I started taking Benazepril (a generic for Lotensin) starting about a week ago, instead of Accupril. Today for the first time in a long time I felt pretty good with no headache I always kinda associated with the Accupril. I realize these are all the same family (ACE inhibiters) but do you think a change within the family could produce fewer side effects. Accupril always produced "the cough" and headache I think.
