Medically reviewed by · Updated June 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Kale and Nifurtimox 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 Nifurtimox states a food rule worth keeping to.

Kale and Nifurtimox

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 Nifurtimox and Kale 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 Kale at all — not against Nifurtimox, 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 Nifurtimox’s Own FDA Label Lists

This is not an interaction — none of it involves Kale. These are the most notable effects listed in the ADVERSE REACTIONS section of Nifurtimox’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. 2 of them are worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Weight loss
  • Reduced appetite
  • Fever
  • Stomach pain
  • A skin rash
  • Vomiting
  • Headache
  • Nausea

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

How to take them

Some Nifurtimox Products Have a Food Rule — Kale Should Not Break It

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

LAMPIT tablets must be taken with food ( 2.1 ) Dosage of LAMPIT in Pediatric Patients (birth a to less than 18 years of age) (2.2) Body Weight Group Total Daily Dose of nifurtimox (mg/kg) 41 kg or greater 8 to 10 Less than 41 kg 10 to 20 a Term newborn with body weight greater than or equal to 2.5 kg • Administer LAMPIT tablets orally, three times daily with food for

From the Dosage and Administration section of the FDA label we read for Nifurtimox — 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.

From our pharmacist’s overview on the Nifurtimox page

“Nifurtimox (Lampit) treats Chagas disease over a course lasting weeks, and it only works if enough of each dose is absorbed, which is why the 17 supplements flagged here call for real vigilance. Every single one can change how oral medications are taken up from the gut.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Kale is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Kale reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Kale and Nifurtimox records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Kale

What is Kale?

  • General nutrition and antioxidants
  • Heart health support
  • Eye health
  • Bone health
  • Digestive health and fiber

Kale is a nutrient-dense leafy green vegetable that is rich in vitamins, minerals, fiber, and antioxidants. Eaten as a normal food it is very healthy for most people, but it is a whole food rather than a proven treatment for any specific disease. People taking blood thinners or with thyroid concerns may need to be mindful of how much they eat.

Brassica oleracea var. acephala · Brassicaceae · Leaves · Fresh or cooked leaves, juice, powder, capsules, smoothies

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

Kale: dosing

There is no established 'dose' of kale because it is a food, not a standardized medicine. As a vegetable, it can be included as part of a balanced diet the way you would eat any leafy green.For kale powders, capsules, or juices, no proven therapeutic dose exists.
