Amlodipine
"I started Amolodopine/Besylate in August of 2011.  I switch from lisinopril as I was having severe allergic reactions.  Now I'm on this new medication and I have been feeling unusual at times.  I feel very dizzy, swelling in hands, feet and throat area.  I've had a throat infection and sometimes I feel like I'm limited in my speech.  I'm experiencing tingling in my hands and feet at times.  It's annoying.  My blood pressure is lowering now because I've increased my exercise, but sometimes I'm not able to drive home because of the dizziness.  I've had one crazy episode when I took a multivitamin.  I felt my heart beating so fast and I could literally hear it through my ears.  I was unable to pay attention and was jittery and cold."
