Hi, Please talk to your wife s doctor, preferably in her absence, and inform him about the euphoric effects as well as her heavy alcohol intake. Since Suboxone is a controlled drug and cannot be prescribed without any specific indication, please ask her doctor why she has been prescribed this and how long does he intend to continue the prescription. Most commonly it is prescribed to people on intravenous opioids like heroin who are unwilling to quit, in order to reduce the harm and risks associated with intravenous drug abuse. Even if your wife was prescribed Suboxone for this indication, if she is getting too high, then the doctor can reduce the dose. Heavy alcohol intake while on Suboxone may be dangerous as there is a risk of respiratory depression and seizures. Her doctor must be informed about this. Hope this helps you. Best wishes.
