Since being on fostair 200/6 i have put on a considerable weight gain. Has anybody else had this reaction or is it just coincidence. It is working well for me but i dont like the weight gain and am considering going back on sybmbicort 200. I i didnt have this problem on it but was also not taking it regularly and my peak flow reflected this. Since being on Fostair 200/6 my peak flow has risen and my asthma improved but i do not like the weight gain. Please help.
