Hi,
Basically, it is a diagnosed case of
asthma on regular inhalers, now having significant
cough at night. Here the possibilities are:
1. Poor control of asthma- needing up-gradation of treatment
2.
GERD (backward reflex of stomach contents back into food pipe / esophagus- need acid suppression and diet modification
3. Depending on prevalence in your area, this may be an unrelated infection like
pertussis / mycoplasma- easily treatable with antibiotics
If I were your treating doctor, I will ask you to video record an episode to see whether its pertussis, and after examining the chest will decide further course of action. Your doctor will guide you. Meanwhile, ensure all asthma measures like avoidance of dust in room, proper technique of inhaler use and make sure the canister is nit empty.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Muhammed Aslam TK, Pediatrician
