What causes persistent cough?
Patient: my son who is 25 had been having a persistent cough since he left his trip to the Philippines 3 weeks ago it was actually beginning to hurt me when he cough, but he said only his throat hurt a little from coughing so much. I decided to offer him the Bromphenir-pseudoephed DM the Doctor had prescribed for my granddaughter in July this year even though she is 12 Years old it seem to work great but now we are out and we need to know what over-the=counter is similar Thanks Doctor: Respected user , HiWarm welcome to Healthcaremagic.comI have evaluated your query thoroughly .*  The probable reason is allergic  bronchitis .*  Suggestions for better recovery-  Gargles with salted lukewarm  water  added  peppermint  oil  3  times      a  day .-  OTC  molecules  as  tessalon pearls  and  mucinix  od  can help .-  Avoid exposure to pollen , dust particles .-  Refrain from smoking , alcohol .Hope this will help you for sure .Welcome for any further guidance .Regards dear take care .
