Cross-allergy. Allergy to medicines. Types of allergies

Cross-allergy is a type ofmore precisely, the property of ordinary allergies. As is known, many stimuli have their counterparts. For example, if an allergen causes any negative reactions in a person, then it is likely that their existing counterpart or even a group of them will provoke them.

The essence of the relationship

Cross-allergy occurs due to the similarity of the structure of allergens in a set of amino acids. To understand how such a deviation manifests itself in real life, consider an example.

The person is allergic to dust. But one day he observes similar negative reactions in himself after eating shrimp. Thus, he has a cross-food allergy, similar to that caused by ordinary household dust. So why is this phenomenon possible? The fact is that the body of a given person simply confused the cells of dust and shrimp because of their incredible similarity. The difficulty of these situations lies in the fact that it is not always possible to find out what is the allergen-twin of the pathogen already familiar to you. However, the most common such relationships have already been calculated. Thanks to them, a special table of cross-allergy was compiled. Consider some of its parts in more detail.

Allergy to pollen

As a rule, such cross-allergy makes itself felt in the spring-summer season, when there is an active flowering of various plants and herbs. So, consider the doubles-allergens of ordinary pollen.

cross allergy to birch

  • Cross-allergy to birch (leaves, buds), as well as pollen of alder, hazel, apple and alder cones.
  • Intolerance to the pollen of all grasses and food grains (oats, barley, wheat, etc.).
  • Cross-allergy to wormwood, sunflower, dahlia, chamomile, dandelion, calendula, elecampane, string, coltsfoot.

Food Allergies - Food Pollen Doubles

Cross-allergy to birch and other plantsmay occasionally occur if a person develops negative reactions after contact with ordinary pollen. But this deviation applies not only to grass and trees. After all, often such a person is allergic to spores of fungi, as well as some types of food. The biggest mistake of patients is that very often because of their ignorance they don’t connect these seemingly distant allergens to each other.

  • Allergies to pollen of birch, hazel and alder intersect with allergies to hazelnuts, apricots, almonds, cherries, peaches, potatoes, kiwi fruit and celery.
  • Wormwood pollen - potatoes, red pepper, celery, chamomile, fennel, dill, cumin, coriander, as well as all drinks that make up the plant (vermouth and balsam).
  • Sunflower pollen - halva, sunflower oil, mustard and mayonnaise.
  • Ambrosia pollen - banana, melon.
    cross food allergies
  • Herb pollen - tomatoes, peanuts and melon.
  • Fragrant herbs - celery, various spices.
  • Latex - potatoes, banana, papaya, pineapple, avocado, chestnut, tomatoes, figs, spinach.
  • Pollen of weed meadow herbs - flower honey.

Food allergens and their counterparts

What types of allergies do you know? Food, vegetable, medicinal, etc. But such a division is only conditional. After all, a person often has only one of the above listed deviations, and the rest are all types of cross-reactions.

Thus, if the patient manifestsallergic to any food product, it is often impossible for him to use those ingredients that even contain a small proportion of similar irritants.

  • If a person is allergic to cowmilk, then, most likely, the same negative reactions will appear in him as a result of the consumption of products containing his proteins, as well as goat milk, beef, veal and meat products from them, enzyme preparations based on cattle pancreas, and after contact with the cow's coat.
  • Kefir or kefir yeast - yeast dough, mold fungi, penicillin-type antibiotics, mold cheeses, kvass and ordinary mushrooms
  • Sea and river fish - seafood (shrimps, crabs, mussels, caviar, lobster, lobster, etc.), as well as fish food.
  • Chicken eggs - duck meat, chicken broth and chicken, quail eggs, sauces, creams, mayonnaise, feather pillows, etc.

    drug allergy

  • Carrots - vitamin A, celery, parsley and beta-carotene.
  • Strawberries - lingonberries, raspberries, currants and blackberries.
  • Apples - pear, peach, quince and plum.
  • Potatoes - tomatoes, eggplants, green and red chilli peppers, tobacco and paprika.
  • Nuts - rice flour, kiwi, sesame, mango, poppy seeds, buckwheat and oatmeal.
  • Peanuts - soybeans, green peas, bananas, tomatoes, stone berries and fruits.
  • Bananas - melon, wheat gluten, latex, kiwi and avocado.
  • Tangerines - grapefruit, orange and lemon.
  • Red beet - white beet, sugar and spinach.
  • Legumes - mango, peanut, beans, soybeans, lentils and peas.
  • Plum - apples, almonds, nectarines, apricots, cherries, cherries, prunes, peaches, etc.
  • Kiwi - nuts, bananas, avocados, sesame, flour (buckwheat, rice, oatmeal), cereals, etc.

Allergy medication

If the patient is allergic to anythe drug, then, most likely, negative effects will also arise after the use of other medications, which also include a known irritant.

cross allergy table

It should be noted that drug allergiesis the most common among all others. And this is attributed to the fact that in the production of medicines very often synthetic components are used that are not perceived by the human body.

  • The drug "Penicillin" - all its derivatives.
  • The drug "Levomitsetin" - all its derivatives, including the drug "Sintomitsin", as well as their antiseptic solutions.
  • Sulfonamides (for example, the drug "Biseptol") - drugs "Novocain", "Anestezin", "Trimekain", "Dikain", etc.
  • The drug "Streptomycin" - all its derivatives and aminoglycosides.
  • The medicine "Tetracycline" - means "Metatsiklin", "Rondomitsin", "Morfotsiklin", "Olemorfotsiklin", "Glycocylin", etc.

Symptoms of Cross Allergy

As a rule, cross-allergy in adults andchildren do not leak unnoticed. Its manifestations are very similar to the symptoms of a normal allergy. These symptoms include rhinitis, tearing, itching and burning on the skin, swelling of the mucous membranes, bronchial asthma, urticaria, dermatitis, etc.


You can diagnose cross-allergy withmolecular assisted research. So, using special equipment, doctors detect the reaction of a person not to any product or plant, but to a specific protein that is included in their composition. In this way, and determine the existing twins.

How to treat cross-allergy?

Cross allergy therapy with virtually nothingno different from conventional treatment. The difference between them consists only in the fact that before the start of all necessary measures, the main allergen should be identified, which gives an impetus to the rest.

allergy in adults

During the treatment of this type of diseasemajor are antihistamine drugs. The following medications are among those that give the best effect: Claritin, Zertek, Cetrin, Erius, etc. The main advantage of these drugs is that they never have a negative effect on the central nervous system, as well as have no side effects. Although in some cases, the patient may experience drowsiness, dry mouth, constipation, urinary retention, etc.

As practice shows, to eliminatemanifested allergic reactions takes about one week. In more difficult cases, doctors recommend taking these drugs for several months.

Preventing Cross Allergy

What preventive measures to hold,to prevent the occurrence of cross-allergy, depends only on the primary pathogen. For example, if a person has regular allergic reactions to pollen, then when different plants and herbs bloom, it is recommended to avoid the places where they grow.

It should also be noted that wearing gauzedressings and sunglasses will help protect the mucous membranes of the person from possible irritation. In addition, wet cleaning in the house and careful personal hygiene will help minimize the number of possible contact with allergens.

The use of antihistamines is also a reliable way to prevent allergies, including cross-allergy.

If the patient has food allergies, then his usual menu should be well thought out. Thus, a person should exclude all probable stimuli from his diet.

In addition, in order to avoid manifestations of allergic reactions, the patient is advised to purchase only those cosmetics, on packages of which there is a “hypoallergenic” mark.
