I am a 42 yro who has been using Advair 250/50 for over a year now. The Doc prescribed 2 puffs a day but I prefer to take 1 puff every day (shhhh...don't tell the doc!). Before going to Advair I was taking albuterol inhaler on an as needed basis (allergy/exercise induced asthma). I am not sure if its old age, or me moving from NE to the SE USA (where its hot & humid), or Advair itself but I am noticing that I am getting more and more dependent on Advair to the point where If I don't take my once-a-day-puff, I find myself starting to wheeze. I was never like this with Albuterol. Sometimes I wonder if there is a chemical in Advair that makes you become dependent on it just so the drug company can make more profit on your depenency. The other two minor side effects that I attribute to Advair is the occasional hoarsness in my voice, and a minor tingling sensation in my arm and leg (Restless Leg Syndrome?) at night. Anyone else can make a connection between Advair and RLS? I don't smoke, drink caffine free drinks, athletic, and work out regularly, and take no other medications or vitamins.
