Edaravone brand names: Radicava, Radicava ORS.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Butylated Hydroxytoluene (bht) 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.

Butylated Hydroxytoluene (bht) 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 Butylated Hydroxytoluene (bht) 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 Butylated Hydroxytoluene (bht) at all — not against Edaravone, 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 Butylated Hydroxytoluene (bht) Itself Has Been Linked To

This is not an interaction — nothing below involves Edaravone. It is the side-effect record for Butylated Hydroxytoluene (bht) on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Butylated Hydroxytoluene (bht), this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Fainting / Confusion Worth acting on Additional detail

    “Orally, BHT can cause severe gastritis characterized by severe epigastric pain, nausea, and vomiting. Symptoms may progress to weakness, dizziness, confusion, slurred speech, unsteady gait, and loss of consciousness. BHT is highly lipid soluble. It may cross the blood brain barrier, causing psychotropic symptoms. BHT has been associated with development of cancer;”

How to take them

Some Edaravone Products Have a Food Rule — Butylated Hydroxytoluene (bht) Should Not Break It

At least one FDA label for a product containing Edaravone says to take it on an empty stomach. Most supplements — Butylated Hydroxytoluene (bht) 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 Butylated Hydroxytoluene (bht) 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. See the Edaravone drug page ›

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 Butylated Hydroxytoluene (bht)

What is Butylated Hydroxytoluene (bht)?

  • Antioxidant supplement
  • Antiviral (popular self-treatment for herpes-type viruses)
  • Food and supplement preservative
  • General 'anti-aging' use

Butylated hydroxytoluene (BHT) is a man-made antioxidant used mainly as a preservative in foods, cosmetics, and supplements. Some people take it as a supplement hoping for antiviral or anti-aging effects, but human evidence for these uses is very weak, and taking concentrated BHT carries real safety concerns. Talk with a pharmacist or doctor before using it as a supplement.

Synthetic compound (not from a plant) · Capsules, tablets, liquid drops, powder

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

Butylated Hydroxytoluene (bht): dosing

There is no established or proven safe supplement dose of BHT. It is not a standardized medical treatment, and doses found in supplements vary widely.If you choose to use a BHT product, follow the directions on the label and do not exceed them.
