What are the clinical manifestations of drug induced dermatitis?

Drug-induced dermatitis often occurs when certain drugs are used. This is likely to lead to some localized itching, dermatitis, and even erythema, which should be carried out in time. First of all, you need to stop using the drug, and you can't use the drug that caused damage to ** again.

Dermatitis has always been a headache and worry for people, and people often find that they have a rash for unknown reasons. Drug factors are common, and this is an important predisposing factor for drug-induced dermatitis. People are still relatively new to this disease.

Next, let's get to know the symptoms of drug-induced dermatitis!

There are three main symptoms of drug-induced dermatitis.

1. Local symptoms.

The patient's ** will develop a drug eruption locally, which is symmetrical and widespread, and is brightly colored. It can occur anywhere on the body.

2. Systemic symptoms.

In addition to local symptoms, patients may also experience systemic symptoms such as headache, fever, nausea, and fatigue.

3. Other systemic symptoms.

This disease not only harms **, but also may cause damage to organs such as liver, kidneys, heart, joints, etc., and oral mucosal damage is also relatively serious.

Drug-induced dermatitis is mainly caused by improper medication** symptoms of redness, itching, and allergies. It can be distinguished according to the patient's past drug history, and related diseases of internal medicine and ** department can be excluded, such as scarlet fever and morbilliform drug eruptions should be distinguished from scarlet fever and measles, and bullous epidermal necrolytic drug eruptions should be distinguished from toxic epidermal necrosol.

Drug eruption, also known as drug-induced dermatitis, is a reaction to mucosal inflammation caused by drugs entering the human body through oral, topical and injection routes. The most common are sulfonamides, antipyretic analgesics, sleeping pills, penicillin, streptomycin, etc.

Drug-induced adverse reactions are very complex and can be roughly divided into: drug overdose, intolerance, idiopathic, ***, secondary effects and allergic reactions. Drug eruptions are the most common type of allergic reaction.

A key point in the diagnosis of drug-induced dermatitis.

1. Have a history of taking medication.

2. There is a certain risk period, the first dose of the drug is 5-20 days, and repeated use of the drug can cause the disease within 1-2 days or a few hours.

3. There are many types of rashes, and all types of drug eruptions have their own generation, regularity of development trend and separate clinical medical characteristics, but in addition to the main manifestations of atypia in fixed drug eruptions, drug eruptions have the characteristics of sudden onset, symmetrical rash, widespread whole body and bright colors.

4. Itchy white sensation, which can be accompanied by fever, headache, nausea, vomiting and fatigue and other systemic diseases. Critical illness is often accompanied by oral mucosal harm, and there will be liver, kidney, heart, bone joints and hematopoietic system hazards. The respiratory system can cause laryngeal edema, poor breathing, or anaphylactic shock to death.

5. The history of present illness is mostly subacute, and after stopping the use of sensitizing drugs, it can be triggered within about 1-3 weeks**, and then the drug can be attacked.

6. Laboratory examination, the total number of white blood cells can be increased, eosinophils can be increased, and there is leukopenia in some cases. Drug allergy test, ** allergy test is positive, drug provocation test and in vitro test are the basis for diagnosis.

The initial onset of drug-induced dermatitis has a risk period, which is generally at least 1 week, while the recurrence of the disease has no risk period and can occur immediately.

Second, drug-induced dermatitis generally occurs after several drug exposures, and rarely occurs in first-time contacts.

The above is a brief introduction to the characteristics of drug-induced dermatitis in Beijing Jingjing** Hospital, and more attention can be paid to drug-induced dermatitis in daily life. When there are similar symptoms of drug-induced dermatitis, it must be treated immediately to prevent the development trend of drug-induced dermatitis from being serious and causing harm to itself.
