while there are no drug interactions between steroid nasal sprays and the ingredients in tylenol plus cough and runny nose you should only give your 4-year-old that type of combination product if you have been directed to do so by her pediatrician. generally as a pharmacist i do not recommend combination cough and cold products especially in children. they often cause confusion and contain ingredients that the child may not need at the time. you should always check with your pharmacist before giving your child an over-the-counter medication to treat their cough or cold.
my 4-year-old daughter is taking a steroid nasal spray. is it ok to give her children's tylenol plus cough & runny nose?
