Puravive and Fluoxetine

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. Fluoxetine 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 Fluoxetine

Fluoxetine 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: Puravive contains quercetin, which can gently slow down a liver enzyme called CYP2C9. Fluoxetine is partly handled by that same enzyme (along with a few others). So in theory, taking the two together could let a bit more fluoxetine linger in your system, nudging up its effects and side effects rather than weakening it. Fluoxetine is not a prodrug, so more enzyme blocking means more active drug, not less.

For fluoxetine, that might look like more jitteriness, trouble sleeping, nausea, headache, or restlessness. Honestly though, this is a mild and fairly theoretical interaction, the kind studied with quercetin and other drugs, not fluoxetine directly. I wouldn't panic, but do check with your pharmacist or doctor before combining them.

Moderate

Qt Interval-Prolonging Drugs

2 of 3

Fluoxetine also falls under Qt Interval-Prolonging Drugs.

Puravive contains Panax ginseng. Panax ginseng is thought to have an additive effect with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias. However, research findings on this matter are conflicting. Clinical studies indicate that short-term use of Panax ginseng can increase the QT interval (source: https://pubmed.ncbi.nlm.nih.gov/27240158/). However, no changes in the QT interval have been observed with prolonged use (source: https://pubmed.ncbi.nlm.nih.gov/11978148/).

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing Puravive with fluoxetine (Prozac). Puravive contains Panax ginseng, and fluoxetine is one of those medications that can gently stretch out the heart's electrical rhythm, what doctors call the QT interval. Stacking the two together could, in theory, add up and slightly raise the chance of an irregular heartbeat.

I want to be honest about how shaky this evidence is. Studies on ginseng and QT actually conflict, with short-term use nudging it up and longer-term use showing no real change. So for most healthy folks this is a low-level, mostly theoretical concern. That said, if you have a known heart rhythm problem, take other QT-affecting drugs, or feel dizzy, faint, or notice palpitations, loop in your pharmacist or doctor before combining them.

Minor

Cytochrome P450 2D6 (Cyp2D6) Substrates

3 of 3

Fluoxetine 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 for Prozac (fluoxetine). One ingredient in Puravive, Panax ginseng, may slightly slow down a liver enzyme called CYP2D6, which is one of the pathways your body uses to clear fluoxetine. Fluoxetine is an active drug (not a prodrug that needs switching on), so slowing its breakdown could let a little more linger in your system. In theory that might nudge up familiar side effects like nausea, trouble sleeping, jitteriness, or headache.

That said, the evidence here is weak. The enzyme slowdown seen in studies was tiny (around 6%), studies don't all agree, and this is rated a minor, possible interaction. For most people it won't cause noticeable problems. Still, if you're considering Puravive, it's worth a quick chat with your pharmacist or doctor first.

  • 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.

From our pharmacist’s overview on the Fluoxetine page

“Grapefruit is the surprise at the top of fluoxetine's (Prozac) supplement list. In large amounts it can stretch the QT interval, the electrical pause between heartbeats, and fluoxetine, a widely prescribed antidepressant, can do the same, raising the odds of a dangerous rhythm.”

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.
