If your daughter has a severe cold with breathing difficulty, it is important to be cautious with nebulization. Medicines like Budecort help reduce airway inflammation, while Levolin and Duolin help open the airways. The choice between Budecort with Levolin or Budecort with Duolin depends on how severe the breathing problem is and your child’s diagnosis (such as wheezing or bronchospasm), so it should be decided by a doctor. Do not start or change nebulization combinations on your own, especially in children. If your child is having difficulty breathing, fast breathing, chest retractions, or is unable to feed or speak properly, seek medical attention immediately. A paediatrician can assess her condition and recommend the safest and most effective nebulization plan.
