Why does my mother?s severe dry cough get worse when she lies down and improve when she sits up, how long will it take for her prescribed medicines, Histafree and Ventidox M, to relieve her cough, and how can she find relief?
It is very common for a dry cough to worsen when lying down because gravity allows fluids to pool at the back of the throat, triggering the cough reflex. Sitting up helps ease this. Her prescribed medications, Histafree (fexofenadine) and Ventidox M (doxofylline and montelukast), will help. Histafree typically works within a few hours, while Ventidox M may take 2 to 3 days to fully soothe her airways. To help her rest, try propping her head up with extra pillows, encouraging warm fluids, and using a humidifier.
