What is the difference between oral and injectable GLP-1 medicines?

These medicines come in more than one form. Some are given as an injection, often weekly, and others are taken by mouth. The route changes how the medicine is absorbed, which is why a tablet form and an injectable form of the same medicine are not interchangeable and are not prescribed at the same numbers.

This is the source of a lot of confusion online. Milligram strengths from one product get compared with strengths from another as though a larger number means a stronger treatment, when the two are not on the same scale at all. Comparing them that way is meaningless.

Which route suits you depends on things a page cannot see: whether you can take tablets with the timing they require, whether injecting is workable for you, and what else you are being treated for. That is a conversation with a prescriber, and the leaflet for whichever product you are given is the authority on how it is taken.
