From this study (4 years ago):
Developed sudden onset severe asthma while feeding a bird on my shoulder, in the zoo's bird aviary, 2 ½ years ago. Never had breathing problems in my life, but couldn’t breath after hour long choking spell I suffered when the bird flew away. From that night until my lung collapsed two months later, I was prescribed albuterol, duoneb, and prednisone (with constantly increasing doses because "asthma" was non-responsive). After treatment for middle right lobe collapse (mucus plug removal) I remained symptom free for a 18 months, using only Singular and allergy meds. I was diagnosed with prednisone allergy 3 days after leaving the hospital for the lung collapse, so I did not take anymore. When symptoms returned, a year and a half later, which has been a year ago now, they included rales, coughing up blood, and chronic pneumonia (hospitalized 10 times this past year). After 6 months, my digestive system became involved, and I developed tachycardia and heart pain/spasms. Been to 3 pulmonologists who diagnosed me with COPD and asthma, swallowing problems associated with recently discovered hiatal hernia causing choking/aspiration pneumonia, and aspiration of stomach acids. I was taken off the singular because it was believed to cause "shattered glass" appearance on xrays. Latest (4th) pulmonologist did broncoscopy with biopsy discovering eosinophilic pneumonia, but no COPD or aspiration. Over past year, I have been given i.v. steroids and benedryl in hospitals, and have followed with weekly steroid shots and taking benedryl at home, due to allergy to ingredient in the tablets. Yet, am still ending up in hospital every month, because shots not strong enough to keep me free from pneumonia, although extreme doses of prednisone 2 ½ years ago didn’t keep lung from collapsing either.

Female 45 y/o, NYC: after 5 years of severe asthma and a collapsed lung I finally determined I was severely allergic to my thyroid meds. Possibly to povidone an ingredient in the brand name thyroid medication Sinthroid. This ingredient is not in the generic brand and I seem to be ok now on the generic. So you see I NEVER HAD ASTHMA, I was having a severe allergic reaction. Since I have Hashimoto's Thyroiditus I may have issues with iodine. So you should check if u started any new meds around the time your breathing problems began. I also had a severe psychiatric response to medrol dose pack (methylprednisolone)and ended up in the psych ward. if you have a thyroid problem too much T3 or cytomel can also cause breathing problems as well. Last, weak adrenals will cause lung problems, check out the book "Adrenal fatigue-The 21st Century Stress Syndrome" by James Wilson

PS the birds may just have been a coincidence. Once I bought a new pair of shoes and one of my feet began to hurt pretty badly and I began limping. I thought it was the shoes and it took 6 months to figure out that the foot pain was caused by an abnormal thyroid TSH level of 23 (normal being around 2). It was just a fluke that I bought new shoes when my foot began to hurt. Then I switched from the generic thyroid meds to the name brand Synthroid and a month later my asthma nightmare began. Recently I was taking Seroquel for a period of time and I noticed my nightime asthma returned so i went off it. I checked the ingredients later and discovered Seroquel also contains Povidone!
Andrea on Nov, 20, 2012:
and one more thing, i read that asthma used to be treated with thyroid medication so if you have not been tested for thyroid disease perhaps you should be. and please note that the normal TSH levels should be between .5 and 3.0, this is the new range and can be verified by the appropriate Endocrinology Associations. to find the article about thyroid and asthma: search for Dr. Derry, thyroid and asthma.
I had Juvenile Rheumatoid Arthritis as a child, in addition to various other autoimmune problems, including but not limited to Epstein Barr Syndrome, Chronic Fatigue Syndrome and Seasonal Affective Disorder. I also suffer from chronic depression which is exacerbated by situational traumatic events.
I just want to know if I take both of these will anything bad happen?
Can you answer these questions (what is this?):
- By vic: Can a cough develop after 5+ years of using the drug?
My hypertension is under control but I have developed a persistant cough. It is possible for Amlodipine Besylate being the cause of my cough after 5+ years of use?
- By creolesherbet: Does claritin have an anticoagulant effect?
I thought I had conquered my nosebleed problems with saline nasal mist and saline nasal gel, but now I've started on Claritin (actually Walitin, Walgreen's knockoff) for an unrelated reason and the nosebleeds have started again. Is this because of the Claritin or just a coincidence?
