- Vaccines
- Foods and food additives, especially eggs, peanuts, seafood, cow's milk, soy, and tree nuts
- Blood products
- Latex products (eg, gloves, medical tubing, condoms)
Allergic Reaction to Medication (Hives)

Some triggers, like dyes used in x-ray procedures, can cause a reaction similar to anaphylaxis.
Risk Factors
These factors increase your chance of developing anaphylaxis. Tell your doctor if you have any of these risk factors:
- Previous mild allergic reaction to the substances listed above
- History of eczema , hay fever , or asthma
- Children who have certain conditions, such as spina bifida and urogenital defects (due to the heavy exposure to latex they have during multiple surgeries)
