I am a victim of asthma and was told to have Xopenex three times a day. But currently, I am suffering from a chronic sinus infection, cough and sore throat which have become worse by my severe coughing. I would like to know whether I can hike up my dosage of Xopenex to tide over these rough days till I get better. Any solution to my problem would be deeply appreciated. So please do get in touch with me at the earliest and help me out of my problem.
