Medications, insect stings and food are major causes of anaphylactic shock. But, while allergies are often experienced within minutes of the food or drug intake or a sting from a bee, there are also cases of late reactions. Delayed anaphylactic shock is one example.
Delayed anaphylactic shock is a type of anaphylactic shock. It can manifest after 3 to 6 hours. Studies at University of Virginia cite that delayed anaphylactic shock is in particular only for meat allergy (beef, pork and lamb). However, delayed anaphylactic shock can also occur in medications.
