Lisinopril and vocal chords

I have been taking Lisinopril for 7 months. The cough started after 2 weeks, so I went to a doctor thinking I hada strange kind of flu. I sometimes can´t speak after coughing, seems that my vocal chords have an irritation. This doctor prescribed me antibiotics, as it seemed that I was experiencing some kind of pneumonia. I was fine for 2 weeks, but again I began with the dry coughing, specially at night and when running a little. After I visited my Cardiologist, he told me that my cough was a reaction to Lisinopril, so now he has prescribed me another medicine.
