Every Ozempic pen delivers four once-weekly doses, about one month at its labeled strength. How the pens count out, and when to discard a pen.
Key points
- 01Every Ozempic pen holds four weekly doses. The Novo Nordisk prescribing information describes each Ozempic pen as a supply of four once-weekly injections, about one month, at the strength printed on the label. One pen covers a single dose level, not several.
- 02Three pen strengths, each counting to four doses. Ozempic comes as a 0.25/0.5 mg pen (2 mg in 1.5 mL), a 1 mg pen (4 mg in 3 mL), and a 2 mg pen (8 mg in 3 mL). Each pen is engineered so the dose counter reaches the full dose exactly four times.
- 03The starter pen covers one dose level at a time. The 0.25/0.5 mg pen delivers four 0.25 mg doses in month one. To step up to 0.5 mg you start a fresh pen of the same type set to 0.5 mg. This keeps the fixed four-doses-per-pen rhythm intact.
- 04The dose counter signals empty, not the liquid line. Some liquid always stays behind, a deliberate overfill. Rely on the dose counter and the clicks while dialing, not the visible remainder. The Ozempic click chart shows how many clicks match each dose.
- 05A pen lasts about 28 days, but a discard window also applies. Four weekly doses run about 28 days. Regardless of doses left, the prescribing information describes discarding the pen 56 days after first use. The guide on whether Ozempic needs to be refrigerated explains that window.
- 06If it will not dial a full dose, the pen is empty or faulty. When the dose counter will not turn to the full dose, the four doses are used up or the pen is not working correctly. The guide on an Ozempic pen that will not work walks through the checks.
