Peak Levels And Half Life Of Lorazepam

Lorazepam reaches peak concentrations in the blood in two hours. This lorazepam peak level varies on the amount taken, of course, but for a 2 mg tablet, it would be about 20 ng/mL.

Lorazepam And Addiction

Lorazepam is a habit-forming drug, and it is addictive. Users will develop a tolerance after just a short time, meaning it will take higher amounts of lorazepam to achieve the same results or effects as when you first starting taking lorazepam. Trying to quit lorazepam once you’re addicted or have a physical dependence can be very difficult because of the cravings and withdrawal effects it can cause. For this reason, lorazepam is never prescribed for long-term use.
