I'm on. 5 mg of ativan (lorazepam) daily. Can I just go off it? Also how long does it stay in my system if I wanted to have a drink? Been on it for a year.

Do NOT stop w/o Doc. It is usually recommended not to use this drug for longer than 4 months without clear reasons. It is always recommended that the drug be tapered with the help of a physician. Ask that physician to tell you when you might be safe to have any alcohol. The risk seems to be that the combo will be dangerously much stronger. So, if & when you do drink - have very low proof & a very small amount. Best!
Ativan (lorazepam) Although a low dose, it is wise to taper the dose, under your doctor's supervision, and continue behavior therapy to help with your depression/anxiety. Wish you well.
