Patient Medication Information: uses, side effects, how to take - NB-Sitagliptin

How does NB-Sitagliptin work?
NB-Sitagliptin contains the medicinal ingredient sitagliptin which belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors). NB-Sitagliptin helps to improve the levels of insulin when blood sugar level is high, especially after a meal. NB-Sitagliptin also helps to decrease the amount of sugar made by the body. NB-Sitagliptin is unlikely to cause low blood sugar (hypoglycemia).
