Greater Celandine and Basiliximab

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Basiliximab

Basiliximab falls under IMMUNOSUPPRESSANTS — the group Greater Celandine interacts with.

Preliminary clinical research suggests that taking a specific semi-synthetic derivative of the greater celandine constituent chelidonine (Ukrain; not available in North America) might stimulate immune responses in cancer patients. Theoretically, taking greater celandine might decrease the effects of immunosuppressive 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 concern with mixing greater celandine and Simulect (basiliximab). Basiliximab is given to quiet down your immune system right after a kidney transplant, so your body doesn't attack the new organ. Greater celandine appears to push in the opposite direction. Some early research on a celandine-derived compound suggests it may stimulate the immune system. In theory, that could work against basiliximab and weaken the protection you need, raising the worry of transplant rejection.

I want to be honest that this is a theoretical concern based on how these things behave, not proven in transplant patients. But on top of that, greater celandine has been tied to serious liver injury, which is reason enough to avoid it here. Please loop in your transplant team before taking any herbal product.

About Greater Celandine

What is Greater Celandine?

Greater Celandine
  • Digestive and gallbladder complaints
  • Stomach cramps and bloating
  • Topical use for warts and skin growths
  • Liver and gallbladder 'cleansing'
  • Mild pain relief

Greater celandine is a traditional herb most often promoted for digestive and gallbladder complaints, but solid human evidence for any use is lacking. More importantly, it has been linked to serious and sometimes severe liver injury, so most experts advise against taking it by mouth. If you are considering it, talk with your pharmacist or doctor first.
