Lisinopril
"My GP Doctor changed  my blood pressure medicine from 5mg Amlodipine Besylate/50mg Metoprolol to 5mg Lisinopril/50mg Metoprolol to protect my kidneys.  Over a forty day period my Lisinopril dosage was increased in stages from 5mg to 40mg in an attempt to get the same BP results I had with Amlodipine.  Prior to taking Lisinopril my blood pressure was around 135/75.  As the amount of Lisinopril was increased my blood pressure kept increasing. After 40 days it was around 175/85 (maximum 200/100).  I take my blood pressure 3 -4 times per day.   I experienced increased confusion, tiredness, dizziness, weakness and constipation as the dosage of Lisinopril was increased. I went back on Amlodipine and made an appointment with my Cardiologist."
