My 6 month old son is having cough from two weeks . Docter prescribed alaspam and suventus in first week . No relief was there , he took xray , chest was clear . Then he wrote augmentin duo n brodexyl . Cough reduced but here weather change so he started coughing again n suddenly increased . Noone is having cough in family n no perfume is used near the baby . His saturation was 98 . Now docter has prescribed ambroxyl - S and cetrizin hydrochloride syrup . Chest is clear theoat is also not red . But he is having running nose n severe cough . Plz guide me that docter is doing good treatment or not
