Coriander and Thiothixene

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Thiothixene

Thiothixene falls under PHOTOSENSITIZING DRUGS — the group Coriander interacts with.

Theoretically, coriander might increase the risk of photosensitivity when taken with photosensitizing drugs.
Evidence from in vitro research suggests that coriandrin, a constituent of coriander, has photosensitizing 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 gist: thiothixene (Navane) can already make your skin more sensitive to sunlight, meaning you may sunburn faster than you'd expect. Coriander contains a compound called coriandrin that, at least in lab studies, seems to do something similar. So the theory is that pairing the two could add up and leave your skin a bit more sun-sensitive than usual.

I want to be honest about the evidence here: this is mostly theoretical and based on test-tube data, not real patient reports. The amount of cilantro you'd sprinkle on your tacos almost certainly won't matter. Concentrated coriander extracts or essential oils are a different story. Either way, just play it safe in the sun, use sunscreen, and check with your pharmacist or doctor if you have questions.

This page covers Coriander only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Thiothixene page lists 51 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Indian Snakeroot (major), Rauvolfia Vomitoria (major), Alfalfa (moderate) and Angelica Archangelica (moderate).

By severity: 3 major · 37 moderate · 11 minor.

From our pharmacist’s overview on the Thiothixene page

“Activated charcoal is the entry to know first with thiothixene (Navane). It can bind the drug in the gut and carry it out of the body, and for an antipsychotic controlling psychotic symptoms, a dose that quietly disappears risks relapse.”
