Thunder God Vine and Teclistamab-cqyv

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Teclistamab-cqyv

Teclistamab-cqyv falls under IMMUNOSUPPRESSANTS — the group Thunder God Vine interacts with.

Theoretically, thunder god vine might enhance the effects of immunosuppressant drugs.
Large doses of thunder god vine may suppress immune function.
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 thing about Tecvayli (teclistamab): it's a powerful bispecific antibody used for multiple myeloma, and it already works by pushing your immune system to attack cancer cells. A known trade-off is that it can leave you more open to infections and can lower your blood counts. Thunder God Vine, on the other hand, is thought to calm and dampen the immune system, especially at larger or concentrated doses.

Stacking a herb that quiets immune function on top of a drug that's already affecting your immune defenses could, in theory, leave you more vulnerable to infections. I'll be honest, this is a theoretical concern based on how each one works, not from studies pairing them. Still, with a serious drug like this, please loop in your oncology team before adding Thunder God Vine.
