Picrorhiza and Pomalidomide

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Pomalidomide

Pomalidomide falls under IMMUNOSUPPRESSANTS — the group Picrorhiza interacts with.

Picrorhiza seems to have immunostimulating activity. Theoretically, picrorhiza may 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), and other corticosteroids (glucocorticoids).
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 thing to know about pairing Picrorhiza with Pomalyst (pomalidomide). This herb appears to gently rev up the immune system in lab studies. Pomalidomide is a bit different from a classic immune suppressant, but it does work in part by shaping how your immune system behaves to fight myeloma cells. The worry, in theory, is that an immune-stimulating herb could tug against your cancer treatment's intended effect.

I want to be honest about how soft this evidence is. It comes only from test tube and animal work, not real patients, so we truly don't know if it matters in people. Still, with a serious cancer drug, I'd rather you not gamble. Please run Picrorhiza by your oncologist or pharmacist before adding it.

About Pomalidomide

What Is Pomalidomide Used For?

Brand name: Pomalyst

Pomalidomide capsules are used in adults with multiple myeloma (a blood cancer affecting plasma cells) who have already tried at least two prior treatments — including lenalidomide and a proteasome inhibitor — and whose disease has continued to progress. It is given in combination with dexamethasone for this use.

Pomalidomide capsules are also used to treat Kaposi sarcoma (KS) — a cancer that can cause lesions on the skin and in internal organs — both in adults with AIDS-related KS after antiretroviral therapy has stopped working, and in adults with KS who are HIV-negative. The KS indication was approved based on response rate; ongoing studies are confirming long-term benefit.
