Dexamfetamine, and related drugs such as ecstasy, may reduce the deleterious effects of alcohol

may increase the cardiac adverse effects of amfetamines
The effects of this interaction are not clear, but as some psychomotor impairment occurs warn all patients of the potential effects, and counsel against driving or undertaking other skilled tasks.
