Cross allergy (Cross-reactivity)
Cross allergy is caused by hypersensitivity to one or more substances. Cross-reactivity occurs when the proteins in one substance are like the proteins in another. As a result, the immune system sees them as the same and triggers an allergic reaction.
Appotek can advise you on symptoms and refer you to a specialist for treatment.
Symptoms
Cross allergy symptoms vary depending on which allergy is triggered. It is common to get symptoms such as itching, swollen lips and throat irritation, but you can also get stomach upset, nausea, vomiting and diarrhea. Some also get hives, eczema, sneezing and itchy eyes.
Causes
Cross allergy is caused by the immune system reacting to substances that are similar to those you are already allergic to. Here are some common allergens and the cross allergies they can trigger:
Birch pollen
- nuts
- pear
- plums and cherries
Grass pollen
- peanut
- cereals, such as oats and wheat
- tomato
mugwort pollen
- Curry
- Carrot
- pepper
Latex
- different fruits
- tomato
- seafood
Prevention and Protection
Avoid foods that you notice cause a cross reaction. Be sure to check what different foods contain. Those with a pollen allergy will have more cross reactions during pollen season. Do not forget to take allergy medicine.
There are various prescription drugs that help with allergies at the pharmacy. Ask your doctor which medicine will help you best.
Treatment
There are prescription drugs to treat allergies. A doctor will prescribe these after individual assessment.
When to consult a doctor
Seek care if you have major problems or if you have been treated with prescription drugs for two weeks without getting better.
