What is an acute allergic reaction?
Acute allergic reaction occurs when the body responds to a certain substance by release of histamines. Symptoms of acute allergic reactions include sneezing, runny nose, rashes, swollen skin, hives and breathing problems. Symptoms often start within a few minutes after exposure. Acute allergy can occur when a person is exposed to common allergens such as pet, molluscs, peanuts, wheat and dairy products. A sudden, severe allergic reaction can be fatal for a person who has an attack.
Some people are genetically susceptible to acute allergic attacks. Early exposure to certain substances causing allergy can cause someone to develop a serious, lifelong allergy against it. However, the genetic component is clear because allergies tend to run in families. The body thinks that a harmless substance is a danger, so it creates a reaction designed to repel and destroy the perpetrators. If it is not treated, an acute allergic reaction may lead to death.
Some very serious allergic reactions require medical assistance. The hives and itchy eyes are not life -threatening, but if the airways are reduced, anaphylaxis may occur. This very serious symptom causes a person to faint and stop breathing. Auto-lens needle filled with epinephrine can sometimes prevent anaphylaxis, but is less effective if it is given after a person's performance. Epinephrine releases the neck and airways to allow breathing again.
Sometimes the allergic reaction can be checked by antihistamines. Loratadine, Cetirizin and Difenhydramine are over -the -counter medicines that block the production of histamine of the body and stop the exaggerated response of the body. Antihistamines are produced in the form of pills and liquid suspensions. Some antihistamines may take up to 24 hours and do not cause drowsiness. People who suffer from allergies usually carry antihistamos pills with them at all times.
If someone has an acute allergic reaction with the airway obstruction,He needs immediate medical attention. Medical or doctors have the tools necessary to prevent anaphylaxis. Pills or needles of epinephrine generally do not help at this point and over -the -counter medicines are not strong enough to fight this type of reaction.
people who suffer from serious allergies on certain substances should keep them away, because the best way to prevent reaction is to completely avoid allergen. Antihistamines collected before the exposure of allergens can help reduce the risk of anaphylaxis, but there is no certainty with these drugs. The only way to prevent reactions is to stay away from the substance causing allergy.
