This is what happened to me: My pharmacy accidentally gave me Lipitor instead of Celexa. I didn't notice the different pills since they looked similar, I took them at night and of course, I trusted them. One day out of the blue, I started to feel like my skin was crawling, and was disoriented and walking into walls. I was very irritable and had no idea what was going on. I had just finished Rituxan for the first time and was stressed at work, so I thought it was one of those things.
About three weeks after I had the script filled, I was sitting in bed one night and just decided to look up the numbers on the pills. That was when I discovered what had happened. I went to the pharmacy the next day and got the right pills - the pharmacist is a friend of mine and felt so bad about it I couldn't be upset. Within 24 hours, I was back to normal.
Anyway, that was when I realized that I had to get off of them slowly. I started to read other experiences of Celexa tapering and saw that other people had horrible withdrawal also - some the same as me and some different.
I got a script for 10 mg pills and did 20/15 on alternate days for a long time, then went to 15. Then I did 15/10 on alternate days for a long time....you get the idea. I kept doing that until I got to 5 (broke the 10's in half). I even did 5 mg's every other day for a while. Like I said, it took me a long time and I didn't have any problems doing it that way.
I even read that some people who quit cold turkey had permanent side effects such as dizziness. My GP told me I didn't need to taper but he was wrong. Hence, my mistrust of doctors (just one of many stories).
