Sneezing, nasal congestion, postnasal drip and skin rashes are all signs of allergies that can be triggered by environmental pollen, certain foods, insect bites, certain medications and substances such as latex. Sometimes, allergic reactions can be left untreated and will resolve once the trigger is removed. But unfortunately, complications can arise when allergies are left untreated. However, certain medications like antihistamines and decongestants purchased at a local pharmacy can treat more serious allergy symptoms.
Anaphylaxis
Allergies can lead to anaphylaxis, a potentially fatal medical condition that results when severe allergy symptoms are untreated. Symptoms of anaphylaxis include wheezing, nausea, vomiting, nasal congestion and trouble breathing. Diarrhea, confusion, slurred speech, red skin, a pounding heartbeat, stomach pains or cramping, dizziness and a cough are other anaphylaxis symptoms, says MedlinePlus.
Typically, certain medications like morphine, certain foods and insect bites can lead to anaphylaxis.
Call 911 in the event of an anaphylactic reaction. Medical responders will give an epinephrine injection to dilate the airways. Sometimes, a breathing tube may be inserted if cardiopulmonary resuscitation (CPR) is unsuccessful. Antihistamines such as diphenhydramine and corticosteroids such as prednisone are other treatments of anaphylaxis.
Asthma
Allergies can also elevate the risk of getting asthma, an airway inflammatory disorder characterized by shortness of breath, wheezing and a cough, says MedlinePlus. Anxiety, sweating, a rapid pulse, chest pain, nasal flaring (enlarged nostrils) and chest tightness are asthma's other characteristics.
The following are asthma triggers: dust, pet dander, tobacco smoke, stress, exercise, mold, cold weather and pollen.
Treating asthma involves taking such medications as inhaled corticosteroids, bronchodilators, cromolyn sodium, aminophyline and methylprednisolone to either decrease inflammation or dilate the airways so that easier breathing can occur. A persistent cough, the need for a mechanical breathing machine (ventilator), lack of sleep and even death can occur if asthma is left untreated.
Atopic Dermatitis
Allergies also increase the risk of getting atopic dermatitis. According to the National Eczema Association (NEA), symptoms of atopic dermatitis include inflamed and itchy skin that affects the elbows, hands, knees and face. The NEA states that certain triggers like stress, allergens, sweating, heat and infections can cause atopic dermatitis.
Simply using moisturizing lotions or creams found at a local drugstore can treat atopic dermatitis. Also, using warm water while showering and not scrubbing the skin can decrease the risk of getting the condition.
