The bottom line No known interaction

We found no known interaction between Tamarind and Ethambutol 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. Additionally, although there is no interaction, the label for Ethambutol states a food rule worth keeping to.

Tamarind and Ethambutol

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 Ethambutol 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 Ethambutol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ethambutol is filed under a single classification — oral drugs. 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 Ethambutol’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 Ethambutol’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 Ethambutol’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.

  • Loss of vision Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • A severe allergic reaction Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • An allergic reaction Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Ethambutol. 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.

How to take them

Some Ethambutol Products Have a Food Rule — Tamarind Should Not Break It

At least one FDA label for a product containing Ethambutol says to take it with food. If you take Tamarind on an empty stomach out of habit, keep them separate — and take Ethambutol with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ethambutol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Absorption is not significantly altered by administration with food.

From the Dosage and Administration section of the FDA label we read for Ethambutol — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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 Ethambutol

What Is Ethambutol Used For?

Brand names: Myambutol, Etibi

Ethambutol hydrochloride tablets are used to treat pulmonary tuberculosis — TB that affects the lungs. It must always be taken with at least one other anti-TB medication, never on its own.

For people being treated for TB for the first time, ethambutol is commonly paired with isoniazid, or with isoniazid and streptomycin. For people who have been treated for TB before, it is combined with other second-line anti-TB drugs chosen based on which medicines the bacteria are still sensitive to.

At least one FDA label for a product containing Ethambutol says to take it with food. If you take Tamarind on an empty stomach out of habit, keep them separate and take Ethambutol with a meal where the label says to.

Interactions in our licensed database are recorded against drug classes. Ethambutol is filed under 1 classification, and Tamarind has documented interactions with 3 drug classes — none of Ethambutol's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
