How to Stop a Histamine Response

A histamine response is your body's reaction to an allergy such as pollen or food. It is an overreaction to foreign particles that causes your body to dilate blood vessels. This can create excess mucus, swollen sinuses, a closed up throat, rashes and other conditions. Some of these histamine responses are not dangerous and will stop within a short time, but others can be life threatening. It is always best to try to stop the histamine response to improve body function.

      Remove the offending item or remove yourself. If you know what is causing the histamine reaction, have someone remove it or leave the area. For example, if you are visiting a home and animals cause an allergic reaction, leave the house to get some fresh air and stop the reaction. If flowers from your daughter cause a reaction, politely say thank you and put them in some part of the house that you don't go. This doesn't work in spring when everything is in bloom, but for concentrated incidents, it will stop the reaction.

      Wear a mask to prevent or stop a reaction. If the allergy remains in the air constantly for a week or so, wear a mask that filters the air, similar to what a doctor wears. It covers the mouth and nose, and prevents you from breathing in any more of the particles that create the histamine response. People allergic to grass often wear masks when they have to mow the law to prevent allergic reactions.

      Take medication. Many individuals ingest some type of medication to stop or reduce histamine response to an allergy. Antihistamines are the wonder drugs for common allergies such as flowers and tree pollen, grass or animal dander. Medical professionals and individuals utilize epinephrine autoinjectors (trade names include EpiPen and Anapen) for severe allergic reactions to things like bee stings or food allergies. These medications work well to stop the reactions and get you feeling normal again.
