My husband was doing some cleaning with bleach in the bathroom yesterday.  He has developed a very bad cough and was coughing through most of the night.  He has asthma and usually takes spiriva and ventilin hand halers.  He is not getting any better. This morning he woke up with lots of coughing.  Should I take him to the hospital to have him checked?
Hellos you mentioned that your husband is an asthmatic patient and taking treatment for it. He developed sever allergy due to gases of bleach (chlorine & ammonia 0. Due to allergy to these ingredients he develops bronchoconstriction and this causes sever bouts of cough. Now in my opinion you should at once go the hospital for urgent care. Good luck.
