Last week I read something on this site about heart problems using domperidone. They were seeing a cardiologist to have there QT checked. I'm not sure what that is but I am curious if anyone out there using domperidone knows of this or has had any problems with it. I am so uneasy taking this drug that I give myself anxiety attacks thinking about it. I've been on it for 7 weeks now and to be honest I don't know if it is doing much good. How long does it take to notice any improvement?
