She started taking Kalydeco on thursday. And so far we haven't noticed anything other than she is running 100 fever, which could be normal for her since she was starting to run a slight fever before we started. She has no cough, no sinus drainage, no nothing. I keep asking her if anything feels different and she says no but she is 7 and the child NEVER complains so I don't know. I can tell you that I have a Piko Meter and her PFT's were the highest they have ever been on the 15th (1.41) and when she started running a slight fever the highest she blew was a 1.35 the whole last week until Saturday. On Saturday she blew a 1.44!!! So I have no clue whether it is working or not. Good thoughts!! <img src="i/expressions/face-icon-small-smile.gif" border="0">
