Anaphylaxis is a severe allergic reaction to venom, food, or medication. Most cases are caused by a bee sting or eating foods that are known to cause allergies, such as peanuts or tree nuts. Anaphylaxis causes a series of symptoms, including a rash, low pulse, and shock, which is known as anaphylactic shock.
Signs and symptoms include:
- Skin reactions, including hives and itching and flushed or pale skin.
- Low blood pressure (hypotension)
- Constriction of your airways and a swollen tongue or throat, which can cause wheezing and trouble breathing.
- A weak and rapid pulse.
- Nausea, vomiting or diarrhea.
- Dizziness or fainting.

what is the difference between anaphylaxis and anaphylactic shock?
The terms “anaphylaxis”and “anaphylactic shock“are often used to mean the same thing. They both refer to a severe allergic reaction. Shock is when your blood pressure drops so low that your cells (and organs) don’t get enough oxygen. Anaphylactic shock is shock that’s caused by anaphylaxis.
What does anaphylactic shock look like?
The first signs of an anaphylactic reaction may look like typical allergy symptoms: a runny nose or a skin rash. Hives; a rash; and itchy, swollen, or red skin. Runny or stuffy nose and sneezing. Shortness of breath or trouble breathing and rapid heartbeat.
Can anaphylaxis happen slowly?
The symptoms of anaphylaxis can vary. In some people, the reaction begins very slowly, but in most the symptoms appear rapidly and abruptly. The most severe and life-threatening symptoms are difficulty breathing and loss of consciousness.
How do you treat anaphylaxis at home?
Do the following immediately: Call 911 or emergency medical help. Use an epinephrine autoinjector, if available, by pressing it into the person’s thigh. Make sure the person is lying down and elevate his or her legs. Check the person’s pulse and breathing and, if necessary, administer CPR or other first-aid measures.
Can you have a mild anaphylactic reaction?
Anaphylaxis is defined by a number of signs and symptoms, alone or in combination, which occur within minutes, or up to a few hours, after exposure to a provoking agent.

What happens to the body during anaphylaxis?
During anaphylaxis, small blood vessels (capillaries) begin to leak blood into your tissues. This can cause a sudden and dramatic drop in blood pressure. When major organs don’t get the blood and oxygen they need to function, your body goes into anaphylactic shock.
How fast does anaphylaxis happen?
Anaphylaxis can occur within minutes – the average is around 20 minutes after exposure to the allergen. Symptoms may be mild at first, but tend to get worse rapidly. Typical symptoms and signs may include: Facial swelling, including swelling of the lips and eyelids.
What are the 4 types of allergic reactions?
Type I: Immediate Hypersensitivity (Anaphylactic Reaction) These allergic reactions are systemic or localized, as in allergic dermatitis (e.g., hives, wheal and erythema reactions). Type II: Cytotoxic Reaction (Antibody-dependent) Type III: Immune Complex Reaction. Type IV: Cell-Mediated (Delayed Hypersensitivity)
Will Benadryl stop anaphylaxis?
Seek emergency treatment right away. An antihistamine pill, such as diphenhydramine (Benadryl), isn’t sufficient to treat anaphylaxis. These medications can help relieve allergy symptoms, but work too slowly in a severe reaction.
How long after bee sting can anaphylaxis occur?
In very rare cases, reactions develop after 24 hours. Anaphylaxis is a sudden and severe allergic reaction that occurs within minutes of exposure. Immediate medical attention is needed for this condition. Without treatment, anaphylaxis can get worse very quickly and lead to death within 15 minutes.
What is the gold standard of treatment for anaphylaxis?
The gold standard in management of anaphylaxis is thought to be the rapid and early administration of epinephrine by intra-muscular route. The prevention of anaphylaxis remains the treatment of choice.
How can you tell the difference between an allergic reaction and anaphylaxis?
A major difference between anaphylaxis and other allergic reactions is that anaphylaxis typically involves more than one system of the body. In some cases, however, it may take more than an hour to notice anaphylactic symptoms. Warning signs may include: Red rash (usually itchy and may have welts/hives)
Which drug can reverse the effects of anaphylaxis?
Can stress cause allergy attacks?
A new study shows that even slight stress and anxiety can substantially worsen a person’s allergic reaction to some routine allergens. Moreover, the added impact of stress and anxiety seem to linger, causing the second day of a stressed person’s allergy attack to be much worse.
