There are many substances that can cause an allergic reaction, and they vary from person to person.
Allergic Rhinitis – This is often known as hay fever, and it may occur throughout the year or seasonally. It can be caused by indoor and outdoor allergens, such as pollen, dust and dander, and it can often be treated with an over-the-counter antihistamine. Symptoms of allergic rhinitis include sneezing, watery eyes, itching and asthma.
Drug Allergy – A drug allergy may be caused by prescription or over-the-counter medications. Most reactions are not truly drug allergies but are caused by sensitivity to the medication. However, there are a few drugs that can cause an allergic reaction.
Vaccine Allergy – While some people may be allergic to a vaccine itself, most are allergic to an ingredient in the vaccine, such as neomycin or eggs.
Antibiotic Allergy – Allergic reactions to antibiotics are frequently caused by antibiotics that contain sulfonamides. Some people are also allergic to penicillin, which means that they will also be allergic to antibiotics that are closely related to penicillin.
Food Allergy – A food allergy is not the same as a food intolerance, which is when the body’s reaction to a food is not caused by the immune system. Food allergies are often caused by an allergy to wheat, eggs, shellfish or berries. Symptoms of a food allergy include wheezing, swelling of the throat or tongue, hives or abdominal pain.
Exercise-Induced Food Allergy – This allergic reaction is triggered by certain foods that are eaten before exercising. The allergy may result in feeling lightheaded or itchy.
Pollen-Food Allergy – If a person has allergic rhinitis, he might also be allergic to fruits or nuts that contain similar allergy-inducing proteins. This allergic reaction may cause the throat to swell and may result in anaphylaxis.
Anaphylaxis – Anaphylaxis occurs when an allergic reaction is life-threatening. It may result in difficulty breathing or swallowing, feeling flushed, a drop in blood pressure or vomiting. Anaphylaxis may be caused by insect stings, food allergies or medications.
When to Seek Medical Attention
Many people who suffer from allergic reactions can alleviate their symptoms by taking an over-the-counter antihistamine. However, if an antihistamine is not providing you with relief or if your allergies are severe enough that they interfere with your quality of life, you may want to see a physician.
