"i began this medicine a year ago and have been stable at one dosage, 40 mg, for 7 months. i have experienced a large weight gain of 20 lbs on my small frame and have become very unhappy. i trusted my physician when i chose this medication. he told me it is one of the only ssri&#039;s that does not cause weight gain. i feel all the positive side effects i first experienced have faded. i am going to be going off the medication this week with hopes of losing the weight. gaining so much weight for a young girl is counterproductive when considering what the medication is originally prescribed for. i am a 23 yr old female."
