I started atrovent HFA 17 MC inhaler perscribed by my internist but it made me so nauseous I had to stop (with his approval). I am wondering how long does it take for the nausea to go away after stopping the atrovent? It has been 2.5 days that I have stopped and am still extrememly nauseous. I have been through chemotherapy in the past and have used an old perscription for zophran (8mg), although this has been no help either. Does anyone know how long this will go on ?
