Worry to hear about your Panic Attack. It could very likely be related to the medication change. It takes awhile to adjust. Talk to your doctor about your experience.
I recently had what for me is considered a "Bad" panic attack. I haven't experienced an attack of this magnitude in the last 2 months or so. It lasted about an hour and kept coming in waves ... shakiness, flushing, chills, fear of heart attack, etc. I'm attributing it to the fact that I recently changed medications from Lexapro to Vilazodone HCI. I'm curious if anyone else has experienced a set back to medication changes? Does anyone have knowledge about Vilazodone? I thought I was doing much better until this happened. The attack left me physically drained and worried that I may have another attack. Any info would be helpful
