Most allergic reactions respond well to medications.

  • Hives, swelling, breathing difficulties, even anaphylaxis often improve and disappear in minutes to hours.


  • Some rashes take several days to heal.


  • Your health-care provider may want to monitor you for a few hours.


  • A dangerous allergic reaction may warrant an overnight stay in the hospital.

Allergic reactions will continue with continued exposure to the allergen or trigger.

  • You need to avoid any triggers you know cause an allergic reaction.

  • Continued medical therapy is necessary for continued exposure.

You may be referred to an allergy specialist if you continue having reactions.
