Carvedilol
"I've been on carvedilol for 6 months, in conjunction with lisinopril, and it has worked well on lowering my blood pressure, where the lisinopril alone was barely fazing it. With no medicines my pressure was running around 200s/120s, on lisinopril alone it was only coming down to 180s/100s. Since being on carvedilol, it runs (in my opinion) a almost too low, around 90s to low 100s over 50s. This doesn't bother me so much, but occasionally, and for no reason I determine, it will either spike or plummet. It has been as high as 180/98 and as low as 86/38. THAT was scary. I also have nausea, dizziness upon standing or moving very suddenly, and nearly disabling headaches. I like what it does for my blood pressure, but not how it makes me feel."
