Hello Cynthia! Thank you for using the #asksudrexfeature. Fever may occur in anyone at any age, it is a higher-than-normal body temperature ( > 37.5 C) and it usually occurs in response to an infection be it viral or bacterial. Injuries, drugs and heat exposure are some of the things that can cause a fever too. Seek medical intervention if your fever lasts more than 3 days, or gets worse. If you have difficulty breathing or seem confused see a doctor. In general, mild fever can be reduced with medications like Ibuprofen, Acetaminophen or Sudrex Headache & Fever. Taking a warm bath or applying warm towels to your skin may also help to reduce your feverish condition.
