Fever: First aid

Adult

Adults with fevers of 103 F (39.4 C) or higher will most often look and act sick. To treat a fever:

  • Drink plenty of fluids.
  • Dress in light clothing.
  • Use a light blanket if you feel chilled, until the chills end.
  • Take acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin IB, others). Follow the directions on the label. If you have other health problems or take medicine for them, check with your healthcare professional before using fever medicines.
