The bottom line No known interaction

We found no known interaction between Aletris and Diroximel Fumarate 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 Diroximel Fumarate states a food rule worth keeping to.

Aletris and Diroximel Fumarate

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 Diroximel Fumarate and Aletris 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 Diroximel Fumarate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diroximel Fumarate is filed under 3 classifications — immunosuppressants, hepatotoxic drugs, oral drugs. Aletris has documented interactions with 4 drug classes — the most serious being estrogens (moderate), antacids (minor) and h2-blockers (minor) — and none of Diroximel Fumarate’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 Aletris Itself Has Been Linked To

This is not an interaction — nothing below involves Diroximel Fumarate. It is the side-effect record for Aletris on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Aletris, this list is the first place to look.

  • Dizziness Additional detail

    “There is currently a limited amount of information available about the adverse effects of aletris. Orally, aletris has been reported to cause colic, stupefaction, and vertigo (6).”

Everything above comes from the Natural Medicines adverse-effect record for Aletris — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Diroximel Fumarate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Diroximel Fumarate column appears here.

How to take them

Some Diroximel Fumarate Products Have a Food Rule — Aletris Should Not Break It

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

If taken with food, avoid a high-fat, high-calorie meal/snack; the meal/snack should contain no more than 700 calories and no more than 30 g fat [see Warnings and Precautions ( 5.6 ) and Clinical Pharmacology ( 12.3 )] .

From the Dosage and Administration section of the FDA label we read for Diroximel Fumarate — where that label names a specific product, the instruction is that product's. See the Diroximel Fumarate 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.

From our pharmacist’s overview on the Diroximel Fumarate page

“Diroximel fumarate (Vumerity) treats relapsing multiple sclerosis by quieting an overactive immune system, and I read its interaction list with real seriousness. Four of the 106 entries rate major, and none are exotic.”

About Aletris

What is Aletris?

Aletris
  • Menstrual complaints
  • Digestive upset and colic
  • Loss of appetite
  • Female reproductive tonic
  • Rheumatic discomfort

Aletris (true unicorn root or colic root) is a North American herb traditionally used for menstrual problems and digestive complaints, but there is little to no modern human research to show it works. Because safety is poorly studied, it should be avoided during pregnancy and breastfeeding, and anyone considering it should first talk with a pharmacist or doctor.

Aletris farinosa · Nartheciaceae · Root and rhizome · Dried root, tincture, liquid extract, capsules, tea

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

Aletris: dosing

There is no established, scientifically supported dose for Aletris. Traditional dosing has varied widely depending on the form (dried root, tea, or tincture) and is not based on modern research.If you choose to use a product, follow the directions on the label and do not exceed them.

Taking Aletris and Diroximel Fumarate Together: Common Questions

Is it safe to take Aletris with Diroximel Fumarate?
We do not list a known interaction between Aletris and Diroximel Fumarate. 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 Aletris and Diroximel Fumarate at the same time of day?
At least one FDA label for a product containing Diroximel Fumarate says to take it with food. If you take Aletris on an empty stomach out of habit, keep them separate and take Diroximel Fumarate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Diroximel Fumarate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Aletris and Diroximel Fumarate combination checked?
Interactions in our licensed database are recorded against drug classes. Diroximel Fumarate is filed under 3 classifications, and Aletris has documented interactions with 4 drug classes — none of Diroximel Fumarate'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 Aletris interact with any other medications?
Yes. Aletris has 77 documented drug interactions in our database — Diroximel Fumarate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Yes. Diroximel Fumarate has documented interactions with 106 supplements in our database — Aletris is not one of them. The Diroximel Fumarate interaction page linked on this page lists every one, ranked by severity.
