Allergic Reactions Information

Some allergic reactions are very serious or even fatal and they can occur almost instantly leaving little time to react. Allergic reactions occur when a person who is sensitive to an allergen experiences uncomfortable symptoms. Common allergens that trigger allergic reactions symptoms are dogs, cats, bee stings, dust, dust mites, trees, weeds and molds. People can also be allergic to foods such as nuts, strawberries, and shellfish, which usually start to react within seconds of exposure and can cause mild to moderate reactions including skin rashes, hives, itching, sneezing, or watery eyes. More moderate to severe allergic reactions include difficulty breathing, swelling of tongue, wheezing, nausea/vomiting, abdominal pain, chest pain or tightness and even unconsciousness. Acute anaphylactic allergic reactions happen suddenly and progress rapidly; treatment must be administered within fifteen minutes, if not anaphylactic shock can be fatal.

Most allergic reactions occur quickly but some may take up to a few hours, they do not usually occur after twenty-four hours from exposure. Allergic reactions tend to be more severe when exposure to an allergen is repeated on different occasions, and each time it requires smaller and smaller amounts of the allergen to cause symptoms. In most cases of environmental and pet allergies, simply taking an antihistamine such as Benadryl, and/or a decongestant will relieve symptoms, and some people also may require immunotherapy and asthma treatment in addition to these medications. Substances like shellfish, poison ivy, peanuts, and bee stings should be avoided whenever possible, because more severe reactions usually result when exposure occurs. Some adults and children who have experienced severe allergic reactions in the past must carry an Epi-Pen in case of accidental exposure. The Epi-Pen contains epinephrine and comes in a pre-filled syringe ready for emergency administration. Simply pull off the needle guard and inject into a large muscle, such as the thigh. The Epi-Pen can be administered right through clothing so there is no need to waste valuable time trying to remove someone's clothes.

After an allergic reaction has begun it is very important to monitor the person. If symptoms do not subside within five minutes and they continue to worsen even after administration of an Epi-Pen, emergency treatment should be sought immediately.

Allergic reactions are quite common and it is important that people know what to do in the event that one occurs to themselves or someone else – it could be a matter of life or death.
