Summary
HIV protease inhibitors can cause insulin resistance and hyperglycemia, which may reduce the glucose-lowering effect of insulin glargine and lixisenatide. Glycemic control may worsen, particularly early in treatment.
What this interaction means in plain words
Fosamprenavir and Insulin glargine-lixisenatide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Protease inhibitors impair insulin-mediated glucose uptake, partly through effects on GLUT4, causing insulin resistance.
What to do
Monitor blood glucose and HbA1c when starting or changing the protease inhibitor and increase antidiabetic doses as needed.
