What can I do for my 3-year-old child who is coughing and has a fever?

It is recommended to try treating your child's fever with either Tylenol or Advil, but not both at the same time unless advised by a medical professional. In addition to medication, nasal hygiene with saline solution like Hydrasense or Sinus Rinse can help prevent mucus from dripping down the throat and causing coughing. If the fever persists for more than 72 hours, it is important to seek medical attention promptly.
