For Asthma, Maintenance "This is only my first shot. I was very symptomatic the morning of the shot - phlegm, restricted breathing, swelling of appendages, face, neck & throat, redness, burning (had idiopathic anaphylaxis/asthma). Twenty minutes after the shot I suddenly felt an unusual open feeling in my sinuses, and my phlegm was gone. I could take an unrestricted breath for the first time in years. I noticed my sore throat, the burning, much of my swelling, and redness was gone. My eyes were wide and white and I guess weren't swollen because I could focus. I left feeling elated. But driving I began to feel fatigued coupled with bursts of energy, some dizziness and strange mental activity. I didn't feel safe driving and canceled work."

For Asthma, Maintenance "I have just received my 4th Xolair shot. I get them every two weeks. While I do think the shot is making a difference, I am also discovering I am having some common side effects. Apparently, I am getting dehydrated and have some dizziness. Anyone else have side effects, and how long did they last? I was so concerned with the possibility of an anaphylactic reaction I did not catch that I was experiencing common side effects."

For Urticaria "I've had hives off and on since 2002. I am 52 years old, and I've been diagnosed with Hashimoto's and lupus. I was tired of hive breakouts and constantly taking Benadryl, so I decided to start taking Xolair. Within a half hour after the shot, my hands got red and itchy. I told the nurse, she seemed unconcerned. I got very tired, went home, and slept half a day! That night, I got three hives on my leg and arm. The next morning, I was achy all over and got dizzy with a headache. I report I also got some chest heaviness. I called the doctor, and he said it was not from Xolair. I can stop Benadryl, but he wants me to continue shots. So far, I can't stop Benadryl because I'm still itchy! I don't know if I should get the next dose because I don't want worse side effects. Want to eat again."

For Asthma, Maintenance "I have been taking the Xolair shots for 4 months now, and I have really bad leg pain, and my feet hurt, headaches, and dizziness. When I said something to my doctor about it, he said I must have hurt myself, no side effects of the shots. I'm tired all the time. It really has helped me, but I'm tired of the side effects."

For Asthma, Maintenance "I was given Xolair to control my severe asthma and lung damage that came from it. Xolair did solve my asthma issues. It also helped heal my lungs and stop me from getting constant infections. But the side effects of Xolair are real. I did not have any anaphylactic reactions. I did have body aches that felt like my bones were breaking, headaches, restless leg syndrome, bloating, hair loss, dizziness, tremors, and night terrors. My new health care stopped coverage of Xolair, so I stopped getting the shots. It's been 3 months, and I still have extreme body aches and restless legs. I hope it will go away someday."
