How many doses does one Wegovy pen contain?

Why does each standard pen contain four doses, not more?

Novo Nordisk designed the standard Wegovy pen as a one-month supply matched to the titration rhythm. You inject once weekly, work through four doses, and the pen is finished. There is no fifth dose sitting unused inside, the pen is engineered to deliver exactly four full injections, after which the mechanism locks.

This matters practically. If your prescription covers one pen per month, you will use the last dose on roughly the same day of the week each month. Planning your reorder around that rhythm means you will not find yourself mid-titration without a pen. Our prescribers review every repeat order before it is dispensed, so building a few days' buffer into your reorder timing is worth doing, the full Wegovy guide explains what that review covers.

One misconception worth clearing up gently: some people assume a larger, heavier pen must contain more doses. It does not. If you want to understand how many doses are in a standard Wegovy pen and why the count stays consistent across the range, that page explains the engineering behind it. All standard strengths deliver exactly four.

The NHS semaglutide medicines page confirms that Wegovy is injected once a week and describes the general supply format for patients unfamiliar with self-injection devices.

What changed when the 7.2 mg pen was approved?

The MHRA approved the dedicated 7.2 mg single-dose pen on 14 April 2026, and the format is genuinely different from the pens used at every lower strength. Rather than one pen covering four weeks, the 7.2 mg pen delivers one injection and is then discarded. To cover a full month at 7.2 mg, a patient needs four individual pens.

The pen itself has a built-in covered needle and locks automatically after use, which addresses some of the handling questions that came up when the 7.2 mg dose was first introduced in early 2026 as three separate 2.4 mg pens administered in a single week. The dedicated pen simplifies that considerably.

It is worth noting that the 7.2 mg approval is specifically for adults with a BMI of 30 or above. The starting dose remains 0.25 mg regardless of which maintenance strength a patient eventually reaches, and the titration steps (each lasting roughly four weeks) are managed by the prescriber. If you are curious about how the full Wegovy dose schedule is structured from start to finish, that page walks through each step.

For detail on how the 7.2 mg format compares in terms of weight-loss results, the MHRA's announcement of the single-dose pen approval sets out the clinical rationale and the licensed indication clearly.

Does the number of doses affect how you store or travel with a Wegovy pen?

Knowing that a standard pen holds four doses has a direct bearing on storage. Once you start using a pen, it stays in use for four weeks, and for the duration, it needs to be kept refrigerated between 2°C and 8°C when not in use. You cannot pre-dose or transfer semaglutide to another container. The pen you open is the pen you finish.

For travel, the practical consideration is that a part-used pen still holds whichever doses remain in that monthly supply. The exact window during which Wegovy may be kept at room temperature is specified in the Patient Information Leaflet; always refer to that rather than general guidance, because the window differs between products and storage conditions. The frequently asked questions page covers common storage queries if you want a quick reference.

If you are considering what your monthly supply costs alongside these practical details, the Wegovy cost and pricing page explains what a private prescription typically includes and what to check before comparing providers.

Does the dose count change if you are on a different strength mid-titration?

No. Whether you are on the 0.25 mg starter pen, which contains four doses just like the others, or the 1.7 mg pen that precedes the standard 2.4 mg maintenance dose and also holds four doses, the count stays the same: four doses per pen, one pen per month. The only exception, as above, is the 7.2 mg single-dose pen.

This consistency is useful when you are planning repeat orders. Your prescriber will confirm which strength comes next before any new supply is issued, at nume, that clinical review happens before every repeat, not just at the start of treatment. If you have questions about your specific supply timing or want to understand your titration plan in more detail, our support team is available seven days a week.

Wegovy is a prescription-only medicine; a prescriber (not an algorithm) assesses your case before supply is authorised. If you would like to understand whether Wegovy could be a suitable option for your circumstances, you can check your eligibility with a free consultation.
