Is metformin usually tried before a GLP-1 medication for type 2 diabetes, or do they get prescribed together?

Metformin has traditionally been a common first-line medication for type 2 diabetes, but current practice increasingly involves prescribing a GLP-1 medication either alongside metformin or, depending on the individual's health profile (like existing cardiovascular risk), sometimes earlier in treatment rather than strictly after metformin. It's less of a rigid "try this first" sequence than it used to be and more based on the individual's overall risk profile.
