Medications are the most common cause of anaphylaxis, which is a severe and potentially life-threatening allergic reaction. Treatment involves the use of epinephrine auto-injectors, which are critical for patients with severe allergies to carry at all times.

The nurse understands that the most common cause of anaphylaxis is medications. While food allergies, insect stings, and latex can also trigger anaphylaxis, medications are particularly associated with severe allergic reactions. Anaphylaxis is a life-threatening emergency that can result in anaphylactic shock, characterized by a dramatic drop in blood pressure and contractions of bronchial smooth muscle due to systemic mast cell degranulation.

This can happen when allergens are ingested, as in the case of certain foods like shellfish and peanuts, or when they are injected, as with bee stings or medication like penicillin. Treatment for anaphylaxis typically includes the administration of epinephrine, which raises blood pressure and relaxes bronchial smooth muscle, thereby counteracting the effects of systemic allergic reactions. Epinephrine auto-injectors are lifesaving devices that patients with known severe allergies should carry at all times.

In summary, when considering foods, insect stings, medications, and latex as potential allergens, medications are the prime cause of anaphylaxis. It is essential for individuals with severe allergies to have immediate access to epinephrine to mitigate the symptoms of anaphylactic shock.
