Allergic Reactions
What is an allergic reaction?
An allergic reaction is the hypersensitive response of an individual’s immune system to an irritant.
When a normally harmless substance (allergen) enters the body, it can cause the body’s immune system to attack the allergen, creating an adverse (allergic) reaction. Common allergens include:
- Animal dander
- Bee/wasp stings
- Certain medications such as penicillin
- Dust mites
- Foods (particularly peanuts, tree nuts, fish, shellfish, eggs, milk, wheat, and soy)
- Insect bites
- Latex or other materials you touch
- Mold
- Plants and pollen
What are the symptoms of an allergic reaction?
During an allergic reaction, your immune system releases antibodies. These are proteins that deliver a message to cells to attack and remove the foreign substance. The cells then send out histamine, which causes blood vessels to expand, and other chemicals, which trigger the allergy symptoms.
An allergic reaction might range from mild and annoying to severe and even life-threatening.
How are allergic reactions prevented?
Working with a doctor to create an allergy management plan can help you control the severity and frequency of an allergic reaction. Your strategy depends on your type of allergy. Here are some ways to manage you allergies:
Avoid your allergens
This is very important but not always easy. Some allergens are easier to avoid than others. When you cannot avoid an allergen, try to reduce your contact with it.
Take your medicines as prescribed
They can be helpful for managing your symptoms. Take them while also avoiding allergens.
If you are at risk for anaphylaxis, keep your epinephrine auto-injectors (EpiPen) with you at all times.
Epinephrine is the only treatment for a severe allergic reaction. It is only available through a prescription from your doctor. Most epinephrine prescriptions contain two auto-injectors (pens) in a set.
Keep a diary
Track what you do, what you eat, when symptoms occur and what seems to help. This may help you and your doctor find what causes or worsens your symptoms.
Wear a medical alert bracelet (or necklace)
If you have ever had a severe allergic reaction, please wear a medical alert bracelet. This bracelet lets others know that you have a serious allergy. It can be critical if you have a reaction and you are unable to communicate.
Know what to do during an allergic reaction
Have a written anaphylaxis emergency action plan and keep is near you. It tells you and others what to do in case you have allergic symptoms or a severe allergic reaction. Always ask your doctor if you have any questions.
