Chlorophyll 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 Chlorophyll interacts with.

Theoretically, concomitant use of chlorophyll with photosensitizing drugs may have additive effects.
Chlorophyll has been reported to cause photosensitization. In two case reports, pseudoporphyria developed after oral intake of chlorophyll. Theoretically, concomitant use with other photosensitizing drugs may exacerbate this effect.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: thiothixene (Navane) can make your skin more sensitive to sunlight, meaning you may sunburn faster or break out in a rash with sun exposure. Chlorophyll supplements have also been linked, in a couple of case reports, to a sun-triggered skin reaction. So the worry here is that the two together could add up and make your skin even touchier in the sun.

This isn't about chlorophyll changing how your body processes thiothixene. It's a skin-and-sunlight overlap, and honestly the evidence for chlorophyll's part is pretty thin (just a few reports). It's reasonable to be a little extra careful with sunscreen and covering up. If you want to use chlorophyll, run it by your pharmacist or doctor first.

See Every Supplement That Interacts With Thiothixene

This page covers Chlorophyll 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.”

About Chlorophyll

What is Chlorophyll?

Chlorophyll
  • Body and breath odor reduction
  • Wound healing (topical)
  • Detoxification
  • Antioxidant support
  • Skin health

Chlorophyll is the green pigment found in plants and algae, and supplements often use a stable form called chlorophyllin. It is most studied for reducing body and fecal odor and as a topical wound aid, but evidence for popular claims like detox and weight loss is weak. It is generally well tolerated for most adults, but talk with your pharmacist or doctor before starting, especially if you are pregnant or breastfeeding.
