Venlafaxine
"I have been on this medication for over 15 years. I can tell you that this is the absolute best medication for panic attacks, the problem is that I never had any panic attacks until I quit taking the pill after a year of use. I was prescribed this when I was 18 after being hospitalized as the result of several traumatic events. I started on 32 mg and eventually was bumped up to 150mg and then 225 mg. I weened off and survived the withdrawals and felt amazing seriously felt like the best moment of my life but about a year after I stopped taking it, the depression came back twice as bad. "
