Does anyone know if you can develope bad side effects to a medication you have been taking for over 2 years? I have been taking lisinopril for high blood pressure and a few weeks ago I started to have all the symptons which I am going to the dr for but after finding a site on lisinopril I see that many people are having the same problem as I. Could after 2 years on the meds could I suddenly be developing a reaction to the med? Any info would be helpful.
