Semaglutide 7 mg (Rybelsus) is the first maintenance oral dose used with diet and exercise to improve blood sugar control in adults with type 2 diabetes after starting at 3 mg for 30 days. After at least 30 days on 7 mg, some patients may be increased to 14 mg if more A1C lowering is needed. It works by boosting insulin release after meals, reducing liver glucose output, and slowing gastric emptying.
