Can insect bite dermatitis heal itself?

After dermatitis occurs, the patient will feel severe itching on his skin. At this time, the best way is to conduct a systemic examination and treatment. Nowadays, more and more people are suffering from insect bite dermatitis, which is a complication that occurs after being bitten by mosquitoes. Then the patient can only use some antibiotics and other drugs for treatment, which will be more effective.

Western medicine treatment

(1) Systemic treatment

① Antihistamines mainly have a calming and antipruritic effect. The commonly used dosage is 4 mg of chlorpheniramine, 3 times a day. It is best to continue using it for a few days after the child's skin lesions have subsided.

② Antibiotics should be given appropriately for cases with extensive skin lesions, erosion, and exudation, even if there are no obvious signs of bacterial infection. Such as erythromycin 250 mg, 4 times a day.

③ In principle, steroid hormones are not used in general cases, but atopic asthma is an exception. For severe cases, it can be used for a short period of time (2 to 3 weeks) to control symptoms as quickly as possible.

④Immunosuppressants include azathioprine, cyclosporine A (CYA) and interferon. There is not enough data to prove its efficacy in treating AD.

(2) Local treatment

① Steroid hormones are used for skin lesions with severe inflammation but no obvious erosion or exudation. During the treatment, change the types appropriately. Use strong ones at first to control the symptoms as quickly as possible, and then gradually switch to medium and low-efficiency ones after a few days. For skin lesions in different parts of the body, attention should also be paid to the selection of varieties. If the skin lesions are extensive, especially in infants and young children, it is advisable to use preparations with weaker effects or lower concentrations.

②Antibiotics are used for infected skin lesions. Often used in combination with steroid hormones.

③ Tars such as coal tar and bran oil are effective against AD. Pastes are commonly used and applied alone or in combination with hormone preparations.

Traditional Chinese Medicine Treatment

⑴Treatment based on syndrome differentiation

① Fetal heat syndrome

In infancy, the rash often occurs on the cheeks with erythema, densely packed needle-tip-sized papules, papulovesicles, blisters and exudates. When the exudate dries up, an orange-yellow scab forms, which is then peeled off to reveal a flushed erosive surface. The tongue is red, with little coating and purple fingerprints.

The treatment method is to clear the heart, guide the redness, protect the yin and stop itching.

② Damp-heat syndrome

In the childhood stage, the most common rashes are pinhead papules, papulovesicles and small blisters, some of which are fused into patches with mild infiltration and are mostly concentrated in the elbows, popliteal fossa and other parts. The patient feels severe itching, and scratching causes bleeding or exudation. The tongue is red, the tongue coating is thin yellow, and the pulse is moist and rapid.
