HI DR. Grief, my name is Roberta. At the end of February I had the flu. After the flu started to go away I developed a chronic cough accompanied with mucus. I went to my a physician`s assistant who prescribed Benzonatate 200 MG take 1capsule by mouth every 8 hrs. as needed. I did this for a few weeks and this did not help. My cough was atill persist and accompanied with mucus. I coughed so hard and could not breath when trying to clear the mucus from my throat. I have gone back to my Dr.s office after a month and was seen by a nurse practitioner who prescribed Ventolin HFA 90 MCG inhaler, 2 puffs by mouth every 6 hrs as needed, and Montelukast SOD 10 MG, 1 tablet at bedtime. I was told that this won`t take affect right away, that I have to take this over a period of time before it does! Does this sound right to you?

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you are not taking right treatment. By your history and description, possibility of post infectious bronchitis is more. This condition is common after common cold due to flu infection. And treatment of choice is inhaled corticosteroid (ICS). Ventolin is short-acting beta 2 agonists (SAGA). Its action lasts for 1-2 hours. So frequent dosing is required. Montelukast is anti-allergic, and it has no role in post infectious bronchitis. So better to consult pulmonologist and get done PFT (Pulmonary Function Test). PFT will tell you about severity of the disease and treatment of bronchitis is based on severity only. Better to stop montelukast and start ICS after discussing with pulmonologist. Hope I have solved your query. Wish you good health. Thanks.
