A. “This medication helps lower my blood sugar by increasing insulin release.": Sitagliptin (Januvia) works by increasing insulin release and decreasing glucagon levels when blood glucose is elevated, helping to lower blood sugar. B. "I need to keep monitoring my blood sugar regularly while on this medication.": Regular monitoring of blood glucose levels is important to ensure the medication is working effectively and to detect any changes in blood sugar. C. "I will call my provider if I develop severe abdominal pain that doesn't go away.": Severe abdominal pain can be a sign of a serious side effect such as pancreatitis, and the client should contact their healthcare provider immediately if this occurs. D. "If I feel nauseated or vomit after taking this drug, I should just wait and see if it gets better.": Nausea and vomiting can be side effects of sitagliptin. If the client experiences these symptoms, they should not simply wait, but instead contact their provider for further guidance, as these symptoms may require adjustments to the treatment plan.
