Collagen Type I (native) + Clofazimine
Clofazimine brand name: Lamprene.
We found no known interaction between Collagen Type I (native) 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.
Collagen Type I (native) 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 Collagen Type I (native) 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Collagen Type I (native) at all — not against Clofazimine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Clofazimine Products Have a Food Rule — Collagen Type I (native) Should Not Break It
At least one FDA label for a product containing Clofazimine says to take it with food. If you take Collagen Type I (native) 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. See the Clofazimine drug page ›
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.
See Every Supplement That Interacts With Clofazimine
This page covers Collagen Type I (native) 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 Collagen Type I (native)
What is Collagen Type I (native)?
- Skin health and wrinkles
- Joint comfort and arthritis
- Bone strength
- Hair and nail support
- Wound and tissue repair
Type I collagen is the most abundant protein in human skin, bones, and tendons, and it is sold as a supplement to support skin, joints, and bones. 'Native' (undenatured) Type I collagen keeps its natural triple-helix structure rather than being broken down into peptides. Early research is promising for skin and joints, but evidence is still limited, and most products are generally well tolerated.

An interaction check asks whether these two react with each other — it does not ask whether Collagen Type I (native) is a good idea for someone in your situation. Here is what our Collagen Type I (native) record says about it on its own.
Collagen Type I (native): dosing
There is no official standardized dose for native Type I collagen, and the right amount depends on the specific product. Doses used in studies vary widely depending on the form (powder versus tablet) and whether the collagen is native or hydrolyzed.The safest approach is to follow the directions on the product label and 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.
