Is this semaglutide 1mg product available as a tablet, or only as an injection?

This particular semaglutide 1mg product comes as an injectable solution in a pre-filled pen, not as a tablet. It's meant to be injected under the skin, usually once a week, and the pen is designed to make that fairly simple to do at home. If you'd prefer an oral option, do ask your doctor, since semaglutide tablets exist too but are a completely separate product with different dosing.
