How to Pronounce Xeomin, and Every Other Neurotoxin Name

Part of Botox vs Other Brands
Xeomin is generally said ZEE-oh-min. Three syllables, hard Z at the front, stress on the first.
That is the answer most people came for. The rest of this page covers the other five, and the naming system underneath them, which turns out to be the part worth knowing because it tells you something real about the products.
1. The six brand names
| Brand | Generally said |
|---|---|
| Botox | BOH-tox |
| Dysport | DIS-port |
| Xeomin | ZEE-oh-min |
| Jeuveau | JOO-voh |
| Daxxify | DAX-ih-fy |
| Letybo | LET-ee-boh |
Xeomin is the one people ask about, and the reason is the X. In English an initial X is almost always said as Z, as in xylophone and Xerox, and Xeomin follows that. Nobody will misunderstand you if you say it with a hard X, and you will hear both in clinics.
Jeuveau is the second most misread. It is French in shape and the ending is not sounded as "voh-ay" or "voo". Two syllables.
2. The generic names, which look worse than they are
Every one of these products has an established name that looks unpronounceable and is not, because they are all the same word with a different two-syllable prefix bolted on.
| Brand | Established name | Prefix |
|---|---|---|
| Botox | onabotulinumtoxinA | ona |
| Dysport | abobotulinumtoxinA | abo |
| Xeomin | incobotulinumtoxinA | inco |
| Jeuveau | prabotulinumtoxinA-xvfs | pra |
| Daxxify | daxibotulinumtoxinA-lanm | daxi |
| Letybo | letibotulinumtoxinA-wlbg | leti |
The shared part, botulinumtoxinA, is said BOT-yoo-LIE-num TOX-in AY. Attach the prefix and you have all six. Xeomin's is IN-koh-BOT-yoo-LIE-num-TOX-in-AY.
The capital A on the end is not a typo and is not silent. It is the toxin serotype, type A, and every product approved for cosmetic use in the United States is a type A toxin.
3. The naming system, and why it exists
The prefixes are not branding. They were assigned deliberately, and the reason is a safety problem.
These products were once all called botulinum toxin type A, which made them sound like versions of one drug. They are not. Every label in the class states that its potency units are specific to that product's own assay and cannot be compared to or converted into the units of any other botulinum toxin. Sharing one name while having non-interchangeable doses is a recipe for exactly the error you would expect.
Distinct established names make that impossible to do by accident. If you can see that one product is onabotulinumtoxinA and another is abobotulinumtoxinA, you cannot mistake them for the same thing. Our unit conversion guide shows how far apart the labelled doses actually sit.
4. What the four letters on the end mean
Three of the six carry a hyphenated four-letter suffix: prabotulinumtoxinA -xvfs, daxibotulinumtoxinA -lanm, letibotulinumtoxinA -wlbg. The three older products do not.
Those suffixes are meaningless by design. They are assigned to distinguish biological products from one another without implying anything about quality, source or similarity, and they are deliberately devoid of meaning so that no manufacturer can use them as a marketing signal. You say them as letters, and in practice almost nobody does.
The practical read: a suffix marks a more recently approved biologic. It says nothing about whether the product is better, and our comparison of what the six labels claim covers what actually separates them. What each is made of is here, and which areas each is approved for is here.

Know the count before the quote. The unit count is half the bill, and a low per-unit rate recovered by a high unit count is the commonest way a deal is not one. How to tell.
