Severe Allergic Reaction (Anaphylactic Shock) (cont.)
IN THIS ARTICLE
Follow-up for Severe Allergic Reaction
You will usually be observed for at least six hours after the beginning of the reaction. Occasionally, a reaction will seem to get better and then recur, and even worsen, in a few hours. Sometimes the severity of the reaction will require admission to the hospital.
Upon leaving the hospital emergency department, you should immediately obtain the medication prescribed for you. You should carry these at all times to prevent another reaction or lessen its severity.
Is It Possible to Prevent a Severe Allergic Reaction?
Strictly avoid contact with the substance (allergen) that was the trigger.
People who are likely to be re-exposed to (or are unable to avoid) an allergen that has caused them a severe anaphylactic reaction in the past should see an allergist for desensitization. Skin testing may be required to help identify the allergen.
