Propolis and Leuprolide Acetate, Norethindrone Acetate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Leuprolide Acetate, Norethindrone Acetate

Leuprolide Acetate, Norethindrone Acetate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Propolis interacts with.

Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP3A4.
Some in vitro research shows that propolis extract can inhibit CYP3A4; however, other in vitro research shows that propolis has no effect on CYP3A4 activity. Furthermore, animal research shows that propolis extract does not significantly affect CYP3A4 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that might in inhibit CYP3A4 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.
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 with the Lupaneta Pack: the norethindrone part (a hormone) is processed by a liver enzyme called CYP3A4. In a test tube, some propolis compounds appear to slow that enzyme down, which could in theory let norethindrone build up a bit and bring more hormone-type side effects like spotting, breast tenderness, nausea, headaches, or mood changes. The leuprolide piece is an injection and isn't really affected by this.

But here's the honest part: this concern comes only from lab and animal studies, and it never actually panned out in living animals or in people, likely because propolis isn't well absorbed. So I wouldn't lose sleep over an occasional propolis lozenge. If you take concentrated propolis daily, just give your pharmacist or doctor a heads-up so they can keep an eye on things.

About Propolis

What is Propolis?

Propolis
  • Cold sores and herpes lesions (topical)
  • Sore throat and mouth sores
  • Wound and skin healing
  • Immune support
  • Oral and gum health

Propolis is a natural, resin-like substance made by bees that has antimicrobial and anti-inflammatory properties in lab studies. Early research suggests it may help with cold sores, mouth sores, and minor wounds, but high-quality evidence is limited for most uses. It is generally well tolerated, but allergic reactions can occur, especially in people allergic to bee products.
