Fulvic Acid and Tildrakizumab-Asmn

Moderate

IMMUNOSUPPRESSANTS

Theoretically, taking fulvic acid might decrease the effects of immunosuppressive therapy.

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 fulvic acid with Ilumya (tildrakizumab). Ilumya is an injectable antibody that calms down an overactive part of your immune system to clear up those thick, scaly psoriasis plaques. The concern is that fulvic acid may do the opposite, in animal studies it seemed to rev up immune activity. If that happened in people, it could theoretically work against your medication and let your psoriasis flare back up.

I want to be honest though, this is purely theoretical and based on animal and lab data, not real human cases. There's no proof it actually weakens Ilumya in people. Still, since you're paying good money for a treatment that's helping, it's worth a quick chat with your dermatologist or pharmacist before adding fulvic acid. Don't stop anything on your own.

Fulvic acid is a natural compound formed when plants and microbes break down in soil, and it is sold as a supplement for energy, gut, and overall wellness.
