Anaphylaxis is a potentially life-threatening allergy response. Allergies to prescription medications, latex, insect stings, and certain foods are the most often associated with anaphylaxis. An anaphylactic reaction causes throat swelling and trouble breathing, low blood pressure, dizziness, rapid heartbeat, and potentially even cardiac arrest if left untreated. If you begin experiencing anaphylaxis, it is important to seek immediate medical attention or administer epinephrine. Anaphylaxis can occur immediately after exposure to an allergen, but a biphasic reaction (a second anaphylactic reaction) can occur as many as 12 hours after the initial reaction occurs, so it is important to be vigilant of any potential symptoms.
