high blood pressure
"For the past 18 months, I have experienced labile hypertension of unknown cause evidently unrelated to any underlying condition or risk factor. Coreg CR which I have been taking for approximately two months has provided great benefit in stabilizing my surges (from 100/50 to 200/100 in less than two hours). It is a beta blocker and provides some vasodilation.

Side effects to date include some shortness of breath, which reduces over time, and some dizziness and drowsiness/hypotension approximately 6 hours after administration. Taking 40 mg extended release form along with calcium channel blocker, clonidine patch, and diuretics."
