What to expect at a Physician Assistant visit

Physician assistants deliver care and prescribe in collaboration with a supervising physician. A GLP-1-related visit generally involves:

  • •A health and medication review with the collaborating practice's protocols in mind.
  • •Screening labs where indicated before starting therapy.
  • •A discussion of GLP-1 options and next steps.
  • •Follow-up for dose titration and monitoring.
