I have been on citalopram 10mg for 4 years because I had a panic attack one day at work. The medication helped a lot, for a long time. However, I'm starting to have really awful anxiety again. A lot has gone on in the last year (death of my father, switching schools, breakup of relationships). Anyways the anxiety has gotten so overwhelming that I don't even want to go to class, or go anywhere for that matter. I tried upping my dose to 20mg of citalopram, which I've been taking for 3 weeks. The side effects are awful. Made my anxiety 50x worse, made my thinking weird and scary, mood swings, panic attacks everyday, lightheaded, dizziness, feeling like I'm going to pass out every time I'm in public. I guess I'm wondering if anyone else has had these side effects before when upping a dose. It's been such a nightmare, I don't even want to take the 20mg today. has anyone ever had these side effects and then came out on the other side? Any help would be appreciated. Thank you.
