What are the 5 most common triggers for anaphylaxis?
Common anaphylaxis triggers include:
- foods – including nuts, milk, fish, shellfish, eggs and some fruits.
- medicines – including some antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin.
- insect stings – particularly wasp and bee stings.
- general anaesthetic.
Can you survive anaphylaxis without treatment?
This is a dangerous and life-threatening situation called anaphylactic shock. Symptoms of anaphylaxis can be mild, and they may go away on their own (most anaphylactic reactions will require treatment). But it’s difficult to predict if or how quickly they will get worse.
How fast does anaphylaxis happen?
Anaphylaxis can occur within minutes – the average is around 20 minutes after exposure to the allergen. Symptoms may be mild at first, but tend to get worse rapidly.
