Drug & supplement interaction

Rauwolscine + Clofazimine

Clofazimine brand name: Lamprene.

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 Rauwolscine and Clofazimine 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 Clofazimine states a food rule worth keeping to, and 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 Clofazimine

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 Clofazimine 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.

How we checked

Why No Interaction Is Listed for Clofazimine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Clofazimine is filed under 3 classifications — antibiotic drugs, photosensitizing drugs, oral 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 Clofazimine’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 Rauwolscine and Clofazimine 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.

  • Fever / Tiredness Additional detail

    Rauwolscine

    “Since rauwolscine is structurally related to yohimbine, rauwolscine might theoretically cause similar adverse effects. There is one report of a hypersensitivity reaction including fever, chills, malaise, itchy and scaly skin, progressive renal failure, and lupus-like syndrome associated with ingestion of a one-day dose of yohimbine.”

  • Headache Additional detail

    Rauwolscine

    Recorded for Rauwolscine in the same Natural Medicines adverse-effect record shown under Dizziness above.

    Clofazimine

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

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

Effects for Clofazimine 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 6,351 voluntary FDA FAERS reports for Clofazimine 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.

How to take them

Some Clofazimine Products Have a Food Rule — Rauwolscine Should Not Break It

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

2 DOSAGE AND ADMINISTRATION For dapsone-sensitive lepromatous leprosy, 100 mg (two 50 mg capsules) daily with meals as a part of a combination regimen for at least 2 years is recommended.

From the Dosage and Administration section of the FDA label we read for Clofazimine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

Everything else you take

See Every Supplement That Interacts With Clofazimine

This page covers Rauwolscine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Clofazimine page lists 64 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bacillus Coagulans (moderate).

By severity: 1 major · 52 moderate · 11 minor.

From our pharmacist’s overview on the Clofazimine page

“Clofazimine (Lamprene) treats leprosy for months or years, so anything that quietly drains its blood levels deserves genuine caution. Activated charcoal is the single major-rated interaction among the 64 on file, binding the drug and cutting how much reaches your body.”

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.

About Clofazimine

What Is Clofazimine Used For?

Brand name: Lamprene

Lamprene (clofazimine) is used to treat lepromatous leprosy — the most severe form of leprosy — including cases where the bacteria have become resistant to dapsone. It is also used when leprosy is complicated by erythema nodosum leprosum (ENL), a painful inflammatory reaction that can occur alongside the infection.

Lamprene is always used as part of a combination regimen with other anti-leprosy drugs. Using it alone for initial treatment raises the risk of drug resistance.

Most-Reported Side Effects for Clofazimine

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Rauwolscine and Clofazimine Together: Common Questions

Is it safe to take Rauwolscine with Clofazimine?
We do not list a known interaction between Rauwolscine and Clofazimine. 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 Clofazimine have any of the same side effects?
Yes — our sources link each of them separately to 7 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.
Should I take Rauwolscine and Clofazimine at the same time of day?
At least one FDA label for a product containing Clofazimine says to take it with food. If you take Rauwolscine on an empty stomach out of habit, keep them separate and take Clofazimine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Clofazimine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Rauwolscine and Clofazimine combination checked?
Interactions in our licensed database are recorded against drug classes. Clofazimine is filed under 3 classifications, and Rauwolscine has documented interactions with 6 drug classes — none of Clofazimine'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 — Clofazimine 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 Clofazimine interact with any supplements?
Yes. Clofazimine has documented interactions with 64 supplements in our database — Rauwolscine is not one of them. The Clofazimine interaction page linked on this page lists every one, ranked by severity.
