A member asked:

I know it starts working quickly, but how long does .5 lorazepam generally work for?

3 doctors weighed in across 2 answers

6-8 hours: Ativan (lorazepam) peaks at about 2 hours if taken orally. The drug will last about 6 to 8 hours but the drug will be in your system for longer period if time. If you have kidney dysfunction then it can last longer. Make sure not to drink alcohol with this medication.
