Allergic Reactions
Immune responses to allergens causing various symptoms, mild to severe.
Allergic reactions occur when the immune system responds to foreign substances, such as pollen, food, insect stings, or medications, that are generally harmless to most people. These reactions can vary in severity from mild symptoms like itching, hives, and nasal congestion to severe, potentially life-threatening conditions known as anaphylaxis. Anaphylaxis can cause symptoms such as difficulty breathing, swelling of the throat and tongue, rapid pulse, and a drop in blood pressure.
Immediate treatment is crucial for anaphylactic reactions, typically involving the administration of adrenaline (epinephrine) via an auto-injector. Antihistamines may be used for milder reactions to alleviate symptoms. Following the initial management, it is essential to seek emergency medical assistance to ensure the reaction is fully treated and monitored.
Rashes
Itching
Swelling
Difficulty breathing, sneezing
Anaphylaxis
Remove the allergen if possible
Apply a cold compress to reduce swelling
Use over-the-counter antihistamines for mild reactions
Seek medical help if symptoms worsen or do not improve
Allergic reactions occur when the immune system overreacts to a substance (allergen) that is normally harmless. Symptoms can range from mild (rashes, itching, and swelling) to severe (difficulty breathing, anaphylaxis). Common allergens include certain foods, insect stings, medications, pollen, pet dander, dust and latex.
