Trichopus Zeylanicus and Natalizumab

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Natalizumab

Natalizumab falls under IMMUNOSUPPRESSANTS — the group Trichopus Zeylanicus interacts with.

Theoretically, Trichopus zeylanicus might reduce the effects of immunosuppressants. Animal research suggests that Trichopus zeylanicus might have 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 thinking on combining Trichopus zeylanicus with Tysabri (natalizumab). Natalizumab works by calming down part of your immune system, which is how it controls MS flare-ups. This herb has been suggested in animal and lab studies to do the opposite, gently stimulating the immune system. So in theory, taking them together could push against each other and make your natalizumab a little less effective at keeping symptoms in check.

I want to be honest with you: this concern is based on very weak, early evidence, not on real human cases, so the actual risk is uncertain. Still, since MS treatment matters a lot, I'd loop in your neurologist or pharmacist before adding this supplement rather than starting it on your own.

From our pharmacist’s overview on the Natalizumab page

“Natalizumab (Tysabri) works by quieting an overactive immune system in multiple sclerosis and Crohn's disease, and that is exactly why this list of 70 supplements deserves real care rather than a shrug. Fifty-three of them, ashwagandha among the familiar names, are believed to stimulate immune function, which could work directly agains…”
