I'm really worried about my son. He caught a cold back in January 2014 and then started coughing a lot, having trouble breathing too. A doctor prescribed budate 200 rotacap, which he used for two years. After that, everything seemed fine for about eight months, but then the symptoms returned in December. So we saw another doctor who gave him a Levolin inhaler. We've now consulted a pulmonologist who has prescribed formonide 100, deriphyllin od 300, and montair lc kid. How long do you think he should keep taking these medicines?
