I took 7mgs or 14mgs (small white pill) of ativan (lorazepam) over a 4 day span. My last dose was the 27 february how long before undetectable in urine?
HIGH Ativan (lorazepam) doses. Your Ativan (lorazepam) quantity has changed since your last message, but the time required for eliminating it from your body is still the same: at least 100 hours from last dose. If you're taking 7-14 mg of Ativan (lorazepam) that is not prescribed for you, this still sounds like substance abuse with tolerance to ativan (lorazepam). Your doctor is a good resource for help with this problem.
