Additionally, although there is no interaction, the label for Clofazimine states a food rule worth keeping to.

Chinese Prickly Ash 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 Chinese Prickly Ash 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.

Chinese Prickly As... overall Use caution Generally safe as a food spice, but medicinal-strength extracts are not well studied in people.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Chinese Prickly Ash has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (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 Clofazimine’s Own FDA Label Lists

This is not an interaction — none of it involves Chinese Prickly Ash. These are the most notable effects listed in the ADVERSE REACTIONS section of Clofazimine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 9 of them are worth acting on rather than waiting out — marked below.

  • An irregular heartbeat Worth acting on mentioned in 12.0% of FDA reports for Clofazimine
  • A bowel blockage Worth acting on
  • Bleeding in the gut Worth acting on
  • Low potassium Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Anemia Worth acting on mentioned in 7.5% of FDA reports for Clofazimine
  • Low mood Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A change in taste

Showing the 10 most notable of 24 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Clofazimine. Read the label on DailyMed › 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. Chinese Prickly Ash’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Chinese Prickly Ash side to compare — that is a limit of the record, not a statement that Chinese Prickly Ash has no side effects.

How to take them

Some Clofazimine Products Have a Food Rule — Chinese Prickly Ash Should Not Break It

At least one FDA label for a product containing Clofazimine says to take it with food. If you take Chinese Prickly Ash 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 Chinese Prickly Ash 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 Chinese Prickly Ash

What is Chinese Prickly Ash?

  • Digestive upset and stomach pain
  • Toothache and oral numbing
  • Antimicrobial and antiparasitic use
  • Cooking spice (Sichuan pepper)
  • Mild pain relief

Chinese Prickly Ash is the fruit husk of Zanthoxylum bungeanum, best known as the Sichuan pepper that creates a tingling, numbing sensation on the tongue. It is widely used in cooking and traditional Chinese medicine for digestive complaints and pain, but strong human evidence for medicinal benefits is limited. Use culinary amounts safely, but talk to a pharmacist or doctor before using concentrated extracts.

Zanthoxylum bungeanum · Rutaceae · Dried fruit husks (pericarp), and sometimes the seeds and essential oil · Dried whole spice (Sichuan pepper), ground powder, essential oil, decoctions, and capsules

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

Chinese Prickly Ash: dosing

There is no established standardized medicinal dose for Chinese Prickly Ash. As a cooking spice, people use small culinary amounts to taste.If you choose a supplement, extract, or essential oil product, follow the directions on the product label and do not exceed them.

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.

Electrocardiogram qt prolonged 762 reports
Nausea 563 reports
Vomiting 503 reports
Anemia 474 reports
Dyspnea 403 reports

Taking Chinese Prickly Ash and Clofazimine Together: Common Questions

Is it safe to take Chinese Prickly Ash with Clofazimine?

If you take Chinese Prickly Ash on an empty stomach out of habit, keep them separate and take Clofazimine with a meal where the label says to.
