mitral valve prolapse
"Been on it for 5 yrs. Keeps my blood pressure and mitral valve prolapse under control. Have to take it every 12 hours. Can't go an hour past time or my body knows. I guess you can say that is a not so good thing. But, my symptoms are in check. Refuse to use an alternative medication. The downside to using beta blockers is the side effect. I break out with eczema and psoriasis, these are the biggest problem with this medication, but there are medications that keeps that under control as well."
