Hi, can anyone offer any advice. Dad's had ipf for nearly 6 years now but has dramatically gone down hill over the last few weeks. He is sleeping more, lost his appetite and now needs his oxygen 24-7. We can cope with most things but this awful cough is the most dabilatating and upsetting thing for us all. Despite breathing exercises he coughs that much he's unable to breathe and passes out, he was fairly independent til now. He's on morphine and codeine linctus. He's was admitted to hospital overnight but other than linctus and excluding infection they have done nothing. Any suggestions on how to manage cough? Is this normal par of the course?
