Hercules Club and Thioridazine

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 Thioridazine and Hercules Club 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.

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.

How we checked

Why No Interaction Is Listed for Thioridazine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Thioridazine is filed under 10 classifications — including phenothiazines, antipsychotic drugs, cytochrome p450 2c19 (cyp2c19) substrates. Hercules Club has documented interactions with 3 drug classes — the most serious being antacids (minor), h2-blockers (minor) and proton pump inhibitors (ppis) (minor) — and none of Thioridazine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

  • A bowel blockage Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Wheezing Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Low mood Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Thioridazine. Read the label on DailyMed › Hercules Club’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hercules Club side to compare — that is a limit of the record, not a statement that Hercules Club has no side effects.

From our pharmacist’s overview on the Thioridazine page

“Thioridazine (Mellaril) is an older antipsychotic already known for disturbing the heart's rhythm, and the supplements that worry me most here do the same thing, stretching the QT interval further. Grapefruit in large amounts sits in that group, alongside ephedra and several other major-rated entries.”

About Hercules Club

What is Hercules Club?

Hercules Club
  • Toothache and mouth pain
  • Indigestion and sluggish digestion
  • Rheumatism and joint pain
  • Circulation (as a stimulant or tonic)
  • Sore throat

Hercules Club (southern prickly ash) is a traditional folk remedy used mainly for toothache, digestion, and joint pain, often by chewing the bark, which causes a tingling, numbing feeling in the mouth. Modern scientific evidence supporting these uses is very limited, and safety has not been well studied, so it is best to talk with a pharmacist or doctor before using it.

Zanthoxylum clava-herculis · Rutaceae · Bark, roots, and berries · Dried bark, tinctures, teas, and topical preparations

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

Hercules Club: dosing

There is no established standardized dose for Hercules Club. Traditional use varied widely, and product strengths differ from one brand to another.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Thioridazine

What Is Thioridazine Used For?

Brand name: Mellaril

Thioridazine Hydrochloride tablets are used for the management of schizophrenia — but only in patients who have already tried at least two other antipsychotic medications without adequate results, either because those drugs didn't work well enough or caused intolerable side effects.

Because thioridazine carries serious heart-rhythm risks, it is considered a last-resort option for schizophrenia, not a first-line treatment. It is not approved for dementia-related psychosis or any other psychiatric condition.
