Umckaloabo 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 Umckaloabo interacts with.

Theoretically, Pelargonium sidoides might decrease the effectiveness of immunosuppressant therapy.
In vitro research suggests that Pelargonium sidoides 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 concern with pairing Umckaloabo (Pelargonium sidoides) and basiliximab. Basiliximab is given around the time of a kidney transplant to quiet down your immune system so your body doesn't reject the new organ. Umckaloabo works in the opposite direction. Lab studies suggest it can stimulate the immune system, which is great for fighting off a chest infection but not what you want when a medication is purposely trying to hold your immune system back.

In theory, that push-and-pull could make basiliximab less effective and slightly raise the worry of rejection. I want to be honest, though: this is based on test-tube research, not real patient cases, so it's more of a caution than a proven problem. Since basiliximab protects a transplanted organ, don't take any chances. Please check with your transplant team or pharmacist before using it.

About Umckaloabo

What is Umckaloabo?

Umckaloabo
  • Acute bronchitis
  • Common cold
  • Sinusitis
  • Sore throat
  • Upper respiratory infections

Umckaloabo is a root extract from a South African geranium that is most studied for short-term relief of acute bronchitis and other respiratory infections. Some clinical research suggests it may help symptoms resolve a bit faster, but the quality of evidence is mixed and it is not a cure. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a chronic illness.
