With an allergy, a rash: photo, treatment, prevention

With an allergy, the rash on the skin appears very often. About how this phenomenon looks like, and how to treat it, we will tell in the materials of this article.

Basic information

The term "allergy" refers to the hypersensitive state of the human immune system when repeated exposures of an allergen to the body previously sensitized them.

With an allergy, the rash may appear immediately or a few days later. It is necessary to treat such a condition. We will tell you how to do this below.

Causes of development

Why does the rash occur with allergies in children and adults? As it was said above, the considered reaction is a personal intolerance of this or that factor. Such an unpleasant symptom, as a rash, is a consequence of a specific reaction of human immunity.

Skin rashes for allergies can occur due to the following factors:

• Certain medicines;
• Such foods as nuts, honey, citrus fruits, dairy products, chocolate (most often an allergic rash due to food appears on the face);
• Some types of fabrics (for example, synthetic or wool);
• Chemical substances, including household chemicals;
• cosmetics;
• Animal hair;
• Pollen of plants;
• Some types of metals;
• Insect bites (a similar reaction is called an insect).

It should also be noted that the allergic rash, the photo of which is presented in this article, may even arise from the effects of cold.

Appearance

What does the rash look like with allergies? Such manifestations on the skin are characterized by the following features:

• The color of the spots can range from pink to bright red;
• Rashes on the covers usually do not have a clear shape (they are spots with blurred and fuzzy edges);
• In the place where the rash appears, peeling may occur;
• Most often a rash of allergic origin is similar to a nettle burn, although such rashes may also have the appearance of nodules, spots, wet bubbles and blisters;
• In the place of rash the skin is usually very irritated, sometimes it is swollen;
• Allergy due to food usually occurs on the face, particularly on the cheeks and around the mouth (also can be seen on the abdomen, arms, back, legs).

Where does it appear?

With allergies, the rash can be localized in various parts of the body. For example, irritation with contact dermatitis appears in the place where the skin has come into contact with the allergen. The reaction to household chemistry usually occurs on the hands, and on wool or synthetics, for example, when wearing trousers made of this material, only on the lower extremities. In other types of allergies, irritation can occur anywhere.

Few people know, but with allergies the rash does not always occur. Spots and dots on the body may not be. In some cases, this reaction is manifested only by redness and swelling. Usually, such a phenomenon is observed in pollinosis, that is, with allergy to pollen.

Concomitant allergic symptoms

Allergic rash is just one of several signs of intolerance to a certain allergen. In addition to skin irritation, such a pathological condition can be accompanied by other unpleasant phenomena. Usually they are:

• Suffocating cough;
• Tearing;
• Severe itching of the skin;
• Redness of the visual organs;
• Sneezing;
• Annoying cold;
• photophobia.

As for the rise in body temperature, then with an allergy such a symptom develops extremely rarely. Most often, this symptom does not arise because of the fact of allergy, but as a result of infection. For example, if a child has multiple bites on his hands, and he began to intensively comb them, he will eventually become infected.

If irritation on the skin really has an allergic etymology, then usually a person feels quite normal. At the same time, he does not experience any ailments. A rash with allergies in children can be a concern, but this is only a consequence of severe itching of the skin.

Other signs

How does the antibiotic allergy manifest itself? Rash on the skin (treatment of this condition should be carried out necessarily) when taking a medication is a drug urticaria. This reaction to the drug is called a side effect. Usually its possible appearance is warned in the instructions that are attached to many medications and even to multivitamin complexes. If the patient has an allergy to pollen, and this allergen has got into his digestive tract, then he may begin vomiting, nausea and severe pain in the abdomen.

When should I sound an alarm?

If an allergic rash (a photo of such an irritation you can find in this article) arose on the child's body, then it is necessary to measure his temperature. In this case, it is necessary to pay special attention to whether your baby has any problems with breathing. If it is difficult, then you should immediately contact a doctor, as this may indicate the development of such a serious complication as the swelling of Quincke.

Reasons to call a doctor

Types of rashes for allergies can be different. Such irritation can be localized in one place or cover the entire body. In any case, seeing a rash on the skin of incomprehensible origin, you should always contact a specialist. What is the reason for this urgency?

• If there is no necessary treatment, a rash with allergies can develop into a serious complication, for example, in bronchial asthma.
• Identify independently, what exactly served the development of such irritation, is rather problematic. In most cases, this requires a laboratory test. In order to determine the type of allergen, the doctor must make skin tests or send the patient to the blood test.
• Not always irritation of the skin indicates the development of an allergic rash. This phenomenon may be a symptom of an infectious disease (for example, rubella, chickenpox, herpes zoster and others). All these diseases are contagious and require constant monitoring by a specialist.
• A rash on the skin may be an ordinary dermatological disease (including depriving, psoriasis or eczema). It is extremely important to diagnose the disease at the initial stage of its development. Only in this case the treatment will be most effective.
• The rash that appears on the skin may result from a bite of insects. For example, after bite by an ixodic tick, irritation may not appear for quite a long time (from 2 weeks to 1 month). To reveal independently, that the reason for the appearance of spots was precisely the tick bite, it is very difficult. In this regard, you can skip the development of such a dangerous disease as borreliosis.

Even if the patient is fully confident that the rash on his skin is allergic in nature, her treatment should be conducted only by an experienced doctor. As a rule, special ointments are used to treat this condition. If the case is neglected and severe, the patient may need a whole complex of medicines.

How to get rid of the rash?

How much does the rash from allergies take? Independently, this irritation occurs only after contact with the allergen has been completely discontinued. Typically, it takes a few days or even weeks. If the patient does not know why such rashes have appeared on his skin, then he should consult a doctor. After the examination, the doctor will be able to make a hypoallergenic diet or teach the patient principles that will minimize contact with the established allergen.

Also, an allergic rash can be cured by immunotherapy. For this, the patient is given injections with a microdose of the allergen (sublingual drops can be used). To completely eliminate the allergic rash, it may take a rather long treatment, as a result of which a so-called "antidote" to the allergen is produced in the human body.

How is the antibiotic allergy treated? Rash on the skin, which should be treated only by an allergist, very often occurs after taking certain drugs. It is paradoxical, but various medications are used for its elimination. As a rule, they are intended for topical application (for example, preparations "Triderm", "Pimafukort" and others). Though the doctor can appoint them and in a combination to medicinal preparations for reception inside (for example, with "Clemastinum", "Tavegilom", "Suprastinum", "Loratadinum" and others).

How to treat allergies in children?

Allergic rash in children can occur for various reasons. When observing this irritation, you should remember what kind of food your child used in the last few hours. Very often the reason for the development of allergies in the baby is a detergent, previously unused in the family. Another reason for this phenomenon may be the taking of certain medicines or the replacement of baby porridge.

A child prone to allergic reactions should, if possible, refrain from contact with cosmetics, creams or soap. If irritation has already occurred, then to treat the baby using antihistamines. To prevent the subsequent appearance of a rash, it is necessary to protect children from an established source of an allergen. To determine it, you need to contact an allergist.

With this pathology, it is very important not to let the allergy "by chance". If you do not take any action, then this reaction can become more complicated and develop into asthmatic dermatitis, hay fever or bronchial asthma.

Prevention

What measures to take to prevent an allergic rash develop? To do this, you must follow the following rules:

• Pregnant women should take antibiotic drugs with extreme caution, and also follow a certain diet.
• Nursing mothers should not abuse foods that cause allergies (eg, chocolate, chicken eggs, fish, citrus fruits).
• Children born of allergy sufferers need to breastfeed longer.
• Babies suffering from food allergies should avoid the use of salty and spicy food, canned and marinated foods.
• Allergy sufferers should refrain from contact with animals and dust in the house.
