Dosage: 10 mg/day-swelling of affected foot and ankle, heart arrhythmia, skin rash, sensation of skin burning, exhaustion, falling asleep in the middle of a task at noon. Originally prescribed by a general practioner after a hemorrhagic stroke in order to lower BP. A neurologist recommended doubling the dosage. I discontinued lisinopril (also had to discontinue toprol prior to being put on lisinopril because of extremely low pulse rate - under 40 bpm). I use no drugs and am using low sodium, high fiber diet to lose weight and control BP.
