Rybelsus 14 mg regulates blood sugar levels by replicating the effect of a natural hormone in the body called GLP-1. GLP-1 is produced in response to meal consumption and regulates blood sugar levels by enhancing insulin production, lowering glucagon secretion, and delaying stomach emptying. Rybelsus 14 mg works by raising GLP-1 levels in the body, which helps to reduce blood sugar levels. It is vital to take Rybelsus 14 mg as advised by your doctor, generally once daily, with a sip of plain water, and wait at least 30 minutes before eating or drinking anything other than plain water, or before taking any other prescription orally.
