anaphylaxis symptoms
Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock â your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting. Common triggers include certain foods, some medications, insect venom and latex. Anaphylaxis requires an injection of epinephrine and a follow-up trip to an emergency room.
