How Many Doses Are in a Wegovy Pen?

Wegovy (semaglutide) is supplied as a pre-filled, single-use pen. Each pen is designed to deliver one subcutaneous injection, and once that injection has been given the pen is discarded. There is no reloading or re-use involved.

Dose strengths and titration

Wegovy is available in several dose strengths. According to the electronic Medicines Compendium (eMC), the strengths commonly used during the titration schedule are 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg. Your prescriber decides which strength is appropriate for you at each stage — the schedule typically starts low and increases gradually over a number of months. Each box of Wegovy pens contains the pens for a set period of treatment, but the number of pens per box can vary depending on the strength and pack size; check the leaflet that came with your prescription for the exact count in your pack.

Why this matters for staying on track

Because each pen holds only one dose, keeping count of how many pens you have left is straightforward — but it is easy to lose track of which dose you administered and when, especially as strengths change across titration stages. That is where logging each injection becomes genuinely useful.

If you are curious about how pen supply works for other GLP-1 medicines, it is worth understanding how many doses a Mounjaro pen contains, which follows a similar single-dose-per-pen principle. You can also read more about Wegovy pen doses and what to expect at each stage for a broader overview of the titration journey.

Knowing that each pen equals one dose is simple in theory — but across months of weekly injections and changing strengths, it is easy to lose track of exactly which dose you took and when. GLP Trackr's dose logging feature is built precisely for this.

Each time you inject, you can log the date, time, and dose strength in the app. Over time, this builds a clear, timestamped record of every injection — useful if you ever need to check when your last dose was, or if you want to bring an accurate summary to a conversation with your prescriber.

The app also lets you set a weekly dose reminder, so you are less likely to accidentally miss a scheduled injection. And if a dose is missed, you can log that too — creating an honest record to discuss with your healthcare professional rather than guessing later.

For those also interested in how dosing compares across GLP-1 pens, you might find it helpful to explore how many doses per pen Mounjaro provides, or visit the Mounjaro dosing overview for broader context on titration schedules.

Any decision about your dose, timing, or titration stage should always be made with your prescriber — never independently. If you have questions about your current strength or schedule, contact your healthcare professional directly.
