I started taking Lisinopril 6 days ago. About 3 days into it, I felt like I was coming down with something like the flu. I had fever, chills, body aches and an overall feeling of just feeling awful! I developed a sore throat and a cough. I did not associate it with Lisinopril until I got online and read that a serious side effect could be fever, chills and flu like symptoms! Today, I can hardly talk, my throat is so sore. Needless to say, I won't be taking any more Lisinopril!
