Type 2 diabetes mellitus is a prevalent disease and concern worldwide. Along with its associated side effects, diabetes remains the seventh leading cause of mortality in the United States.
Given its heavy prevalence, the chances that you’ll encounter a diabetic patient in your exam chair are extremely high, regardless of the demographic or population of the area you practice in. Here is a summary of common drugs you will encounter with your diabetic patients.
Your knowledge of these agents, even when your patients forget what drugs they're taking, will not only solidify your skills as a clinician but will also help build better rapport with your patients.
