Hello As you mentioned that your daughter is having severe bouts of cough ( in my opinion caused by sever allergy ). Your doctor prescribed actifed syrup i.e triprolidine+ pseudoephedrine . While asthalin is a potent , safe & effective bronchodilator . First of all I want to make you ,one thing very clear that ASTHALINE inhaler is not a habit forming drug , so you need not to worry at all ( that you have to use it forever) . Now about the question of severe cough . As one thing is clear your daughter is having childhood asthma ( very common ) ,once your daughter will attain the age of 15-16 years , episode of these attacks will subside . When such type of patient visit in my clinic I advise them to take Bambuterol hydrochloride syrup 0.2 to 0.4 mg / kg body weight at the night time . Also give her monteleukast 2.5 mg twice in day ( syrup ) . Hope your daughter will get relief with these drugs . So please get in prescription from a doctor . Good luck.
