A

Use caution with these pts.

Xultophy is Contra-indicated in pts have hypersensitivity rxns to deg, lira, or excipients.

47
Q

Why is there a caution about hypokalemia?

A

All insulin products can cause shift in K from extra to intracellular space – which can lead to hypokalemia (respiratory paralysis, ventricular arrhythmia, death).

Monitor K levels in pts at risk for hypoKalemia.

Does Xultophy cause fluid retention?

A

No, but other products can cause fluid retention if used with insulin: PPAR - gamma agonist.
