high blood pressure
"I have not liked this medication at all.  I was taking 25 mg of Hydrochlorothiazide, which worked great to reduce and maintain my blood pressure, but a side effect was frequent urination, and as a teacher, that was a slight nuisance.  However, with generic Toprol, I have not gotten a decent night's sleep, and my blood pressure went higher (although I halved the 25 mg pill due to the side effects).  I also feel anxious and unsettled. "
