For Asthma "Had the first Fasenra injection two weeks ago to treat 7 months of chronic bronchitis and have been to the ER twice since. Slight fever the first couple of days with a headache. Then the oxygen level began to drop and the heart rate increased. In good health and rarely ill prior to this bronchial infection. First trip to the ER for low oxy. Added prednisone and Levoquin for bronchitis. After three days got bronchoscope and lungs cleaned out. Felt better, came home, but heart rate still pushing 115-120 constant. Three days later back to the ER with irregular heartbeat. Was dropping down in the 40s and too weak to get out of bed. This trip to the ER was dehydrated with potassium and magnesium dangerously low. Dumped Levoquin and switched antibiotics to include antifungal. Home two days later, feeling vastly better except for the rapid heart rate and constant sweating. Lungs and sinuses finally clear. Convinced the rapid heart rate, which is exhausting, was/is the Fasenra. But have no way of knowing. Won’t be taking any more shots of it."

For Asthma "I have severe asthma. By last Christmas, I had 2 shots of Fasenra. The positive is that it made my life better. The negative is I will run a high fever every 3 days in the beginning, and it decreases to every 2 weeks. With this fever, I have horrendous body pain and am wheelchair-bound. I don't like it, but will have to stop it because this is not a life."

For Asthma "Just had my first injection 3 days ago. I'm having a strong fever since then. I can't tell anything more about Fasenra at the moment, but fever is not abnormal."
