High Blood Pressure
"Have been taking Zestril for many years, starting with 20 mg, and last year the doctor increased to 40 mg. Have had no noticeable side effects, and it controlled my pressure for many years prior to last year.  I am 75 years old now, so I suppose it is normal to need an increased dosage.  The doctor also added Cardizen CD last year, as I had an episode of rapid heartbeat (over 200bpm) while in his office, and he sent me to the ER.  Since taking Cardizem CD for more than a year, I have had no repeat episodes.  No noticeable side effects either."
