high blood pressure
"I am a 30 year old female and I have high blood pressure (and tachycardia). Approximately 20 minutes or so after I would take my dose of Lopressor, I would get symptoms similar to a panic attack. Extreme hot flash and rapid heartbeat (more rapid than my usual... my pulse rate is usually around 100-105 as it is.) When I told my doctor, he told me to quit taking the Lopressor and then he put me on another high blood pressure medicine. I only took Lopressor for a few days, because of the side effects, so I cannot comment on it's effectiveness in blood pressure reduction."
