Ozempic
Last reviewed · Written by the PepCycle team
Ozempic is the brand name for semaglutide licensed for type 2 diabetes, supplied as a multi-dose pre-filled pen and injected once weekly. It contains the same active ingredient as Wegovy but is a distinct product with its own indication, strengths and pen presentation.
What Ozempic is
Ozempic is semaglutide — a GLP-1 receptor agonist — approved for use in adults with type 2 diabetes to improve glycaemic control, with additional cardiovascular indications in some markets. It is manufactured by Novo Nordisk and administered as a subcutaneous injection once a week.
Its high public profile comes largely from off-label and cross-brand use in weight management, but its licensed indication is diabetes. Where an indication matters — insurance, clinical notes, and any conversation with a prescriber — the distinction is not cosmetic.
The dial pen and what to record
Ozempic uses a multi-dose pen: a single pen contains several weekly administrations, and the amount for each is selected on a dial before injecting. This differs from a single-dose auto-injector, where the device delivers a fixed amount and is discarded.
- Record the pen, not just the injection — which pen, when it was first used, and when it is finished. Pens have an in-use time limit after first puncture that is separate from the printed expiry.
- Record the dial setting exactly as the instructions express it. Do not convert it into millilitres or units of anything else.
- Record the needle change habit if it varies; needles are single-use by design.
- Record storage transitions — many pens move from refrigerated to room-temperature storage once in use, with a defined in-use window.
A weekly record that stays honest
Weekly medicines drift. An injection nominally on Sunday quietly becomes Monday, then Tuesday, and the interval nobody intended becomes the actual regimen. A log with real timestamps is the only thing that catches this.
- Log the actual injection time, not the scheduled one.
- Mark late and missed injections rather than deleting them — the gap is the clinically interesting part.
- Backdate honestly if you log after the fact. See logging a missed or late dose.
- Rotate and record injection sites — see injection site rotation.
- Record side effects with timestamps relative to injection day.
Ozempic and Wegovy
| Ozempic | Wegovy | |
|---|---|---|
| Active ingredient | Semaglutide | Semaglutide |
| Licensed for | Type 2 diabetes | Weight management |
| Pen type | Multi-dose dial pen | Single-dose pen presentation |
| Interchangeable? | No — separate products and labelling | No |
If you switch between them, record it as a compound change with a date rather than editing the existing record, so the history shows what you were actually taking at any point in time.
Frequently asked questions
Is Ozempic the same as Wegovy?
They share the active ingredient semaglutide but are separate products. Ozempic is licensed for type 2 diabetes with a multi-dose dial pen; Wegovy is licensed for weight management with its own presentation and strengths. They are not interchangeable.
How many injections are in one Ozempic pen?
It depends on the pen strength and the setting used, since it is a multi-dose pen. The pen's own instructions state how many administrations it delivers at a given setting — read them rather than estimating from the total contents.
Why does my log need a first-use date for the pen?
Because a pen has two dates: the printed expiry and an in-use window that begins when it is first used. Only the record you keep captures the second one, and it is the one that usually matters first.
What should I do about an injection I took two days late?
Log it with the actual date and time and mark it as late, then follow whatever your prescriber or the product's patient information says about timing. Never delete the record to make the pattern look tidier — the real interval is the useful data.
