I am new to asthma drugs, diagnosed with asthma in November at 44 years old. I hope that this helps someone else. I was put on Advair a few weeks ago. Along with Zithromax antibiotic to clear up the URI. Also was given Albuterol was severe breathing problems. The Albuterol helped of course (no sleeping though) and the antiobioitc as well as Advair seemed to get the problem under control in about a week. A few days after the anitibiotic was done, symptoms returned, but not as bad. Dr. put me on prednisone (the sterioid), and Advair. That was a hard week, but as before the symptoms improved. however, a few days after the prednisone course symptoms returned. The Dr. then decided to continue with the Advair, another longer course of prednisone and added Singulair to the mix. Within 3 days of taking the Singulair with the Advair, I could not sleep, had severe heart palpitations, wheezing, and the heartburn was so bad I felt like I had a huge stone in my chest and throat and several moderate asthmas incidents where I had to use the Albuterol. I had a headache, dizziness, and could not sleep. The Singulair MADE MY BREATHING PROBLEMS WORSE. And if you read the side effects of Singulair they actually can make worse the very asthma symptoms they are supposed to improve. It was a real eye opener. READ YOUR PATIENT INSERT FROM THE PACKAGE. I felt like I was going to die and each day felt worse. I discontinued the Singular after 4 days and within 24 hours felt much better and in 48 hourss had none of these syjmptoms. My doctor was just incredulous that this MIRACLE drug THAT MOST PEOPLE NEVER, EVER HAVE problems with could bother me. Drs try but you know your body better than anyone else, dont' be shy and stand your ground, they are wrong sometimes!!So listen to your head and heart, and body and read the labels. I had to figure this out for myself. On to the next part of the story, I am on Advair now for about 8 weeks, and notice in the past week, I am light headed, dizzy sometimes, am not sleeping a sound sleep, waking every hour or so, am NERVOUS AND JUMPY, my legs and arms are so weak, I can barely walk, so so tired, I feel like I am just slipping away. It is hard to type this because my fingers are so shakey and weak. Thank goodness I found this web site. I am discontinuing the Advair, I know in my gut that after reading this and listening to that little voice in my head that I am sensitve to a lot of drugs anjd Advair is on of them. It might be 1-3% of the people tested that have these awful side effects, but it doewsn't seem such a small group if you are one of them. And if you look at the studies, they only test around 400 people!!! So my journey continues. I am not totally convinced I even have asthma..............Please email if you would like.
