- Anaphylaxis is most often caused by foods, medicines or insect stings. It can be caused by other things, such as latex or exercise.
- Reactions are unpredictable, but usually occur within a few minutes after contact.
- Anaphylaxis almost always occurs within an hour after contact, but can happen up to 2 hours later.
- Antihistamine medicines will not prevent or stop anaphylaxis.
- Anaphylaxis is a medical emergency. Death can occur.
Asthma And Anaphylaxis
- Anaphylactic reactions can be worse if you also have asthma, especially if asthma is not well controlled.
- Trouble breathing can occur with both asthma and anaphylaxis. Asthma symptoms usually get worse over days. Breathing problems due to anaphylaxis will come on quickly, within minutes.
- Asthma inhalers will not work for anaphylaxis.
- Adrenalin (epinephrine) is needed to treat anaphylaxis.
