Allergy to antibiotics: how it manifests itself, treatment,

Antibiotics are humanity's greatest discovery. They have saved and are saving the lives of thousands of people, but despite their beneficial qualities, antibiotic allergies are possible under certain circumstances.

There is a certain category of patients in whom a drug allergic reaction can develop suddenly, regardless of compliance with all the conditions for their admission.

The reasons for the development of the disease

A drug allergic reaction to antibiotics develops for various reasons. The most common are:

• the presence of concomitant pathological processes in the body (cytomegalovirus, mononucleosis, etc.);
• the presence of an allergic reaction to pollen, food, etc.
• genetic predisposition;

• an allergy to antibiotics can be caused by prolonged use of drugs;
• long-term drug therapy of any one medication.

In addition, an antibiotic allergy can appear when the patient's immune system is weakened. This is especially common in a child.

Manifestation of allergy to antibiotics

Allergic reactions to antibiotics largely depend on how long the medication is taken. As a rule, the first symptoms of allergy appear within 24 hours. There are also immediate reactions, when an allergy to antibiotics can develop several hours after the use of the drug.

Symptoms of antibiotic allergy are most often manifested:

• a hyperemic rash appears;
• quite often, rashes on the body resemble burns;
• swelling of tissue and excruciating itching;
• in severe cases, difficulty in breathing is possible;
• excruciating cough with wheezing;

• the patient is haunted by nausea, which turns into vomiting;
• having difficulty swallowing food.

The most dangerous symptoms are the development of anaphylactic shock and Quincke's edema. These conditions can be fatal if the situation is not stabilized in a timely manner.

Diagnostics

An allergy to antibiotics requires a diagnostic examination using special tests. First of all, the patient is interviewed for an allergic history, after which the doctor prescribes laboratory examinations to detect an allergic reaction to antibiotics:

1. Analysis of the skin. The medication patch is placed on the skin area. It is recommended to check for an allergic reaction to antibiotics no earlier than 2 days.

2. Allergy prick test. The final test appears after 15-20 minutes. If the papule is less than 3 mm, the result is considered negative and an intradermal test may be recommended.

3. Intradermal test. This test is recommended by administering an antibiotic (0.02 ml) intravenously. After some time, an allergic reaction appears (or is absent) on the skin, after which the doctor deciphers the result.

It is important to remember that virtually every antibiotic allergy skin test should be analyzed within 72 hours. Subsequently, it is necessary to treat the disease taking into account the diagnostics performed.

The course of the disease in childhood

Allergic reactions to antibiotics in children practically do not differ from the reaction of adults. The most common drugs that cause an acute allergic reaction are Ampicillin and Amoxicillin, especially if the doctor prescribes them to treat young children.

In addition, due to an immature immune system, an allergic reaction to antibiotics of the following series is possible:

• penicillins;
• tetracyclines;
• sulfonamides;
• chloramphenicol, nitrofurantoin;
• ciprofloxacin, vancomycin, etc.

In relation to infants, antibiotics are prescribed with extreme caution and only when treating a bacterial infection. It is not recommended to take medications if the baby just has a stomach ache or diarrhea begins. In this case, it is recommended for the baby to take the least toxic drugs in the form of solutions and suspensions, since children after taking antibiotics, various complications are possible and, first of all, disturbances in the work of the digestive systems.

In addition, in no case should self-treatment be carried out for infants, as well as older children. If a child is allergic to an antibiotic for the first time, you should see a doctor immediately to avoid complications.

Possible complications

Most often, drug allergies can appear suddenly and be accompanied by concomitant diseases. For example, with an allergic reaction to antibiotics in a child, an exacerbation of dermatoses and dermatitis is possible, psoriasis and acne appear.

In addition, the following complications are quite common:

• a hyperemic rash appears;
• there is a violation of cardiac activity in the form of arrhythmia;
• the development of Lyell's syndrome is possible, the onset of which is accompanied by slight redness, gradually increasing in size, after which watery blisters appear, subsequently bursting. The rash may resemble a post-burn condition, and such a manifestation should be treated without fail;
• drug allergy can provoke the development of Quincke's edema and anaphylaxis, especially in children. In this case, tachycardia, hyperemic skin rash and dyspnea are observed. This condition is considered extremely serious and requires immediate qualified assistance.

It is important to observe the dosage, since if it is violated, the patient may experience dizziness, vomiting and nausea. As a rule, immediate discontinuation of the drug is required.

Curative therapy

Treatment of negative symptoms is primarily aimed at getting rid of rash, itching, general intoxication etc. Drug therapy for antibiotic allergies involves the appointment of the following drugs groups:

• antihistamines (Suprastin, Zyrtec, Zodak, Loperamide, Suprastin, etc.) eliminate skin swelling, itching and neutralize skin rashes. Antihistamines are given as sprays, tablets, and injections;

• glucocorticosteroids (Elokom, Prednisolone, Dexamethasone, Locoid, etc.) are prescribed if the therapy is ineffective. As a rule, treatment involves the use of external hormonal agents, but in the absence of positive dynamics, it is recommended to do intramuscular and intravenous injections with hormonal drugs;

• in severe cases, treatment with Adrenaline is prescribed, which helps to remove the toxic effects on the body. The drug relaxes the muscular system, which is important if the patient has difficulty breathing. However, it should be remembered that it is not recommended to do injections with adrenaline for hypertension, as it increases blood pressure.

For the accelerated elimination of toxins from the body, it is recommended to use enterosorbents (Entorosgel, Polipefana, etc.). Allergy to an antibiotic in children, as in adults, proceeds in almost the same way. In this case, the treatment differs only in the selection of the required dosage. For a child, in the absence of aggravating circumstances, it is better to treat with external drugs.

Diet for antibiotic allergies

In case of allergic reactions to antibiotics, you must adhere to a special diet. This is necessary to restore the intestinal microflora and strengthen the immune system, especially when allergic reactions from antibiotics occur with frequent vomiting and diarrhea.

1. In the first few days, it is preferable to consume a large amount of liquid, after which some cereals and bread are added during the course.

1. In conclusion, fermented milk products are necessarily introduced.
2. At this time, it may be necessary to restore the mineral and vitamin complexes in case of allergy from antibiotics.
3. After 7 days, it is recommended to add boiled lean meat and low-fat fish, eggs, etc. to the diet.

It is important to remember that it is strictly forbidden to independently treat any diseases with the help of antibiotics, as this can disrupt the intestinal microflora and lead to serious consequences.
