Drug & supplement interaction

American Pawpaw + Edaravone

Edaravone brand names: Radicava, Radicava ORS.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between American Pawpaw and Edaravone 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 Edaravone states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

American Pawpaw and Edaravone

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 Edaravone and American Pawpaw 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.

American Pawpaw safety at a glance

American Pawpaw overall Use caution The ripe fruit is generally eaten as food, but concentrated leaf, twig, and seed extracts may be toxic and lack good safety data.
Pregnancy Avoid There is not enough safety information, and concentrated extracts may be harmful, so avoid during pregnancy.
Breastfeeding Avoid Safety has not been studied, so avoid concentrated pawpaw 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 Edaravone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Edaravone is filed under a single classification — oral drugs. American Pawpaw has documented interactions with 1 drug class — the most serious being antineoplastics (minor) — and none of Edaravone’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

No Interaction Found — But Data Suggests American Pawpaw and Edaravone May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • A skin rash Additional detail

    Listed in the ADVERSE REACTIONS section of the FDA label for Edaravone. Read the label on DailyMed ›

Reported for American Pawpaw but not commonly for Edaravone: hives, vomiting and nausea.

Effects for Edaravone come from the ADVERSE REACTIONS section of its FDA label; effects for American Pawpaw come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,540 voluntary FDA FAERS reports for Edaravone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Edaravone Products Have a Food Rule — American Pawpaw Should Not Break It

At least one FDA label for a product containing Edaravone says to take it on an empty stomach. Most supplements — American Pawpaw included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Edaravone on its own and move American Pawpaw to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Edaravone 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.

RADICAVA ORS should be taken in the morning on an empty stomach after overnight fasting.

From the Dosage and Administration section of the FDA label we read for Edaravone — 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 American Pawpaw

What is American Pawpaw?

American Pawpaw
  • Anticancer interest
  • Lice and head lice treatment (topical)
  • Traditional digestive remedy
  • General wellness/antioxidant
  • Insecticide (historical seed use)

American pawpaw is a North American fruit tree whose leaves, twigs, and seeds contain compounds called acetogenins that have shown cancer-cell-killing activity in laboratory studies. However, strong human evidence for any health benefit is lacking, and the seeds, bark, and unripe parts can be toxic, so supplements should be used cautiously and only under professional guidance.

Asimina triloba · Annonaceae · Fruit, seeds, bark, leaves, and twigs · Fresh fruit, capsules, extracts, and standardized acetogenin products

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

American Pawpaw: dosing

There is no established standardized dose for American pawpaw supplements. Products vary widely in strength and which part of the plant they use, which makes safe dosing hard to determine.If you choose to use a pawpaw product, follow the directions on the label and do not exceed them.

Taking American Pawpaw and Edaravone Together: Common Questions

Is it safe to take American Pawpaw with Edaravone?
We do not list a known interaction between American Pawpaw and Edaravone. 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.
Do American Pawpaw and Edaravone have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take American Pawpaw and Edaravone at the same time of day?
At least one FDA label for a product containing Edaravone says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Edaravone on its own and move American Pawpaw to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the American Pawpaw and Edaravone combination checked?
Interactions in our licensed database are recorded against drug classes. Edaravone is filed under 1 classification, and American Pawpaw has documented interactions with 1 drug class — none of Edaravone'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 American Pawpaw interact with any other medications?
Yes. American Pawpaw has 25 documented drug interactions in our database — Edaravone 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 Edaravone interact with any supplements?
Yes. Edaravone has documented interactions with 17 supplements in our database — American Pawpaw is not one of them. The Edaravone interaction page linked on this page lists every one, ranked by severity.
