Nalmefene is administered to these identified patients on an as-needed basis, specifically on days the patient perceives a risk of drinking alcohol, preferably 1-2 hours prior to the anticipated time of consumption. The invention targets patients with alcohol dependence as defined by DSM-IV-TR or DSM-V criteria, specifically those who are not "Early Reducers" during the observation period.
