Moderate Interaction
Medically reviewed by · Updated February 2024
The bottom line Moderate

Erythromycin Gluceptate falls into 3 drug categories that Puravive can interact with; the most serious is rated moderate. 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.

Puravive and Erythromycin Gluceptate

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. Erythromycin Gluceptate 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

Qt Interval-Prolonging Drugs

1 of 3

Why this applies to Erythromycin Gluceptate

Erythromycin Gluceptate falls under Qt Interval-Prolonging Drugs — the group Puravive interacts with.

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/).
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.

Here's the thing to know about combining Puravive with erythromycin. One ingredient in Puravive, Panax ginseng, may slightly affect your heart's electrical timing (what doctors call the QT interval). Erythromycin is already well known for stretching that same interval on its own. When two things nudge the QT in the same direction, the small risk of an abnormal heart rhythm can add up.

Now, the evidence here is mixed and on the weaker side. Some short studies showed ginseng lengthened the QT a bit, while longer use showed no change, so this isn't a strong, proven danger. Still, since erythromycin alone carries this risk, it's worth mentioning. If you've got a heart condition, take other QT-affecting drugs, or feel dizzy or have a fluttering heartbeat, check in with your pharmacist or doctor before pairing these.

Cytochrome P450 3A4 (Cyp3A4) Substrates

2 of 3

Erythromycin Gluceptate also falls under Cytochrome P450 3A4 (Cyp3A4) Substrates.

Puravive contains Panax ginseng. Panax ginseng has the potential to affect the breakdown of drugs that are metabolized by an enzyme called CYP3A4. One example of such a drug is imatinib. There was a case where imatinib was thought to have caused liver damage, and it was believed that this might have been due to Panax ginseng inhibiting CYP3A4, which is involved in imatinib's metabolism (https://pubmed.ncbi.nlm.nih.gov/20332334/). On the other hand, Panax ginseng has been found to increase the breakdown of another drug called midazolam, which is also metabolized by CYP3A4 (https://pubmed.ncbi.nlm.nih.gov/21646440/), suggesting Panax ginseng induces CYP3A4 in some cases (i.e., makes more potent). Given these contradictory findings, it is important to use Panax ginseng cautiously if you are taking medications that are metabolized by CYP3A4, as the interaction between Panax ginseng and these drugs is not fully understood.
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 situation with Puravive and erythromycin. Puravive contains Panax ginseng, and ginseng can nudge the CYP3A4 enzyme that helps process erythromycin. The tricky part is that studies disagree: in some cases ginseng seems to slow this enzyme (which could let erythromycin build up a bit), and in others it seems to speed it up (which could weaken the antibiotic). So we honestly can't predict which way it would go for you.

The good news is this is rated a minor, possible interaction based on weak evidence, so it's not something to panic over. Still, if erythromycin built up, you might notice more stomach upset, nausea, or cramping. To be safe, check with your pharmacist or doctor before pairing the two.

P-Glycoprotein Substrates

3 of 3

Erythromycin Gluceptate also falls under P-Glycoprotein Substrates.

Puravive contains quercetin. Theoretically, concurrent use of quercetin and P-glycoprotein substrates might alter the effects and adverse effects of the drugs. There is preliminary evidence suggesting that quercetin inhibits the P-glycoprotein efflux pump in the gastrointestinal tract. This inhibition could potentially increase the bioavailability and serum levels of drugs transported by this pump. For example, a small study in healthy volunteers found that pretreatment with quercetin increased bioavailability and plasma levels following a single dose of cyclosporine (Neoral, Sandimmune) (source: https://pubmed.ncbi.nlm.nih.gov/15581264/). However, other small studies have shown that quercetin might decrease the absorption of talinolol, another substrate of the gastrointestinal P-glycoprotein efflux pump. Interestingly, several days of quercetin treatment did not significantly affect the pharmacokinetics of saquinavir (Invirase) in another small study (source: https://pubmed.ncbi.nlm.nih.gov/16945047/). The reason for these discrepancies is not entirely clear. Until more is known, it is advisable to use quercetin cautiously in combination with P-glycoprotein substrates.
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 short version: Puravive contains quercetin, which in some lab and small human studies seems to block a gut pump called P-glycoprotein. Erythromycin happens to be moved around by that same pump. In theory, slowing the pump could let a bit more erythromycin into your bloodstream, which might nudge up its usual side effects like nausea, stomach cramping, diarrhea, or, less commonly, heart rhythm changes (a longer QT interval).

I want to be honest, though: this is mostly theoretical. The evidence is weak and even mixed, with quercetin raising some drugs and lowering others. Overall it's rated a minor interaction. Still, since erythromycin can affect heart rhythm, it's worth a quick chat with your pharmacist or doctor before combining them, rather than guessing.

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.
