I was on Lisinopril for about 3 1/2 months. I coughed the entire time-day & night. I coughed until I vomited almost daily. I had diarrhea, severe muscle cramps in my sides and toes. The coughing was HORRIBLE and I really thougth it was going to kill me. I saw a new doctor who told me Lisinopril is notorious for causing coughs. My first doctor told me to take Mucinex. He is a moron. Thank God I changed doctors. It took an additional 16-17 days for the cough to subside once I stopped taking Lisinopril. Now I am taking Norvasc 10MG. It makes my ankles swell. Not thrilled with it but I could not cough another day.
