i have been on advair 250/50 for a year. i have gained 50 lbs and if i miss a dose its apparent as i wheeze and suffer. i want off this medication the dr insists the advair isnt causing my weight gain but after alot of research i know diff, and i didnt change my eating habits. anyone suggest another medication i can ask dr to substitute? i take singular and have proventil but need something more. advair isnt it i dont think.
