I started Lisinopril a 6 weeks ago at the suggestion of my Internist. The blood pressure medicine I was on (for 5 years) was too strong and causing me to have episodes of dizziness and hypotension. Since starting Lisinopril I have suffered with a severe hacking cough that is especially troublesome at night. It wakes me up almost every night and I wind up sleeping in an upright position on my lazy boy and taking strong cough medicine to suppress it. Since I am an RN, I attributed this to climate, my job (with children), and generalized stress of graduate school/work/family. I have a call into my Internist and will stop Lisinopril immediately. Thank you for this blog.
