Started using Caduet in 2005. Found I got the usual side effects plus swollen ankles. Doctor changed my PX to Lisinopril about a year ago.Seemed to work well, lower BP and no side effects. About 2 months ago started getting lightheaded,nausea,and a few other side effects. Is it common to use this drug for that long and then get the side effects? How long will it take for these effects to go away if use is stopped?
