Summary

What this interaction means in plain words
Insulin isophane human / insulin regular human 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.
Why it happens
Additive pharmacodynamic effect, probably through improved insulin sensitivity with ARBs.
What to do
Check blood glucose more often when telmisartan is introduced or stopped. Reduce the insulin dose if hypoglycemia develops.
