We found no known interaction between Tamarind and Thioridazine 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.

Tamarind 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 Tamarind 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. Tamarind has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), aspirin (moderate) and ibuprofen (advil, others) (moderate) — 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.

What Thioridazine’s Own FDA Label Lists

This is not an interaction — none of it involves Tamarind. These are the most notable effects listed in the ADVERSE REACTIONS section of Thioridazine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • 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
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on

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

What is Tamarind?

  • Constipation and digestive upset
  • Culinary flavoring
  • Fever and sore throat
  • Antioxidant support
  • Traditional wound or skin care

Tamarind is a tangy tropical fruit widely used in cooking and traditional medicine, mainly for digestion and as a mild laxative. While it is a nutritious food, strong human evidence for most of its medicinal claims is limited, so use it mainly as a food and talk to your pharmacist before using concentrated supplements.

Tamarindus indica · Fabaceae · Fruit pulp, seeds, leaves, and bark · Fruit pulp, paste, juice, candy, capsules, powder, and extracts

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

Tamarind: dosing

There is no official, standardized medicinal dose for tamarind. As a food, people eat it in the amounts found in recipes, drinks, or candies, which is generally fine.For supplements such as capsules, powders, or extracts, the best approach is to follow the directions on the product label.

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.
