Anaphylaxis

Anaphylaxis is an extreme and rapid allergic reaction that affects multiple body systems and is considered a medical emergency. It occurs when a pet's immune system overreacts to an allergen, such as an insect sting, certain medications, or vaccines, causing a sudden release of chemicals. Symptoms can appear within minutes to hours and may include sudden weakness, collapse, vomiting, diarrhea, swelling of the face or muzzle, hives, pale gums, rapid heart rate, and severe difficulty breathing. Without immediate veterinary intervention, anaphylaxis can be fatal. Treatment typically involves injectable medications like epinephrine, antihistamines, and corticosteroids to counteract the allergic response and support vital functions. If you suspect your pet is having an anaphylactic reaction, seek emergency veterinary care immediately.
