Arrach and Ziprasidone

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Ziprasidone

Ziprasidone falls under PHOTOSENSITIZING DRUGS — the group Arrach interacts with.

Theoretically, concomitant use of arrach can increase risk of adverse effects, as unspecified Chenopodium species are associated with photosensitivity.
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 with Arrach and ziprasidone (Geodon): both can make your skin more sensitive to sunlight. Ziprasidone already carries a known risk of photosensitivity, meaning you may sunburn faster or break out in a rash with sun exposure. Some plants in the goosefoot family (which Arrach belongs to) have been linked to the same effect, so stacking the two could, in theory, add up.

I want to be honest, though: this is a theoretical concern based on how these substances behave, not on solid human studies. It isn't about Arrach changing how your body processes ziprasidone. Still, it's worth a quick chat with your pharmacist or doctor before combining them, and either way, using sunscreen and covering up outdoors is smart while on ziprasidone.

From our pharmacist’s overview on the Ziprasidone page

“Ziprasidone (Geodon) is an antipsychotic that already carries a warning about disturbing the heart's electrical rhythm, so a list with 11 major-rated interactions calls for real care before mixing in supplements. Most of the 188 ingredients on file touch the liver enzyme, CYP3A4, that clears ziprasidone from the body.”

About Arrach

What is Arrach?

Arrach
  • Painful menstruation
  • Nervous complaints
  • Digestive upset
  • Wound care
  • Insect repellent

Arrach (Chenopodium vulvaria) is a strong-smelling European herb that has been used in traditional folk medicine, mainly for menstrual and nervous complaints. There is very little modern scientific evidence to show that it works or is safe, so it is not recommended, especially during pregnancy or breastfeeding. Talk to your pharmacist or doctor before using any herbal product.

About Ziprasidone

What Is Ziprasidone Used For?

Brand name: Geodon
