I am 26 years old. My name is amit. I am suffering from cough for last 1 year. My lungs didn't stop to make mucus that causes respiratory problem and coughing. My blood report, Xray, spirometry test are normal. Dr. had given me montelukast and fexofenadine tabs which will help in control but not permanent cure. After taking the tabs montemac fx it works only for few days like 10 -15 days and after that I have to take antibiotics for relief.
