Thank you for asking. Amixide is not good for heart. It is not indicated in heart condition. Therefore, I would suggest not to take that tablet. For your problem of insomnia, there are various cradio safe medicines available. Initially for the treatment to set in, it will take some time. You will need to consult a psychiatrist for this issue, follow his treatment for substantial period. There are drugs available with similar property as that of Amixide but with cardiac safe profile.
Next Steps
Kindly consult with a psychiatrist a bit your problem.
