High Blood Pressure
"I used lisinopril for about 10 years for hypertension secondary to polycystic kidney disease.  Most of that time I spent at a 20mg dose and had an occasional dry cough, usually at night.  However, it controlled my blood pressure well for most of that time and the cough wasn&#039;t persistent.  We recently increased my dose to 30mg and I immediately developed a severe and persistent dry cough.  It was so bad that I was taking two doses of Nyquil a night (once at bedtime, once ~4am) to subdue the cough and get to sleep.  So, we discontinued the lisinopril."
