Tinospora Cordifolia and Palbociclib

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Palbociclib

Palbociclib falls under IMMUNOSUPPRESSANTS — the group Tinospora Cordifolia interacts with.

Theoretically, Tinospora cordifolia might reduce the effectiveness of immunosuppressants.
In vitro and animal research shows that Tinospora cordifolia has immunostimulant effects.
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 idea behind this pairing. Giloy (Tinospora cordifolia) has shown immune-stimulating activity in lab and animal studies, meaning it may rev up the immune system. Palbociclib (Ibrance) isn't a classic immunosuppressant, but it does dampen certain cells and is often grouped that way in interaction databases. So in theory, an herb that boosts immune activity could work against what your cancer treatment is doing.

I want to be straight with you: this concern is theoretical only, based on how the plant behaves in the lab, not on real patient cases with Palbociclib. There's also a separate worry, since Giloy has been linked to liver injury, and Palbociclib already requires liver monitoring. Please don't add this supplement without first checking with your oncologist or pharmacist.

About Palbociclib

What Is Palbociclib Used For?

Brand name: Ibrance

Palbociclib (brand name Ibrance) is used to treat adults with hormone receptor (HR)-positive, HER2-negative advanced or metastatic breast cancer. It is always given in combination with other medicines — either an aromatase inhibitor as a first hormonal treatment, or with fulvestrant after the cancer has progressed on prior hormonal therapy. It is also used with inavolisib and fulvestrant for a specific subtype (PIK3CA-mutated, endocrine-resistant) of this cancer confirmed by an FDA-authorized test.

Ibrance is also approved in combination with trastuzumab (with or without pertuzumab) and endocrine therapy for maintenance treatment of adults with HR-positive, HER2-positive locally advanced or metastatic breast cancer, following initial induction treatment.
