high blood pressure
"I have tried the generic version (extended release) after using brand name Toprol XL.  The generic did not work well for me. After a few days it felt like I hadn't taken the medicine. Toprol XL works great, and when i swapped back to the original I felt great again. There must be some difference in the release between the two. This med brings the BP into 120's over low to mid 70's range where I was reg 140's/90's. It also helps bpm from mid 90's down to upper 70's."
