Bee Venom and Sirolimus (albumin bound)

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Sirolimus (albumin bound)

Sirolimus (albumin bound) falls under IMMUNOSUPPRESSANTS — the group Bee Venom interacts with.

Bee venom might stimulate immune system activity.Theoretically, bee venom might interfere with immunosuppressant therapy. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), corticosteroids (glucocorticoids), and others.
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 explains PharmD, Clinical Pharmacist

Here's the thinking behind this one. Your Fyarro (albumin-bound sirolimus) is doing a specific job: it quiets down the signals that tell those tumor cells to grow, and it dampens immune activity along the way. Bee venom, on the other hand, may rev the immune system up. So in theory they pull in opposite directions, and the worry is that bee venom could blunt some of the benefit you're getting from your treatment.

I want to be honest about the evidence here, though. This is a theoretical concern based on lab work, not real patient cases, so please don't be alarmed. There's also a real, separate risk: bee venom can trigger serious allergic reactions. Since this medicine is treating cancer, I'd skip bee venom unless you've cleared it with your oncologist or pharmacist first.

About Bee Venom

What is Bee Venom?

Bee Venom
  • Joint pain and arthritis
  • Muscle and nerve pain
  • Bee sting allergy desensitization
  • Skin and cosmetic uses
  • Multiple sclerosis (traditional/alternative use)

Bee venom is a complex mixture of proteins and other compounds taken from honeybees and used in traditional medicine for pain and inflammation, and in conventional medicine for allergy shots to prevent severe sting reactions. Outside of supervised allergy treatment, strong evidence for its benefits is lacking, and it can cause serious allergic reactions, so it should only be used under medical supervision.
