I recently just realized the reason for my 40 lb weight gain in only a year. LEXAPRO!! That evil evil drug. But the thing is, I have been so happy while taking it. I went to the doc this week and when I stepped on the scale I almost had an anxiety attack right then and there. I dont weight myself regularly but I knew I had gained ALOT of weight but geeze I weight 182.2. WTF???? When my doc asked me if I thought the weight gained correlated with when I started the lex, I thought and said no. Theres no way because I have always been told that Lexapro did NOT cause weight gain. Anywho, I am 5'10 and usually weight around 150. Well then I began to think on the ride home about the last year and a half. Hmmmmm I was so perplexed for so long, now it all makes sense. Heres my story. Around Jan of 2007 after being on Wellbuturin for some time, a Dr switched me to Lexapro 10 mg because I felt like I was starting to feel depressed again. At that time I was around 150 lbs. So I began taking the Lexapro and within a few weeks I could tell that all of my pants were tight. It never crossed my mind that I was gaining weight from that stuff. I havent always been as in tune with my body as I am. Well over the summer of that year I moved to Virginia and really felt happy and secure so I just stopped taking the Lex cold turkey with absolutely no side effects. Over the next 2 months I started loosing weight effortlessly with absolutely no exercise. Got down to a size 6 (140 lbs) and Ive never ever been that little. I was eating out a lot and drinking a lot of beer too. Weird I know. Well I maintained my new skinniness for 6 months. During that time I went through a very bad break up that made me go crazy. I refilled my Rx for Lexapro 10 mg and It helped me through that time. No weight gain. Then I got my Rx increased to 20 mg and within a month and half or so I went from a thin and cute size 6 to not even able to button and 11. Still I did not correlate the weight gain with the medicine. Since then I have been so down about my weight. Ive dieted, exercised but cannot stop the weight gain. After this weeks doctors visit, I started to research this idea and my goodness at what Ive discovered. I can not believe how many people out there are going through this mess. I have become a hermit and never wear anything but scrubs. All those cute clothes just collecting dust in my closet. I refuse to buy bigger clothes. I tried on a 12 at Old Navy and left feeling like I was gonna be sick because I could not get them over my hips. This is insane. I cant take it anymore. I havent taken any Lexapro since Wednesday. I never want to take that stuff again. Now I am scared to death that my metabolism is screwed up forever. When will the weight start to leave?
