Hiya, my son has been on a 16 week trial for Xolair. He is now on week 14 and feels it has not done anything for him. When we started it my main concern was he was starting at the beginning of the summer which is typically the best time of year for him and was worried he would have a false result. As it turned out it became the worst summer we have had (not blaming Xolair for this!) and he has needed Pred continuosly for the past 9 weeks and is having problems coming off it. He normally has regular courses of Pred but manages a break in between.
Does anyone know at what point during the trial you should notice a difference. He is understandably pretty fed up with having the injections and is now worried about having a 5th if it is not helping. It would be lovely to hear some success stories, especially if it helped toward the end of the trial.
