An allergic reaction has no long-term effects if the trigger is avoided. Many allergies are mild and pose little threat to the affected person. Some allergies are life threatening and may cause death. Allergic reactions are not contagious and pose no risk to others. Reassure the person to calm him or her down.
Anxiety can increase the severity of the reaction.
The trigger should be identified if possible and removed. If it is an insect stinger, for example, this can often be removed. The stinger should not be squeezed in this situation. This causes the release of more bee venom, which is probably the trigger. If the person develops a rash , calamine lotion and cool compresses can be applied.
