What should you know about sesame food allergy?

Symptoms may include hives, swelling of the lips or face, vomiting, stomach cramps, wheezing, coughing, or an itchy throat. A reaction can begin soon after eating sesame, but the pattern and intensity can vary between exposures.

Sesame may be present in seeds, tahini, hummus, breads, crackers, dressings, and mixed foods. Read ingredient lists carefully and ask about preparation when eating food made by someone else. An allergy clinician can assess the history and may arrange Allergy Testing.

Stop eating the food and keep the packaging if available. Follow your personalised emergency plan. If prescribed adrenaline, use it as instructed for a severe reaction and contact emergency services; do not wait to see whether symptoms settle.

For milder symptoms, contact a clinician for advice rather than testing foods at home. Avoid deliberate re-exposure until an assessment has clarified the trigger. A written plan can help family, school, or workplace staff respond consistently.

Call emergency services immediately for trouble breathing, throat tightness, a hoarse voice, faintness, collapse, or symptoms affecting more than one body system. These may indicate Anaphylaxis, which needs emergency treatment.

Seek prompt medical advice for a first reaction, facial swelling, repeated vomiting, or an itchy throat that is worsening. Emergency teams can provide Anaphylaxis Emergency Treatment and observation after a serious reaction.

Ask whether the reaction fits sesame allergy, which foods or labels need extra caution, whether you need an adrenaline device, and how relatives or colleagues should use your emergency plan.
