DPP-4 inhibitors have no relevant drug-drug interactions or contraindications.

DPP-4 inhibitors have no relevant drug-drug interactions or contraindications.

• A. True
• B. False
• C. Unknown
• D. Not documented

Answer: (A)

DPP-4 inhibitors have drug interactions and contraindications. They’re not completely free of interactions, and certain safety considerations matter in clinical use. Some require dose adjustments in kidney disease (sitagliptin and alogliptin need renal-based dosing changes; linagliptin is largely excreted non-renal, so usually doesn’t need renal dose adjustment). Saxagliptin is processed by CYP3A4, so strong inhibitors or inducers of this enzyme can raise or lower its levels and effects. There’s also a recognized warning about an increased risk of heart failure hospitalization with saxagliptin in patients with or at risk for heart failure. All DPP-4 inhibitors carry a potential risk of pancreatitis, and severe hypersensitivity reactions can occur, though rarely. When used with insulin or a sulfonylurea, there’s a higher chance of hypoglycemia, so monitoring and dose adjustments are important. So the statement that there are no relevant drug-drug interactions or contraindications isn’t accurate.
