Tizanidine
"This was prescribed for spasms but I found it also lowers my bp. My bp and heart rate has been crazy over 5 yrs. At times my bp too low & heart rate too high. Top too low, bottom high. A lot of the beta blocker & channel blockers would drop my bp too low too fast. I couldn't be on any of them regular cuz of this so I just use tiz. To lower my pressure & at night to sleep at times but seems give me nightmares & depression. Also my mom takes it at night & it lowers her bp & knocks her out. She doesn't move all night. "
