high blood pressure
"Was on Toprol for a long time and was having to constantly increase the dosage.  My doctor switched me to this and I immediately noted a great balance of blood pressure.  Went from 145/98 to 127/78 (ish).  Only side effects I have noted are ones that are easily cured with water intake. I get the cough and am lethargic and dizzy when working in the yard (I live in Texas so it's a billion degrees outside).  Both of these however are mitigated with increased water intake.  I drink flavored water throughout the day and these side effects have subsided.  Very happy with this medicine."
