The only cure for anxiety is, ultimately deconditioning.Meds definitely can help smoothen that process , but that needs to be addressed carefully, as PRN /SOS will reinforce the maladaptive conditioning. Ultimately the simplest analogy is to not respond to the false fire alarm - and the brain eventually stops treating it as emergency. Easier said than done , but that’s the hard facts. Most suffer from Somatic symptoms, but keep the noise peripheral, never central- by returning to whatever you are doing, however badly. As for anxiolytics- Fixed time dosing for a finite period prevents maladaptive conditioning and makes exposure therapeutic. Ultimately, for a panic attack emergency- creating a threshold rule is better, and even then hydroxyzine like antihistamines serve better than to messing with Benzos.
