Recently I had to double up on my normal dose of fostair, due to a really bad cold and a chest infection. The doctor gave me some antibiotics and I kept on taking my increased meds for about 4 weeks till my peak flow got back to its normal ready and remained steady. There's only one side effect I have noticed, my near vision has deterioted over a week or 2 and I read on the Web because I have being taking the maximum doses for 4 weeks and extra ventolin it can cause eye problems.
Has anyone else being effected like this
