Bupropion brand names: Wellbutrin, Wellbutrin SR, Zyban, Wellbutrin XL, Aplenzin, and others.

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 Ergot and Bupropion 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.

Interaction report

Ergot and Bupropion

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 Bupropion and Ergot 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 Bupropion

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bupropion is filed under 6 classifications — including antidepressant drugs, cytochrome p450 2b6 (cyp2b6) substrates, cytochrome p450 2d6 (cyp2d6) inhibitors. Ergot has documented interactions with 4 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) inhibitors (moderate), ergot derivatives (moderate) and serotonergic drugs (moderate) — and none of Bupropion’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 Ergot and Bupropion 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. 2 of them are worth acting on rather than waiting out — marked below.

Effects for Bupropion come from the ADVERSE REACTIONS section of its FDA label; effects for Ergot come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 152,137 voluntary FDA FAERS reports for Bupropion 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.

Everything else you take

See Every Supplement That Interacts With Bupropion

This page covers Ergot only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bupropion page lists 46 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Artichoke (moderate) and Astaxanthin (moderate).

By severity: 1 major · 33 moderate · 12 minor.

From our pharmacist’s overview on the Bupropion page

“Bupropion (Wellbutrin, Zyban) deserves genuine care around supplements, and the entry to understand first is activated charcoal, the only major-rated interaction on this list. Charcoal and similar bulk products can soak up the drug in the gut and blunt its effect, so space them well apart from your dose.”

About Ergot

What is Ergot?

Ergot
  • Heavy menstrual or uterine bleeding
  • Bleeding after childbirth
  • Migraine headaches
  • Stimulating uterine contractions

Ergot is a toxic fungus that grows on rye and contains powerful chemicals (ergot alkaloids) that strongly narrow blood vessels and squeeze the uterus. Because raw ergot is poisonous and the dose is impossible to control safely, it should never be used as a home remedy or supplement. Some purified ergot chemicals are used as prescription drugs under strict medical supervision, but the crude herb is not safe to take.

Claviceps purpurea · Clavicipitaceae · The fungal mass (sclerotium) that grows on rye and other grasses · Historically used as crude dried fungus; purified ergot alkaloids are available only as prescription medicines (not as a dietary supplement)

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

Ergot: dosing

There is no safe established dose of crude ergot for self-care, and it should not be taken as a supplement. The amount of active chemical in the raw fungus varies and cannot be measured reliably at home, which makes poisoning very easy.The only safe way ergot chemicals are used is as purified, carefully measured prescription medicines given and monitored by a healthcare professional. Do not try to make or take any ergot preparation on your own.

About Bupropion

What Is Bupropion Used For?

Brand names: Wellbutrin, Wellbutrin SR, Zyban, Wellbutrin XL, Aplenzin, Forfivo XL

Bupropion is FDA-approved to treat major depressive disorder (MDD) — a form of clinical depression. Extended-release formulations (XL and hydrobromide versions, including Aplenzin) are also approved for the prevention of seasonal affective disorder (SAD), the pattern of depression that tends to arrive in autumn and winter.

Not all formulations share every indication. Aplenzin (bupropion hydrobromide extended-release) and bupropion hydrochloride extended-release tablets (XL) are indicated for both MDD and SAD. Bupropion hydrochloride extended-release tablets (SR) and bupropion hydrochloride immediate-release tablets are indicated for MDD only.

Taking Ergot and Bupropion Together: Common Questions

Is it safe to take Ergot with Bupropion?
We do not list a known interaction between Ergot and Bupropion. 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 Ergot and Bupropion have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
How was the Ergot and Bupropion combination checked?
Interactions in our licensed database are recorded against drug classes. Bupropion is filed under 6 classifications, and Ergot has documented interactions with 4 drug classes — none of Bupropion'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 Ergot interact with any other medications?
Yes. Ergot has 462 documented drug interactions in our database — Bupropion 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 Bupropion interact with any supplements?
Yes. Bupropion has documented interactions with 46 supplements in our database — Ergot is not one of them. The Bupropion interaction page linked on this page lists every one, ranked by severity.
