mitral valve prolapse
"I started taking 50mg of Toprol after being admitted to the hospital 6 days ago. I was told I had Mitral Valve Proplase and that I needed to take 50mg daily. It has helped in slowing my rapid heart beat down but the side effects have almost been unbearable. I have hardly slept, after taking the medicine I get short of breath and feel like I'm having an anxiety attack, and I take the medicine at bedtime. In the mornings when I wake for the first two to three hours I feel shaky, sweaty, nauseous, and extremely dizzy. My regular MD took me down to 25mg once daily and I still can't sleep and feel anxious. This is the first day taking 25mg so we'll see how I feel in the morning."
