HEPATOTOXIC DRUGS

Why this applies to Ozanimod Hydrochloride

Ozanimod Hydrochloride falls under HEPATOTOXIC DRUGS — the group Kudzu interacts with.

Theoretically, concomitant use might have additive hepatotoxic effects.
There is some concern that kudzu can adversely affect the liver.
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 kudzu and Zeposia (ozanimod). Ozanimod can sometimes raise your liver enzymes, which is why your doctor checks bloodwork before you start it and watches for things like belly pain, nausea, dark urine, or yellowing of the skin or eyes. Kudzu has its own reputation for occasionally stressing the liver. Put them together and the worry is that those effects could stack up.

I'll be honest with you though: this is a theoretical caution based on how each one behaves, not proof that they cause harm together. It isn't about kudzu changing your ozanimod levels. Still, since your liver is already being monitored on this medication, it's worth a quick chat with your pharmacist or doctor before adding kudzu.
