I worked in a hospital before. ER docs are not allowed to perscribe medicine like a primary care doc would. You would need to call your regular doc and ask if he can write a script and let you pick it up if you can't get in for another two weeks
They gave me a shot of Ativan that took only the edge off my anxiety and than pretty much kicked me out of the hospital. I understand they have guidelines to follow but there needs to be another option for a person in my situation. So I went home and took 6 Benadryl.
