Monobenzone vs Benoquin: Are They the Same Thing?
Table of Contents
The Short Answer
Monobenzone and Benoquin are the same active pharmaceutical ingredient. Benoquin was simply the brand name under which monobenzone 20% cream was marketed by Valeant/ICN Pharmaceuticals before the brand was discontinued. There is no chemical or therapeutic difference between "monobenzone" and "Benoquin" — one is the generic/chemical name, the other was a commercial brand name for the identical compound. The distinction matters because these agents are not interchangeable: monobenzone's permanent, irreversible effect makes it appropriate only for extensive vitiligo (50%+ body surface area) where a uniform depigmented result is the goal, while reversible options like hydroquinone or phototherapy remain first-line for limited vitiligo or non-vitiligo hyperpigmentation. A dermatologist can help determine which category fits a specific case before treatment begins.

Why Was Benoquin Discontinued?
Benoquin was discontinued for commercial reasons — not due to safety concerns or regulatory withdrawal. The active ingredient monobenzone remains FDA-recognised for its approved indication (permanent depigmentation in extensive vitiligo). When a branded pharmaceutical is discontinued, other manufacturers can continue producing the same active ingredient under different brand names, provided they meet applicable pharmaceutical manufacturing standards.
This is exactly what happened with monobenzone: Behvazan Pharmaceutical Co. in Rasht, Iran continued manufacturing monobenzone 20% cream under the brand name Monozan®, using the same active ingredient at the same concentration.
Is Monozan a Legitimate Benoquin Replacement?
Yes. Monozan contains monobenzone at 20% concentration — chemically and pharmacologically identical to the monobenzone in the original Benoquin formulation. The therapeutic mechanism, expected timeline, and side effect profile are the same, because the active ingredient driving all of these is unchanged.
What About Compounded "Benoquin"?
Some US compounding pharmacies still prepare monobenzone 20% cream and may informally refer to it as "Benoquin" even though the branded product itself is discontinued. This compounded product is also monobenzone — just prepared by a different route (compounding vs. commercial manufacturing) and typically at a significantly higher price ($150-300+ per tube) than internationally sourced Monozan.
Where to Buy Monobenzone Today
Since "Benoquin" is no longer commercially available under that name, patients seeking monobenzone cream today have two realistic options:
- US compounding pharmacies: Require a prescription, typically $150-300+ per tube, limited to 20% concentration
- International pharmaceutical suppliers (e.g., GulfDermaCare): Monozan 20%, 40%, and 60% concentrations, from $12, shipped worldwide with full documentation
