Drug & supplement interaction

Sulbutiamine + Epoetin Beta

Epoetin Beta brand names: Recormon, Mircera.

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

We found no known interaction between Sulbutiamine and Epoetin Beta 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 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.

Sulbutiamine and Epoetin Beta

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 Epoetin Beta and Sulbutiamine 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 Sulbutiamine at all — not against Epoetin Beta, 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.

No Interaction Found — But Data Suggests Sulbutiamine and Epoetin Beta May Share a Side Effect

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.

  • Headache Additional detail

    Sulbutiamine

    “Cases of headache, insomnia, tremor, and drowsiness were each reported in one patient (0.06% of patients) using a combination of anti-infective medication and sulbutiamine.”

    Epoetin Beta

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

Reported for Sulbutiamine but not commonly for Epoetin Beta: drowsiness, trouble sleeping, nausea and tremor or shakiness.

Effects for Epoetin Beta come from the ADVERSE REACTIONS section of its FDA label; effects for Sulbutiamine come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Epoetin Beta Is Prescribed For, and What Sulbutiamine Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Epoetin Beta is a prescription medicine with approved uses on its FDA label. Sulbutiamine is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Epoetin Beta is prescribed for: Mircera is used to treat anemia associated with chronic kidney disease (CKD) in adult patients, whether or not they are on dialysis. It is also approved for pediatric patients aged 3 months to 17 years who are on dialysis or not on dialysis, but only when they are converting from another ESA after their hemoglobin level has already been stabilized. Mircera is not indicated for anemia caused by cancer chemotherapy, and it is not a substitute for red blood cell (RBC) transfusions when anemia needs to be corrected immediately. It has not been shown to improve symptoms, fatigue, or quality of life.

Sulbutiamine has been studied for:

  • Fatigue studied, not established Sulbutiamine has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Sulbutiamine for fatigue

    Observational research has found that taking sulbutiamine 400 mg daily in addition to antibiotic treatment for 15 days is associated with improved energy levels and reduced weakness in patients with infection-associated fatigue.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Epoetin Beta on your own; if you are taking Sulbutiamine for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Epoetin Beta page

“Epoetin Beta (Recormon, Mircera) prompts the body to make more red blood cells, usually for anemia from kidney disease or chemotherapy, and its 23 supplement interactions warrant genuine care, starting with the single major one. Activated charcoal can cut exposure to many drugs regardless of how they are given, which could undercut a t…”

About Sulbutiamine

What is Sulbutiamine?

  • Fatigue and low energy
  • Memory and focus
  • Mental clarity
  • Mood support
  • Vitamin B1 deficiency support

Sulbutiamine is a man-made, fat-soluble form of vitamin B1 (thiamine) developed in Japan, often taken for fatigue and to support mental energy and focus. Human evidence is limited and mostly older or small, so its real benefits are uncertain. It is generally well tolerated short-term, but you should talk with a pharmacist or doctor before using it, especially if you have a health condition.

Synthetic compound (not from a plant) · Tablets, capsules

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

Sulbutiamine: dosing

There is no firmly established standard dose for sulbutiamine as a supplement. Amounts used in older studies and on product labels vary, and there is not enough strong evidence to recommend one clear dose.The safest approach is to follow the directions on the product label and not take more than suggested.

Taking Sulbutiamine and Epoetin Beta Together: Common Questions

Is it safe to take Sulbutiamine with Epoetin Beta?
We do not list a known interaction between Sulbutiamine and Epoetin Beta. 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 Sulbutiamine and Epoetin Beta have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Sulbutiamine and Epoetin Beta used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Sulbutiamine in each. That is a conversation for your prescriber, especially if Epoetin Beta is being adjusted to a target.
Does Epoetin Beta interact with any supplements?
Yes. Epoetin Beta has documented interactions with 23 supplements in our database — Sulbutiamine is not one of them. The Epoetin Beta interaction page linked on this page lists every one, ranked by severity.
