The bottom line No known interaction

We found no known interaction between Wormseed and Clozapine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Wormseed and Clozapine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Clozapine and Wormseed in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Wormseed at all — not against Clozapine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Wormseed Itself Has Been Linked To

This is not an interaction — nothing below involves Clozapine. It is the side-effect record for Wormseed on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Wormseed, this list is the first place to look.

  • Muscle pain Additional detail

    “Orally, wormseed is unsafe.

    Serious Adverse Effects (Rare):

    Symptoms of poisoning are possible in the amounts traditionally used as medicine. Symptoms of toxicity include epileptiform spasms, gastroenteritis, kidney irritation, muscle twitching, stupor, visual disorders, and even death.”

    Wormseed · Natural Medicines adverse-effect record, reported in poisoning.

Everything above comes from the Natural Medicines adverse-effect record for Wormseed — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Clozapine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Clozapine column appears here.

Everything else you take

See Every Supplement That Interacts With Clozapine

This page covers Wormseed only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Clozapine page lists 212 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Henbane (major), Indian Snakeroot (major), Lithium (major) and Rauvolfia Vomitoria (major).

By severity: 6 major · 164 moderate · 42 minor.

From our pharmacist’s overview on the Clozapine page

“Clozapine (Clozaril, Versacloz) is usually the last-resort antipsychotic for schizophrenia, prescribed under close monitoring because small shifts in its blood level matter, so the 212 supplement interactions on file here deserve genuine care rather than a quick skim. Six are rated major.”

About Wormseed

What is Wormseed?

  • Intestinal worms and parasites
  • Digestive upset and gas
  • Cooking herb (culinary use as epazote)
  • Menstrual complaints
  • Respiratory symptoms

Wormseed (also called epazote) is a strong-smelling herb traditionally used to expel intestinal worms and to flavor food. Its essential oil is potentially toxic and has caused serious poisoning, so it should never be used in medicinal amounts without professional guidance. Modern deworming medicines are far safer and more reliable.

Dysphania ambrosioides · Amaranthaceae · Leaves, seeds, flowering tops, and essential oil (oil of chenopodium) · Tea, dried herb, tincture, and essential oil

An interaction check asks whether these two react with each other — it does not ask whether Wormseed is a good idea for someone in your situation. Here is what our Wormseed record says about it on its own.

Wormseed: dosing

There is no well-established or standardized medicinal dose for wormseed, and the essential oil has a narrow margin between a useful amount and a toxic one. As a food seasoning (epazote), the small amounts used in cooking are considered safe for most people.

About Clozapine

What Is Clozapine Used For?

Brand names: Clozaril, Versacloz

Clozapine is used for two specific situations. First, it is prescribed for people with severe schizophrenia who have already tried other antipsychotic medications and have not gotten adequate relief. It is reserved for this group because of its serious risks.

Second, clozapine is used to lower the chances of repeated suicidal behavior in people with schizophrenia or schizoaffective disorder who are considered to be at ongoing, chronic risk. It is not a first-choice medication — it is used when the need is serious and other options have fallen short.

Most-Reported Side Effects for Clozapine

From FAERS, the FDA’s public side-effect reporting system (124,830 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Neutropenia 18,897 reports
Hospitalisation 12,426 reports
Schizophrenia 4,692 reports
White blood cell count increased 4,508 reports
White blood cell count decreased 4,481 reports
