless, it's important to be cautious if you're taking medications that are processed by CYP2D6 and consider discussing it with your healthcare provider.
Severity Minor 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. Your body relies on an enzyme called CYP2D6 to help clear carvedilol. Puravive contains Panax ginseng, which might slow that enzyme down a little. If carvedilol is cleared more slowly, slightly more can hang around in your system, which in theory could nudge its effects up a bit. With a beta-blocker like this, that mostly shows up as a slower heart rate, lower blood pressure, lightheadedness, or feeling unusually tired.

I don't want to overstate this, though. The research points to only a small change (around 6%), the evidence is weak, and some studies show no real effect at all. For most people this is unlikely to cause trouble. Still, if you notice dizziness or a slow pulse, or you have heart failure, please check with your pharmacist or doctor first.

Antihypertensive Drugs

3 of 3

Carvedilol also falls under Antihypertensive Drugs.

Puravive contains quercetin, which has been found to slightly reduce blood pressure in individuals with mild hypertension (https://pubmed.ncbi.nlm.nih.gov/17951477/). There is a theoretical possibility that it could enhance the blood pressure-lowering effects of antihypertensive medications.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. One ingredient in Puravive, quercetin, has shown a mild blood-pressure-lowering effect in a small study of people with mild hypertension. Since carvedilol (Coreg) already works to relax your blood vessels and lower your blood pressure and heart rate, stacking the two could, in theory, add up to a slightly bigger drop than expected.

If that happened, you might feel lightheaded, dizzy, or unusually tired, especially when standing up quickly. To be honest, this is a theoretical, minor concern based on weak evidence, not something proven to cause trouble. Still, since you're on carvedilol for your heart, I'd run Puravive past your pharmacist or doctor first, and watch how you feel if you do start it.

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.

About Carvedilol

What Is Carvedilol Used For?

Brand names: Coreg, Coreg CR

Carvedilol is used to treat three main conditions: mild-to-severe chronic heart failure, high blood pressure (hypertension), and reduced heart pumping function (left ventricular dysfunction) in people who have survived a heart attack. For heart failure, it is usually prescribed alongside other medications such as diuretics, ACE inhibitors, and digitalis to help people live longer and reduce the chance of hospital stays.

For people who have had a heart attack and whose heart is not pumping as well as it should, carvedilol is used to lower the risk of dying from heart-related causes. For high blood pressure, it can be used on its own or combined with other blood pressure medicines.
