Direct answer: The U.S. Ozempic pen containing 4 mg in 3 mL is labeled to deliver four 1 mg doses. The 4 mg figure is the total amount in the pen, not the amount in each injection. Novo Nordisk says to read the dose counter and pointer and not to set the dose by counting clicks.
4 mg total versus the selected dose
These numbers describe different things: 4 mg is the pen's total semaglutide content, 3 mL is its solution volume, and 1 mg is the labeled amount selected for each dose from this presentation. The current U.S. prescribing information lists the 4 mg/3 mL pen as four 1 mg doses.
How the U.S. Ozempic pens differ
| Pen label | Total contents | Labeled selectable dose |
|---|---|---|
| 0.25 mg or 0.5 mg | 2 mg in 3 mL | 0.25 mg or 0.5 mg |
| 1 mg | 4 mg in 3 mL | 1 mg |
| 2 mg | 8 mg in 3 mL | 2 mg |
The comparison is specific to the U.S. multi-dose pens described in Novo Nordisk's current U.S. prescribing information and Instructions for Use. The total amount printed on a pen is not its per-injection dose.
Why a click count does not show the dose
The pen instructions identify the dose counter and pointer as the way to see the selected amount. They explicitly say not to set the dose by counting clicks. The selector can make sounds as it turns, but Novo's instructions do not define a universal click-to-milligram conversion. A chart claiming a fixed number of clicks for 1 mg is not a manufacturer-supported dose chart.

Does a 4 mg Ozempic pen deliver 4 mg in one injection?
No. For the U.S. 4 mg/3 mL pen, 4 mg is the total pen content; the labeled amount is 1 mg per dose, for four labeled doses.
How many clicks are 1 mg on this pen?
Novo Nordisk's Instructions for Use say to use the dose counter and not to set a dose by counting clicks. They do not provide a supported click count for 1 mg.
Does the same total amount mean the same selected dose on every Ozempic pen?
No. The U.S. presentations have different total contents and labeled dose settings. Match the pen label to its own Instructions for Use.
