Lisinopril
"I've been taking Lisinopril (5mg) daily for 1-1/2 years, as prescribed by my primary care physicial, to lower my blood pressure.   I initlally experienced a persistent, dry cough, which the pharmacist that filled the prescription warned me about, but found that by drinking more water, I was able to eliminate the cough.  Aside from the cough, there have been no other adverse side effects associated with taking Lisinopril, and my blood pressure is now within a normal healthy range."
