Summary
Angiotensin receptor blockers may improve insulin sensitivity and so enhance the glucose-lowering effect of insulin. This can occasionally lead to hypoglycemia, especially when the ARB is newly started.
What this interaction means in plain words
Insulin aspart and Telmisartan 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.
Insulin aspart belongs to Endocrine; Telmisartan belongs to Cardiovascular.
Why it happens
ARBs may improve insulin sensitivity, adding to insulin's glucose-lowering effect; the mechanism is not fully established.
What to do
Monitor blood glucose more frequently when starting or changing telmisartan and reduce the insulin dose if hypoglycemia occurs.
