4 doctors weighed in:

How long does ativan (lorazepam) last? I'm prescribed one .5 twice a day as needed and I don't take often but it seems like it's not effective. Still anxious.

In brief: Ativan (lorazepam)

Depending on the extent of the anxiety, it can last from 4 to 6 hours, but I recommend discussing with your doctor to see if any adjustments would help.
