I have experienced many of the side effects I have found on this site. Head and neck sweating, waking in the middle of the night with difficulty breathing, fatigue!!!!! to the point where I have to take naps in the afternoon!!..I am only 43. Has anyone experienced hair loss? I have a significant head of hair...or I did have. It is coming out in handfuls now. I am on 20mg of Lisinopril recently increased from 10mg. The hair loss began with the lower dosage.
