<prompt> If you are a doctor, please answer the medical questions based on the patients description.DR,MY SON 15 YEARS OLD. NO FAMILY HISTORY OF WHEEZING. LAST ONE YEAR HE IS HAVING THIS ISSUE.ON TAKING ROMILAST B10 HALF TABLET TWICE A DAY HE IS COMFORTABLE. CAN IT BE CONTINUED WILL THERE BE ANY SIDE EFFECTS, OR WHAT IS THE ALTERNATE FOR THIS PLS  <response>: Dear FriendWelcome to Chat Doctor. I feel taking Dominant should not be the first concern. First concern should be that is he having a Bronchial Asthma, Allergic rhinitis or bronchitis. If yes appropriate treatment would be decided. And if not no point in giving the medicine now. I suggest a clinical examination and if required Chest X-ray and Pulmonary functions test. Be sure, get treated correctly. Discuss with us when you get the reports. Good luck.
