"first- there is absolutely no difference between brand and generic. there can&#039;t be legally. it is the same active ingredient and the same strength. it&#039;s just the name and cost and inactive ingredinets. 
 this being said... i don&#039;t understand where negative remarks come from. this medicine is amazing. i took it a while ago then asked to be changed to something else. i gained 20lbs and the other med didn&#039;t so anything. so i asked to be changed back. my leg muscles hurt and i have a few word issues but it&#039;s an amazing medicine."
