Antihistamines are the class of drugs that block histamine receptors and are used to treat allergic reactions. 'Histamines' are the inflammatory chemicals that cause allergy symptoms, 'histamine inhibitors' is not the standard terminology, and 'antimetabolites' are cancer/immune-suppressing drugs unrelated to allergy treatment. Antihistamines work by blocking the H1 histamine receptors to prevent allergic symptoms.

According to CDC and allergy organization data, approximately 100-150 Americans die annually from anaphylactic reactions to stinging insect venom (bees, wasps, hornets, fire ants). The 150 figure represents the upper end of documented fatalities from these severe allergic reactions. Lower numbers underestimate the actual public health impact, while higher numbers are unsubstantiated.

Allergic conjunctivitis is a well-recognized condition where allergens cause inflammation of the conjunctiva (the membrane lining the eyelids and covering the white of the eye), causing redness, itching, and tearing. This is commonly associated with allergic rhinitis ('hay fever') and represents one of the standard manifestations of allergic disease affecting the eyes.

Viral upper respiratory infections (colds) typically produce colored (yellowish/greenish) nasal discharge as the immune response progresses, while allergic rhinitis usually produces clear, watery mucus. The other options are incorrect: allergies often cause repetitive sneezing; neither colds nor allergies typically cause fever in adults; and anaphylactic shock is a severe allergic reaction, not a cold symptom.

Dander refers to microscopic flakes of skin shed by animals, not hair. These tiny particles become airborne and trigger allergic reactions in sensitive individuals. Option A incorrectly describes dander as hair, while option D describes settled dust, not dander itself.

Gluten is a protein found in wheat, rye, and barley. A gluten allergy means reacting to these specific proteins. Option B is incorrect because celiac disease is an autoimmune disorder, not an allergy - they're different conditions even though both involve gluten.

Allergies are diagnosed through clinical testing including blood tests (measuring IgE antibodies) and allergy skin tests (introducing small amounts of allergens to the skin). Both methods are valid diagnostic tools, and doctors often use them together.

Urticaria is the medical term for hives - itchy, raised welts on the skin that result from allergic reactions or other triggers. Options A and B refer to other skin conditions (atopic dermatitis and eczema are related but different), while folliculitis is a hair follicle infection.
