Clonazepam
"This has been a lifesaver for me. Due to a genetic problem that doesn't allow me to metabolize almost all SSRIs, I'm really limited in terms of what I can take to help with my panic disorder. I was on clonazepam about 13 years ago for 6 months. I went to therapy, got better, and weaned off without issue. I just started back on this medicine because of health issues, I've had a relapse of panic disorder. I take 0.25mg once per day, and I am no longer panicking and agitated all day long."
