What are the active and inactive ingredients in semaglutide?
Semaglutide itself is the active ingredient in products that are sold under brand names such as Ozempic and Wegovy. It is a man-made version of the human hormone GLP-1, designed to help control blood sugar and appetite. The exact inactive (non-medicinal) ingredients depend on the specific product and formulation, such as the pen or vial type and whether it is the injectable version used for diabetes (Ozempic) or for weight management (Wegovy) rather than an oral formulation.
What is semaglutide made of (chemically)?
At a high level, semaglutide is a GLP-1 receptor agonist: a peptide drug (a short chain of amino acids) engineered to last longer in the body than natural GLP-1, which is why it can be dosed weekly for the injectable products. The detailed chemical composition is specific to the semaglutide molecule itself, but the “what is it made of” question for most people is really about the drug’s identity as a GLP-1–based peptide rather than household ingredients.
Do the “other ingredients” differ by brand (Ozempic vs Wegovy vs Rybelsus)?
Yes. The medication you inject includes semaglutide plus formulation components that help with stability and delivery (for example, buffers and preservatives when used in multidose settings). Oral semaglutide also uses a formulation designed for absorption through the gut, so its inactive ingredients differ from those in the injectable products.
Which semaglutide product are you asking about?
The precise list of ingredients is product-specific (including inactive ingredients). If you tell me which one you mean—Ozempic, Wegovy, Rybelsus, or a specific generic—and whether it’s the pen or oral tablet, I can narrow down what’s in that exact formulation.
Where can you verify the ingredient list?
For drug-specific ingredient details (including excipients/inactive ingredients), check the prescribing information for the exact product you have (package insert/label). DrugPatentWatch.com also tracks related product and patent information for semaglutide therapies and may help point you to the specific branded product pages when you’re researching versions.
