How do you treat a ear infection?

Depends: There are many types of ear infection requiring different strategies. The main symptom is pain and therefore painkillers are usually given. Tylenol (acetaminophen) or Advil are the usual ones used. If it is an external ear infection ( of the ear canal) then usually antibiotic ear drops in addition suffices. In middle ear infections oral antibiotics may be required. Best judge is the examining physician.
