SEMAGLUTIDE (SEM a GLOO tide) treats type 2 diabetes. It works by increasing insulin levels in your body, which decreases your blood sugar (glucose). It also reduces the amount of sugar released into the blood and slows down your digestion. It can also be used to lower the risk of heart attack and stroke in people with type 2 diabetes. Changes to diet and exercise are often combined with this medication.
