There is often very little time for an allergy victim to react to an attack once it happens because it is often sudden and very serious. Allergens in the environment cause uncomfortable symptoms in a person which in turn result in an allergic reaction.

Allergies vary from skin rashes to hives, itching to sneezing, or watery eyes as a result of exposure to dogs, cats, bee stings, dust, dust mites, trees, weeds, molds, and foods, such as nuts, strawberries, and shellfish. People who react more aggressively develop swelling of their tongue, wheezing, breathing seizures, tightness in the chest, vomiting or even unconsciousness.

Patients have been known to lapse into anaphylactic shock and sometimes sudden death if they fail to get medical help within fifteen minutes of a very violent allergic reaction. Immediate allergic reactions occur just like reactions that occur as many as twenty-four hours after exposure.

The more the exposures to an allergen, the more severe a reaction is likely to be, even if the exposure becomes less. Treatment or symptom suppressants for more common allergies include antihistamines and decongestants, or extra measures like asthma treatments or immune building processes.

As long as it is possible, shellfish, poison ivy, peanuts and bee stings that cause severe allergic reactions when exposure occurs, ought to be avoided. Inadvertent contact with an allergen can cause brutal allergic reactions and has prompted some adults and children who have experienced this to always carry an Epi-Pen.

The Epi-Pen comprises a pre-filled syringe that contains epinephrine for instant administration. By simply pulling off the needle guard, the substance in the Epi-Pen is ready for injection into any large muscle such as the thigh. The Epi-Pen does not need for you to remove clothing, thereby wasting time before applying.

It is imperative to closely watch someone who is having an allergic reaction. Should the person fail to show signs of improvement after five minutes of administering the Epi-Pen, call a doctor.
