My father is 76 yr old recently he was having problem in breathing and cough problem is also dominated on breathing a noise which is coming out shows that the lungs are effected.doctor suggested CLAVAM 625 and a syrup GRilinctus-BM two time in  a day.sugeest some other or additional medicines as he is not feeling well till now.
Antibiotic and a cough remedy should do good, In case it does not help and gets worse it's time to go to the hospital rather than trying home remedies. Noisy breathing, He might need a bronchodilator at the hospital
