Lisinopril
"I am in my early 40's.  I was prescribed Lisinopril (10mg) to treat high blood pressure.  After a subsequent visit to my doctor, it was determined that 10mg was not dropping my blood pressure and he prescribed 20mg.  This has caused a mild side effect of a constant dry cough and unfortunately, it did not drop my blood pressure either.  I am now taking AMLODIPINE BESYLATE but just started it so I don't have enough history with it to tell if it will work."
