Seretide to Fostair - Any advice?

Been moved from Seretide to Fostair since having trouble with leg cramps/muscle aches related to Seretide doseage. Does anyone have any first hand experience of Fostair? The info leaflet looks a little scary and has worried me!!

I was moved from Seretide to Fostair last summer due to finer particle size, smaller airways etc etc. Prefer it in terms of taste and effect on throat but just been moved back to Seretide due to high doses of Fostair cause hands and feet to cramp and spasm almost permanently!!! Almost ironic that it is the smae thing but the opposite way round! Sorry I have no advice but hope the cramps stop as they were driving me bananas and near to tears at times.

That is odd! Has the Seretide stopped the cramps?

Hopefully the Fostair will work for me then, I'm eating bananas like they're going out of fashion to try and stop the cramps! I'm sick of waking up through the night and catching my legs just before they go into a full cramp ;-(

Pretty much stopped. Mine was this funny kind of cramp along the tops of my feet and hands and was just so painful. Still having spasms in my fingers which is just odd and the odd cramp in my calves but my feet has almost completely gone and that was about 18 hours a day I reckon so so far so good I think.
