In short

An allergy is a reaction by the immune system to substances that do not bother most other people, such as pollen, dust mites, mold spores, pet dander, food, insect stings, and medicines. In most allergic reactions, the immune system is responding to a false alarm, and genes and the environment probably both play a role. Allergies can cause symptoms such as a runny nose, sneezing, itching, rashes, swelling, or asthma, and they can range from minor to severe, including life-threatening anaphylaxis. Doctors use skin and blood tests to diagnose allergies, and treatments include medicines, allergy shots, and avoiding the substances that cause the reactions.

Normally, your immune system fights germs. It is your body's defense system. In most allergic reactions, however, it is responding to a false alarm. Genes and the environment probably both play a role.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.

Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.

What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.

Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.

In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
