The bottom line No known interaction

We found no known interaction between Ashitaba 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.

Interaction report

Ashitaba 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 Ashitaba 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.

Ashitaba safety at a glance

Ashitaba overall Use caution Likely safe as a food, but supplement safety has not been well studied.
Pregnancy Avoid Not enough safety data, so avoid concentrated supplements during pregnancy.
Breastfeeding Avoid Not enough safety data, so avoid concentrated supplements while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Nifurtimox

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nifurtimox is filed under a single classification — oral drugs. Ashitaba has documented interactions with 1 drug class — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Nifurtimox’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 to actually watch for

What Nifurtimox’s Own FDA Label Lists

This is not an interaction — none of it involves Ashitaba. 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 › Ashitaba’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Ashitaba side to compare — that is a limit of the record, not a statement that Ashitaba has no side effects.

How to take them

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

At least one FDA label for a product containing Nifurtimox says to take it with food. If you take Ashitaba 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.

Everything else you take

See Every Supplement That Interacts With Nifurtimox

This page covers Ashitaba only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nifurtimox page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

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.”

About Ashitaba

What is Ashitaba?

Ashitaba
  • General wellness and longevity
  • Antioxidant support
  • Heart and cholesterol health
  • Digestive and stomach support
  • Anti-inflammatory

Ashitaba is a leafy plant from Japan that is eaten as a vegetable and taken as a supplement for general health, antioxidant, and heart benefits. Most of the supporting research comes from laboratory and animal studies, so its real benefits in people are still uncertain. It appears generally well tolerated as a food, but talk to your pharmacist or doctor before using concentrated supplements.

Angelica keiskei · Apiaceae · Leaves, stems, and roots · Tea, capsules, powder, dried leaves, fresh vegetable, juice

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

Ashitaba: dosing

There is no well-established, standardized dose for Ashitaba supplements. Studies have used different forms and amounts, so a single "correct" dose has not been set.If you choose to use an Ashitaba product, follow the directions on the label and do not exceed the recommended amount.

Taking Ashitaba and Nifurtimox Together: Common Questions

Is it safe to take Ashitaba with Nifurtimox?
We do not list a known interaction between Ashitaba and Nifurtimox. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Ashitaba and Nifurtimox at the same time of day?
At least one FDA label for a product containing Nifurtimox says to take it with food. If you take Ashitaba on an empty stomach out of habit, keep them separate and take Nifurtimox with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Nifurtimox products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Ashitaba and Nifurtimox combination checked?
Interactions in our licensed database are recorded against drug classes. Nifurtimox is filed under 1 classification, and Ashitaba has documented interactions with 1 drug class — none of Nifurtimox'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.
Does Ashitaba interact with any other medications?
Yes. Ashitaba has 186 documented drug interactions in our database — Nifurtimox is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Nifurtimox interact with any supplements?
Yes. Nifurtimox has documented interactions with 17 supplements in our database — Ashitaba is not one of them. The Nifurtimox interaction page linked on this page lists every one, ranked by severity.
