I was recently prescribed 20mg once a day of Citalopram for anxiety. My doctor warned me that I may feel "a little nauseous" for the first week but I never expected to have the horrible reaction that I did. About an hour and a half after taking my first and only dose I got so hot, I was sweating, my entire body ways shaking, I was so nauseous I thought for sure I would throw up or possibly pass out, I couldn't keep my eyes open. I even hit my head hard off one of my kitchen cabinets by accident because I was so out of it. After about four hours of this some of the symptoms subsided a little but some did not and I still felt so horrible. I took the pill at 9am. At 4am the next morning I was awake puking my guts out. It is now 4 days later and I haven't taken another pill since but I still feel messed up! This morning when I woke up I had extreme anxiety, worse than ever and I couldn't even pinpoint anything in particular that I was anxious about. My hands were shaking, I felt light headed and nauseous and overall just...off. I understand that my reaction was probably worse than most people. Everyone reacts to different medications in different ways and me and Citalopram just don't mix. I also know that if I kept taking it these symptoms would eventually subside as my body got used to it but for me the side effects, even if they are temporary just weren't worth it. I woke a full-time and there is no way I could work in that condition, I had an extremely hard time just making it through the last few days. My question is, has anyone else experienced these symptoms after only one dose of Citalopram and how long did it last? Is it normal that I still feel like this after 4 days? Could I be going through withdrawal after only one dose? Thank you for your help!
