I have been on Topomax for 2 years now at 200 mg. for mood stabilization. I was recently hospitalized for my depression and they upped my Topomax dose to 400mg saying it was the "therapeutic dosage". I went into the hospital weighing 116 pounds and I am 5' 6" tall. I started having diarrhea within a couple days. By the tiime I left 2 weeks later I had gone from a size 4 to a size 2. A month and 1/2 later I had lost 15 pounds, had severe abdominal pain everytime I ate, diarrhea every morning, nausea, and had absolutely no appetite. My psychiatrist insisted it was not the medication and I went to a gastroenterologist for the full workup- ultrosound, colonoscopy, endoscopy and surprise surprise they found nothing. My Gastro doctor concluded it must be the meds so I started backing down on the Topomax and already the diarrhea has stopped. I am at 250 and up to 101 pounds now. I am taking in over 1200 calories a day but I still can't seem to gain weight. My doctor still doesn't believe it's the Topomax but it all points in that direction. Instead they insist I'm just not eating enough But I make sure to force myself to get down 3 meals plus 2 ensures and some snacks. I still am waiting to get some appetite back. I know some women would love to be in my place to have to try to gain weight but I feel like I'm dying all the time. I have no energy, I can't even get up in the morning to take care of my kids. My fiance left me because he got so fed up with my "sickness" and thought it was all in my head. I have my mother living with me now just to help me take care of my own children and it breaks my heart that I don't have the enery to play with them. I can't see my psychiatrist for 2 more weeks so I am taking my level of medication into my own hands which I know you are not supposed to do but at this point it's that or lie in bed feeling like I'm just wasting away.
