I've been on Prozac for a good number of years...switched from Paxil, that was making me gain tremondous amount of weight which did not help with my depression. Prozac though has worked wonders 4 me and made me funtionable again...has seemed to make me very tired, lagey and at a stand still, plus gaining weight again. Doc has prescribed Wellbutrin...thinks this will be better for my depression, will give me more energy, & should help with weight. My one concern...i've researched all the side effects and very concerned about, though rare, a serious one which is seizure. I have not seen this as a side effect for any of the other depression drugs. Why? Is it a very rare occurrance? Did question doc about my concern..he indicated due to all my symptoms and complaints this is the drug he feels is best...and did indicate that the rare risk of seizure comes with all of the usage of these meds?? I do understand there are side effects on any med you take...but this one has me very worried. I cannot take a drug that is suppose to help me and constantly be thinking that i'm going to have a seizure...this defeats my purpose of using it, plus the worry increases my anxiety level so much as i've had a panic attack...Plz anyone with some logical answeres...i'm driving myself crazy. Let me reiterate..Doc feels safe for me to take. Also once on the Wellbutrin for period of time .. does that side effect "seizure" subside???
