Semaglutide does not significantly increase the risk of hypoglycemia in patients not using concomitant insulin or sulfonylureas, due to its glucose-dependent mechanism of action.

You don't need to worry about your blood sugar dropping dangerously low while taking semaglutide by itself. It works gently with your body's natural processes. However, if you are also taking insulin or sulfonylureas, your risk of low blood sugar increases, so your doctor may lower the dose of those other medications.

StrongRefutesVERY_HIGH confidence
since GLP-1RA mainly lower blood glucose by stimulating glucose-dependent insulin secretion, hypoglycemia is an infrequent problem... In SUSTAIN-6, severe or plasma glucose-confirmed (<56 mg/dl) hypoglycemia occurred in similar rates between patients with semaglutide... and placebo
