If a young child has a cough and runny nose, parents can deal with it in the following ways: 1. Give the child antihistamines, which can effectively reduce the child’s runny nose, such as loratadine and cetirizine syrup, which are second-generation antihistamines that not only improve the child’s runny nose, but also do not cause the child to have the adverse reaction of drowsiness. 2. Perform nebulized inhalation therapy. The main drugs commonly used for nebulizer inhalation therapy include budesonide suspension, Bolicam and Echolac, etc. The combination of these three drugs has a significant alleviating and therapeutic effect on the child’s cough. 3. Blood tests. If the white blood cells in the routine blood test are high, the cough and runny nose are mainly caused by bacterial infection.
