I recently began to take Advair (about 2 months) and have experienced very few side effects. My voice gets a little heavy by the end of the day and I sometimes wake up with a sore throat (once a week). But my doctor had warned me about these effects and so I was not surprised. I do have more phlegm, which I hadn't associated with Advair, but rather with allergies. Overall, I am very pleased with Advair. I had a chronic cough for almost 3 years and used Albuterol inhaler 2-3x a day before begin prescribed Advair. I have not used the inhaler once in 2 months. I will continue to use Advair as prescribed, 2x a day!
