Advair HFA and liver damage

I have been on asthma maintenance meds for several years. Prednisone, theodur, pulmicort, singulair, and serevent. I only need steroids when I'm sick and reduced my doses of theodur to none since finding out about potential liver damage. Now I'm strictly on serevent, pulmicort, and singulair. The singulair my allergist explained to me has been said to help with allergy syptoms. He also mentione that Serevent and Pulmicort work well together. He gave me the option of trying Advair but I didn't want to try anything new. My goal is to eventually get off the drugs. Period. My asthma is under controll and more of a nuisance than a life-threatening issue. The meds are for preventative purposes. I have very few attacks in one year. I have never been fond of taking maintenance medications and have been more concious of side-effects after the whole Vioxx thing. I found this posting board by total accident and boy am I glad I did. Serevent is an ingredient in Advair. I have had terrible muscle tightness in my back and also experience abnormal weight gain without any change to my diet or exercise habits. I have been on serevent for several years (since it's product launch) and became more religious about using it over the past year. I am probably about 30lbs overweight and could not figure out why until now. Thank you for letting me see this. This morning was the last time I am taking serevent. It's not worth it!!!
