Hello, Asthma can get triggered due to infections, allergens.Make sure he doesn t get exposed to such substances and take necessary precautions. I can understand your concern regarding your sons current condition. Your doctor had suggested the Montec LC kid tablet depending on his overall condition for the specific duration considering all adverse effects and benefits of the medicine in mind. If the doctor has not suggested that again considering its benefits, adverse effects, efficacy and your child s overall health now, so I advice not to start any medications without consulting your doctor. As the doctor is well aware of your child s condition, he should be consulted before changing any medications. Although you can ask him about the same in your next visit. Till then only give medicines that are prescribed. Also take all the precautions necessary to avoid recurrence of asthma like infections, exposure to allergens etc. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Manisha Auradkar, General & Family Physician
