Allergic Reaction (cont.)

Follow-up

Allergic reactions are sometimes unpredictable.

  • Always watch for a return of symptoms as medications wear off or exposure to an allergen trigger continues.
  • Return of symptoms may be sudden and severe.
  • Anticipate a possible return of the reaction and a need to return to the medical office or emergency department.

Use all medications only as instructed or as prescribed.

  • Therapy to suppress an allergic reaction may involve long-acting antihistamines and other anti-allergy medications in combination to suppress the body's immune response.


  • Severe cases may require a course of steroid treatment lasting as long as four weeks.
