Hi. You can probably find better links by searching on this site. I had this one bookmarked and it includes some common symptoms. Personally, all I had was the fever on my initial high dose. I get it weekly, though, so your doses may be higher and more prone to side effects. Or perhaps you were just coming down with the flu? Hopefully, you won't have any problems with later doses.
