The short answer
Four in most pens: four 1 mg doses, or four 2 mg doses. The starting pen holds four 0.25 mg doses and two 0.5 mg doses, or four 0.5 mg doses. Once started, a pen is thrown away after 56 days.
What the label says
The Ozempic pen is a multidose pen: one pen, several weekly shots. The dosage forms section of the prescribing information gives the count for each one:
From the labelInjection: 2 mg/3 mL (0.68 mg/mL) for 4 doses of 0.25 mg and 2 doses of 0.5 mg or 4 doses of 0.5 mg, 4 mg/3 mL (1.34 mg/mL) for 4 doses of 1 mg, and 8 mg/3 mL (2.68 mg/mL) for 4 doses of 2 mg in single-patient-use pens
The Instructions for Use for the starting pen repeat it in plain words:
From the labelEach prefilled pen contains 4 doses of 0.25 mg and 2 doses of 0.5 mg or contains 4 doses of 0.5 mg.
The carton holds the needles to go with it, according to §16: six NovoFine Plus needles with the starting pen, four with the 1 mg and 2 mg pens. The Instructions for Use ask for a new needle for each injection.
Why the starting pen is different
The first pen follows the dose steps of §2.2: 0.25 mg once a week for 4 weeks, then 0.5 mg. Four doses of 0.25 mg and two of 0.5 mg make the 2 mg the pen holds, so the first pen covers the first six weeks. If 0.5 mg is your dose for the longer run, the same pen gives four doses of 0.5 mg. From 1 mg up, every pen is four weekly doses, so about a month.
The rules that end a pen
A pen is finished for one of two reasons, whichever comes first.
The first is the dose counter. The Instructions for Use explain how to see what is left, and what to do when it is not enough:
From the labelIf there is not enough OZEMPIC left in your pen for a full dose, do not use it. Use a new OZEMPIC pen.
They are also clear about trying to collect the remainder:
From the labelNever use a syringe to withdraw OZEMPIC from your pen.
The second is time. An unused pen stays in the refrigerator until its expiration date. Once you have used it, the clock starts:
From the labelThe OZEMPIC pen you are using should be disposed of (thrown away) after 56 days, even if it still has OZEMPIC left in it.
For four weekly doses, 56 days leaves room for a late week or two. It is the limit, not the plan.
The first use of each new pen
Each new pen starts with a flow check, which the Instructions for Use describe step by step:
From the labelCheck the OZEMPIC flow before the first injection with each new pen only.
The reason is given in the same document: if no drop appears, the shot does not happen, even though the counter turns.
From the labelIf no drop appears, you will not inject any OZEMPIC, even though the dose counter may move.
Follow the Instructions for Use that came with your pen; they differ slightly between the 0.25/0.5 mg, 1 mg and 2 mg pens.
What people actually do
In tracker app reviews and forum threads about weekly shots, the practical questions come back to the same two: where the last shot went, and how many doses or refills are left before the next pharmacy trip. Some people also lean on the pen colour to recognise their dose.
Oolite logs each shot with its dose, so the four shots of a pen are four dated lines in your history and in the report for your prescriber.
Questions people ask
Why does the starting pen have six doses?
It matches the label's first steps: 0.25 mg once a week for 4 weeks, then 0.5 mg. Four doses of 0.25 mg and two of 0.5 mg add up to the 2 mg the pen contains. If you stay on 0.5 mg, the same pen gives four doses of 0.5 mg.
Can I get one more dose out of what is left?
The Instructions for Use say no. If the dose counter stops before your dose, there is not enough for a full dose and you use a new pen. They also say never to draw medicine out of the pen with a syringe, and to throw the pen away after 56 days even if some is left.
Do I check the flow every week?
Only before the first injection with each new pen. The Instructions for Use add one exception: if you drop the pen or suspect a problem, attach a new needle and check the flow again before you inject.
Is there an Ozempic with one dose per device?
Since the 05/2026 revision, the label lists single dose prefilled syringes of 0.25 mg, 0.5 mg and 1 mg, in cartons of four. There is no 2 mg syringe.
