I was on Advair then my doctor switched me to Serevent and Qvar and now I am back on Advair. I have gained 150lbs since starting this medication in 2002 and just now realize that maybe my weight gain is due to this medication. I also started having short term memory problems as well as swollen legs and anxiety. I never had these problems before. My doctor then prescribed me Xanax for Anxiety but it made me too tired so he prescribed Zoloft which boosted my short term memory and then prozac which I have recently just stopped taking. I never knew that all these prescriptions could be the cause of my health decline. I am only 38 and use to be in top shape playing tennis but now I don't have the energy to do much at all.
