A few people are very allergic to things such as insect stings, drugs or foods like peanuts or shellfish. When exposed to these items they may have a severe allergic response, also known as anaphylaxis.

Within moments after exposure, these people may have anxiety, a tight throat, shortness of breath, and low blood pressure. These serious symptoms require prompt medical care, as breathing may stop and death could occur. If you see someone having these problems, seek help by calling 911. Watch and assist the victim's breathing if needed.

If you have ever had such a reaction, it may recur if you become re-exposed. It is important to:
* talk to your healthcare provider about prior reactions,
* avoid the substance,
* wear an ID bracelet to alert medics,
* carry an adrenalin syringe, such as Epi-pen or Ana-kit, for self-treatment when necessary, and
* tell those you live or work with how to respond should you need help.

It is easy to avoid allergic shock with the proper training and preparation.
