AnswerAnaphylactic reactions are general, dramatic reactions that can result in collapse and possibly death. It is caused by a sudden release of histamines and other chemicals that overwhelm the body. The onset is usually quite rapid and symptoms occur within minutes. Death can potentially occur immediately or within two hours.

The first sign may be tightness of throat, swelling and redness of the skin or may be a non-visible internal reaction such as swelling of the airway, a drop in blood pressure, shock, or nausea. The allergic person may also have a feeling of great anxiety.

Immediate action is needed. Persons who know they are prone to these reactions (allergies to peanuts, shellfish, and insect stings can be of this type), should consult with their doctor about a small emergency kit to carry with them. This kit will usually have antihistamines and Epinephrine [The most common Epinephrine is the UK Epipen]. For this type of reaction, call for medical help [ambulance] immediately. Minutes are vital.

Standard treatments used to control the reaction are epinephrine, oxygen, and intravenous fluids. Antihistamines and corticosteroids can also be used. The person needs to be under medical supervision until the reaction is under control.

In other words, when you have an anaphylactic reaction(as a sufferer of one as well) it is when several reactions happens such as hives, wheezing rashes and suffercation. The person having the anaphylactic reaction will be in great pain but should be carrying an Eppipen which is a spring loaded shot of adrenaline.

Allergic reactions can also cause the throat to swell shut. Acute allergic reactions are called anaphylactic reactions and may be fatal. Strangulation puts external pressure on the trachea causing another form of choking.

People who are allergic to penicillin can experience allergic reactions in different ways. Some examples of an allergic reaction to penicillin can include: -hives -rash -itchy skin -wheezing -swelling of the lips, tongue, or face The most serious allergic reaction to penicillin is an anaphylactic response, which can be life-threatening. Anaphylactic reactions develop immediately after penicillin exposure in highly sensitive people. Anaphylactic reactions cause the airways to constrict and lower blood pressure. Signs and symptoms include: -constriction of the airways -shock associated with a marked decrease in blood pressure -weak and rapid pulse -hives and itching -dizziness or fainting -flushed or pale skin -nausea, vomiting, or diarrhea
