My son has been on Asthalin rotohaler and Budecort 200 rotohalers for 6 years. He takes one rototab asthalin twice a day a day as well as 3 tabs Budecort a day. He has 10mg tab of antihistamine and and has just come off of a 14 day course of Montelucast. He is still coughing and doc says he needs another course of oral steroids to bring it under control (prednisone), the second time he has had to take this in the last six months. I am worried about the side effects of all this! Does anyone have any info on this? We live in Kathmandu which is very polluted (exhaust fumes). We are thinking of returning to the UK as last time we were there the symptoms we went away.
