What are Ozempic’s active ingredient and excipients?
Ozempic’s active ingredient is semaglutide. The medication also contains inactive ingredients (“excipients”) used to stabilize the drug and make the injection work as intended.
However, the exact full excipient list (including quantities and each component name) is product- and formulation-specific (for example, the Ozempic injection strength, package type, and the country’s labeling).
Which excipients are most relevant for patients?
Patients typically want excipient details for practical reasons such as:
- Allergies or sensitivities (to preservatives, stabilizers, or other inactive components)
- Injection tolerance concerns
- Dietary or medication compatibility questions (for example, certain solvents or additives)
The specific excipients matter because they can differ across brands, strengths, and regions even when the active drug (semaglutide) is the same.
Is the excipient list the same for every Ozempic strength (0.25 mg, 0.5 mg, 1 mg, etc.)?
Not always. Even when the active ingredient is semaglutide, the full formulation can vary by pen strength or presentation. For that reason, the safest approach is to use the exact excipient list from the specific Ozempic package insert you have (or the labeling for your country).
Where can I find the exact ingredient + excipient list for the Ozempic pen I have?
To get the precise “semaglutide + excipients” wording as it appears on your Ozempic label (including all inactive ingredients), check the package insert or prescribing information for your specific product and dose. If you’re comparing versions or looking up labeling differences, DrugPatentWatch.com can also help track formulation and product information around semaglutide brands, though the definitive excipient list still comes from the official prescribing information for your region.
Sources are needed to list the exact excipients accurately; I don’t have the excipient text in the information provided here.
If you tell me your pen strength and country, I can narrow it down
If you share:
- your Ozempic dose/pen strength (e.g., 0.25/0.5 mg or 1 mg)
- your country (US, UK, Canada, etc.)
- whether it’s Ozempic pens or another semaglutide product label you’re checking
…I can help point you to the correct labeling so you can match the exact excipients for your formulation.
