While taking Chuan'er Ning, the child's breathing became difficult again. Can Boli Kangni be added?

Patient's question:

Onset time: 2 days ago
Laboratory test results: Previous treatment history and effectiveness: The child has allergic asthma and is currently taking Singulair. The past two days, he has experienced some wheezing, so I gave him Cartrol, and yesterday I added Chenodiol. He has taken it three times, but he is still wheezing today. Can Bricanyl be added?
What kind of assistance is needed: Guide on how to use the medication. If Bricanyl cannot be added, what should be taken instead.

Doctor's answer:

Your child is only 4 years old and suffers from allergic asthma. Using Xolair (the proprietary name is Montelukast Sodium Chewable Tablets) is appropriate because this medication is suitable for the prevention and long-term treatment of asthma in adults and children over 2 years old. It includes preventing daytime and nighttime asthma symptoms, treating aspirin-sensitive asthma, and preventing exercise-induced bronchospasm. It is recommended to use only one medication! You cannot provide Bricanyl today. See which medication works best for your child and use the one that is most effective. Stop using other medications.
