Drug & supplement interaction

Cesium + Buproprion, Dextromethorphan

Buproprion, Dextromethorphan brand name: Auvelity.

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 Cesium and Buproprion, Dextromethorphan 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

Cesium and Buproprion, Dextromethorphan

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 Buproprion, Dextromethorphan and Cesium 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 Buproprion, Dextromethorphan

Interactions in our licensed database are recorded against drug classes, not just single drug names. Buproprion, Dextromethorphan is filed under 11 classifications — including antidepressant drugs, cytochrome p450 2b6 (cyp2b6) substrates, cytochrome p450 2d6 (cyp2d6) inhibitors. Cesium has documented interactions with 3 drug classes — the most serious being qt interval-prolonging drugs (major), corticosteroids (moderate) and diuretic drugs (moderate) — and none of Buproprion, Dextromethorphan’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 Cesium and Buproprion, Dextromethorphan 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.

Overlapping uses

What Buproprion, Dextromethorphan Is Prescribed For, and What Cesium Has Been Studied For

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

Buproprion, Dextromethorphan is prescribed for: Auvelity (dextromethorphan/bupropion) is approved to treat major depressive disorder (MDD) in adults. It is also approved to treat agitation associated with dementia due to Alzheimer's disease in adults. Auvelity is not intended as an as-needed treatment for Alzheimer's-related agitation — it is a scheduled, ongoing medication. It is not approved for use in children or adolescents.

Cesium has been studied for:

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

    Cesium for depression

    Although there has been interest in using oral cesium for depression, there is insufficient reliable information about the clinical effects of cesium for this purpose.

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 Buproprion, Dextromethorphan on your own; if you are taking Cesium for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Cesium

What is Cesium?

  • Marketed as an alternative cancer treatment ('high pH therapy')
  • Claimed to alter tumor pH
  • General 'alkaline' health claims

Cesium chloride is a mineral salt sold as an alternative cancer therapy ('high pH therapy'), but there is no reliable scientific evidence that it treats cancer or any other disease. It can cause dangerous heart rhythm problems and even death, so it should not be used. Talk to your doctor or pharmacist before taking any supplement, and never use cesium in place of proven medical care.

Mineral element (cesium chloride salt) · Capsules, powders, liquid solutions (often as cesium chloride)

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

Cesium: dosing

There is no safe or established dose for cesium chloride, and it is not approved as a medicine. Because it can cause life-threatening harm, no dosing recommendation can be given.We strongly advise against taking cesium chloride.

Taking Cesium and Buproprion, Dextromethorphan Together: Common Questions

Is it safe to take Cesium with Buproprion, Dextromethorphan?

Are Cesium and Buproprion, Dextromethorphan used for the same thing?
