My mother (86 years) is suffering from pulmonary fibrosis and had recently been diagnosed with pulmonary tuberculosis. She had been on TB drugs for a week now. My mother has been on 'Singulair' for more than two years and 'fluimucil'. She had no asthma. She dislikes taking the 'fluimucil' as she complained that it is sourish and spicy. My mother is bedridden and she is very exhausted even from eating (soft diet - little but frequent) to turning her while changing her diapers. My mother only takes short naps at night and rarely sleeps. She also has a lot of worries and we could not talk to her because she has hearing problems. My concern is that she is having difficulty breathing. It starts off with her feeling hot and then cold. The breathing attacks are sudden and typically occur anytime from midnight to early in the morning which last for more than 30 minutes. She had been given oxygen from the oxygen concentrator (small portable machine) but this does not ease her breathing during severe attacks. She requested us to fan her manually as she complained that she could not breathe (non circulating air). My sister and I had noticed that the attacks occur after 8 hours of taking the TB drugs. The doctor did not at all concern himself with my mother's fibrosis. He focused his entire attention only on her TB. He also mentioned that the hospital staff could not do anything with my mother if we were to send her to the emergency room during attacks. He added that her time is due. This is a very disappointing thing to hear. I sincerely hope that anyone would take the time to provide some suggestions for the following questions. Any suggestion regarding care providing is also welcomed. I would like some suggestions on how to relieve her breathing difficulties. I would also like to know whether the TB drugs could had aggravated her breathing? Could there be a possible side effect from the TB drug interaction with 'fluimucil' and 'singulair'? All suggestions are welcomed. Thank you for your responses and time.
