I cannot thank you enough for your feedback about Prednisone and Singulair. Now just four days after we returned from an emergency visit, we are back there and it has turned out that he has pneumonia. I cannot understand why they were not able to figure it out when we went in the first time. Any way I would like to tell you that he was administered proper medicines this time and we were able to really enjoy Christmas without illness and worry. I am to take him again in ten days for his check up and must remember to ask his doctor about the Singulair. Well Merry Christmas to all of you!
