Dimetindene maleate, a phenindene derivative, is a histamine antagonist at the level of H1 receptors. It has antikinin, weak anticholinergic and sedative effects. It has no antiemetic effect. Reduces increased capillary permeability associated with immediate allergic reactions. In combination with antagonists of histamine H2 receptors, it inhibits almost all types of histamine effects on the circulatory system.

The half-life is about 6 hours. At concentrations from 0.09 to 2 μg/ml, the binding of dimethindene to plasma proteins is approximately 90%.

Children with skin allergies, diabetes mellitus, rickets, seborrheic dermatitis or frequent diarrhea are also at risk.

• non-compliance with normal temperature conditions;
• too hot, tight clothes or shoes that do not allow air to pass through and do not create natural ventilation;

Classification of the disease

There are four main types of miliaria, which differ in the nature of the rash, the duration of development and the severity of symptoms:

• Crystalline. It is accompanied by the development of a blistering rash, which most often appears on the head, behind the ears, and on the neck. Other localization of rashes is also possible. 2-3 days after the appearance, the blisters dry out and begin to peel off. Since irritation is not accompanied by inflammation or infection, the crystalline form is the simplest and most harmless.
• Red. A more complex type, in which sweat acts on the skin for a longer time and, accordingly, causes more severe irritation. A rash in the form of small inflamed tubercles provokes slight swelling and is accompanied by itching, burning, and discomfort. Lasts about two weeks.
• Miliaria alba, or vesiculopustulosis. With this type, blisters with a whitish or yellowish filling appear on the skin. When the bubble bursts, it leaves behind a light coating. The presence of color in the bubbly fluid indicates that the rash is accompanied by an infection, often staphylococcal.
• Deep. In most cases, prickly heat causes only superficial damage to the skin. With a deep form of pathology, the deep layers of the skin are affected. The disease is accompanied by blisters filled with light contents, which resolve or burst spontaneously.

Drug interactions Fenistil drops

When taken in combination, a mutual enhancement of the sedative effect of Fenistil drops and drugs that depress the central nervous system, such as tranquilizers, hypnotics and alcohol, is possible. With simultaneous consumption of alcohol, a more pronounced slowdown in the speed of psychomotor reactions is possible. When taken together with MAO inhibitors, it is possible to enhance the anticholinergic activity of antihistamines, as well as enhance their inhibitory effect on the central nervous system; therefore, their combined use is not recommended. Tricyclic antidepressants and anticholinergics may have additive anticholinergic effects when combined with antihistamines.

How to distinguish heat rash in a child from allergies and other diseases

When a rash appears on the skin, the most difficult thing for parents is to distinguish prickly heat from other diseases: allergies, chicken pox, measles, etc.

First, you should examine the location of the rash. In the first case, the rashes are located in hard-to-reach places: in the area under the diaper, in the folds of the skin, in the hairline. In this case, the rash almost never appears on open areas of the skin that are well ventilated. But if the rash appears on the face, open parts of the arms and legs, most likely it is an allergy.

A simple home test will also help make a differential diagnosis. You just need to undress the baby and leave him without clothes or a diaper for several hours. If the rash appears as a result of prickly heat, during this time it will decrease and become paler. If it is an allergy, no changes will occur to it.

Additional symptoms will help distinguish the disease from measles, chickenpox and other viral pathologies. With infectious diseases, the temperature always rises, intoxication appears, and the rash quickly spreads throughout the body. In turn, the main symptom of prickly heat is just a rash.

Overdose of the drug Fenistil drops, symptoms and treatment

In case of an overdose of Fenistil drops, like other antihistamines, the following symptoms may occur: central nervous system depression, drowsiness (mainly in adults), central nervous system stimulation and anticholinergic effects (especially in children), including agitation, ataxia, tachycardia, hallucinations, tonic or clonic convulsions, mydriasis, dry mouth, facial flushing, urinary retention and fever; arterial hypotension is possible. In the terminal stage of coma, depression of the respiratory and vasomotor centers may develop, leading to death. There is no specific antidote for an overdose of antihistamines. Standard measures should be taken: induce vomiting; if this fails, perform gastric lavage, take activated charcoal, saline laxative, and also take measures to maintain the function of the cardiovascular and respiratory systems. Vasoconstrictors can be used to treat arterial hypotension.

Symptoms

The main and most obvious symptom of the pathology is a rash. Most often, rashes appear on the head, chest, back, groin, armpits, and buttocks. The rash appears as scattered blisters with clear, white or yellow contents, or as small grains with an inflammatory outline.

During the day, the rash may intensify or decrease, and the severity of its manifestation depends on changes in temperature and care for the baby’s skin. In some cases, the child does not show concern, but sometimes may experience itching, pain and demonstrate discomfort with whims, unstable sleep, and lack of appetite.

In mild forms of the disease, other symptoms may not occur. But in more advanced cases, which are accompanied by complications and infection, clinical manifestations may be supplemented by:

• elevated temperature up to 38 degrees;
• the appearance of light plaque, ulcers, ulcers;
• the formation of weeping cracks with an unpleasant odor;
• general deterioration of condition.

When assessing symptoms, it is important to prevent the development of advanced forms of prickly heat and consult a doctor promptly, without waiting for complications to develop. Source: Skin care for a newborn. Solntseva O.A. Medical Council, 2014. p. 35-39.

What to feed a child with atopic dermatitis

In order not to provoke an exacerbation of dermatitis, to relieve itching and redness of the skin, you need to follow a diet. Foods that burden the immune system are excluded from the children's diet: citrus fruits, chocolate, eggs, honey, seafood. Red (strawberries, cherries, currants, apples) and exotic (mangoes, coconuts, pineapples) fruits are dangerous.

Split meals are recommended: small portions every 3-4 hours. It is better to boil, stew, bake, but not fry. Do not use spices, black pepper. The diet should be balanced and contain enough protein, vitamins, and microelements.

Avoid giving your child sugary carbonated drinks, chips, crackers and other snacks for as long as possible. If the infant is receiving breast milk, introduce new foods carefully. Add the product once a week to make sure it doesn't cause breakouts. After meals and between meals, offer your baby clean boiled water.

How to choose products that are right for your child

A dermatologist may recommend not one, but several drugs to choose from. They have a similar mechanism of action, but their prices may differ significantly. It depends on the active and auxiliary substances, manufacturer, and release form. When choosing a cream for a child’s atopic skin, you need to take into account possible individual intolerance to individual components.

You need to purchase drugs from well-known manufacturers with a good reputation: Russian, European, American. It is equally important to contact large pharmacy chains that work directly with manufacturers and control the quality of drugs on sale - this will protect you from purchasing counterfeit drugs. Consider the age of the child: choose creams and gels with a pleasant smell so that the child enjoys going to the shower.v

When choosing drugs for oral administration, it is preferable to buy syrups, powders, drops, rather than tablets and capsules that are difficult for a child to swallow.

Skin care

To relieve itching and prevent infection of the affected skin, you need to properly care for your skin:

• It’s better not to take a shower, but to take a cool bath for about 10 minutes; use medicated bathing products with a soft base that cleanse but do not dry the skin;
• moisturizing and softening – the skin should not be dry to prevent flaking and cracking; regularly apply a moisturizer recommended by a dermatologist;
• Do not let your child scratch the affected areas to avoid infection - apply anti-itching products to the atopic areas.

Cream or gel relieves discomfort during an exacerbation and allows you to sleep, eat, and play peacefully. Apply the drug to cleansed skin, treat atopic lesions and the areas around them. Do not exceed the recommended dosage and frequency of use.

Prevention

Atopy is translated from Latin as strangeness. The causes of the disease cannot always be determined. But long-term observation of patients and members of their families has revealed that it develops more often:

• with a genetic predisposition - if the parents are healthy, the probability of developing dermatitis in the child is 20%, if one of them is sick - 50%, if both are sick - 80%;
• in case of unfavorable pregnancy, active or passive smoking of the expectant mother, consumption of food that provokes allergy attacks, use of certain medications;
• when a newborn is in a dusty room, insufficient care for his personal hygiene;
• with prolonged exposure to allergens that enter the child’s body with food through the respiratory tract.

Breastfeeding for up to 6 months and avoiding allergy-provoking foods reduces the likelihood of developing atopic dermatitis.

Diagnostics

You should not self-medicate or try to diagnose your child yourself. Before you begin to treat prickly heat in a child, when the first rash appears, you should contact a pediatric dermatologist or pediatrician. The specialist will conduct an examination and distinguish the pathology from other diseases that are accompanied by a skin rash. For an experienced pediatric specialist, this is not difficult even with an initial visual examination.

In some cases, additional examination is necessary for a comprehensive diagnosis. The doctor may prescribe scraping for pathogenic fungal infections, as well as bacterial culture for microflora.
