Drug & supplement interaction

Rauwolscine + Dapsone

Dapsone brand names: Dapsone, Avlosulfon, Aczone.

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 Rauwolscine and Dapsone 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.

Rauwolscine and Dapsone

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 Dapsone and Rauwolscine 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.

Rauwolscine safety at a glance

How we checked

Why No Interaction Is Listed for Dapsone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dapsone is filed under 7 classifications — including antibiotic drugs, topical drugs, photosensitizing drugs. Rauwolscine has documented interactions with 6 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), calcium channel blockers (moderate) and clonidine (catapres) (moderate) — and none of Dapsone’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.

No Interaction Found — But Data Suggests Rauwolscine and Dapsone 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.

    Dapsone

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

Reported for Rauwolscine but not commonly for Dapsone: stomach upset, fainting, an allergic reaction and kidney problems.

Effects for Dapsone come from the ADVERSE REACTIONS section of its FDA label; effects for Rauwolscine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 10,640 voluntary FDA FAERS reports for Dapsone 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.

See Every Supplement That Interacts With Dapsone

This page covers Rauwolscine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dapsone page lists 215 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Grapefruit (major), Para-aminobenzoic Acid (paba) (major) and Siberian Cocklebur (major).

By severity: 7 major · 167 moderate · 41 minor.

From our pharmacist’s overview on the Dapsone page

“Dapsone treats serious conditions, from dermatitis herpetiformis to leprosy, and its supplement list is one I'd want a patient to read closely rather than skim. Most entries touch how the body handles dapsone through the CYP3A4 enzyme, so grapefruit can raise its blood level while St.”

About Rauwolscine

What is Rauwolscine?

  • Fat loss and weight management
  • Bodybuilding and physique support
  • Energy and stimulant effects
  • Athletic performance
  • Libido support

Rauwolscine (alpha-yohimbine) is a stimulant alkaloid closely related to yohimbine that is marketed mainly in fat-burning and pre-workout supplements. Human evidence for its benefits is very limited, and it can raise heart rate and blood pressure and cause anxiety, so it should be used with caution and is not recommended for people with heart conditions, anxiety, or during pregnancy or breastfeeding.

Bark and roots (alkaloid extracted from plants such as Rauvolfia and Pausinystalia) · Capsules, tablets, powders (often in fat-burner and pre-workout blends)

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

Rauwolscine: dosing

There is no well-established or standardized dose for rauwolscine, and it has not been studied the way medicines are. Supplement products vary widely in how much they contain, and it is often combined with other stimulants.If you choose to use a product that contains it, follow the directions on the label, do not exceed the recommended amount, and consider starting with the lowest amount to see how you react.

Taking Rauwolscine and Dapsone Together: Common Questions

Is it safe to take Rauwolscine with Dapsone?
We do not list a known interaction between Rauwolscine and Dapsone. 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 Rauwolscine and Dapsone have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Rauwolscine and Dapsone combination checked?
Interactions in our licensed database are recorded against drug classes. Dapsone is filed under 7 classifications, and Rauwolscine has documented interactions with 6 drug classes — none of Dapsone'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 Rauwolscine interact with any other medications?
Yes. Rauwolscine has 677 documented drug interactions in our database — Dapsone 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 Dapsone interact with any supplements?
Yes. Dapsone has documented interactions with 215 supplements in our database — Rauwolscine is not one of them. The Dapsone interaction page linked on this page lists every one, ranked by severity.
