Thunder God Vine and Fluvoxamine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Thunder God Vine interacts with whole categories of medication. Fluvoxamine falls into 2 of those categories, so it can interact with Thunder God Vine in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Fluvoxamine

Fluvoxamine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Thunder God Vine interacts with.

Theoretically, thunder god vine might increase the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that triptolide, a constituent of thunder god vine, inhibits CYP1A2 enzymes in human microsomes. This interaction has not been reported in humans.
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 idea behind this pairing. Your body uses a liver enzyme called CYP1A2 to help clear fluvoxamine (Luvox). Lab studies suggest a compound in Thunder God Vine called triptolide can slow that same enzyme down. If that holds true in people, fluvoxamine could clear more slowly and build up a bit, which might mean stronger SSRI side effects like nausea, drowsiness, headache, jitteriness, or trouble sleeping.

I want to be honest about the strength of this, though. So far it's only been seen in a test tube, not in actual patients, so it's theoretical. That said, Thunder God Vine itself can be toxic if dosed wrong and really should only be used under a doctor's care. Please loop in your pharmacist or prescriber before combining them, and don't change your fluvoxamine on your own.

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

2 of 2

Fluvoxamine also falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS.

Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of thunder god vine constituents.
Inhibitors of CYP3A4 can increase the concentration of triptolide, a thunder god vine constituent, and its derivative (5R)-5-hydroxytriptolide. In vitro research shows that triptolide and (5R)-5-hydroxytriptolide are about 94% and 64% metabolized by CYP3A4, respectively.
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 key thing with this pair: it's not your Fluvoxamine that builds up, it's the Thunder God Vine. Fluvoxamine is a strong blocker of a liver enzyme called CYP3A4, and that's the same enzyme your body uses to break down triptolide, one of the herb's main active compounds. With the enzyme slowed down, more of that compound can hang around and pile up.

Why that matters: Thunder God Vine can already be toxic if dosed wrong, so higher levels may mean a greater chance of side effects like stomach upset, diarrhea, or liver and blood problems. To be fair, this is a theoretical concern based on lab work, not real patient reports. Still, please loop in your doctor or pharmacist before combining these two.

From our pharmacist’s overview on the Fluvoxamine page

“Fluvoxamine (Luvox), an SSRI used for OCD and depression, carries an interaction list that deserves genuinely careful reading. Two entries matter most: lithium, which alongside a serotonin-raising drug like fluvoxamine can tip toward serotonin syndrome, a dangerous excess of serotonin, and activated charcoal, which can soak up the medi…”
