Treatment of acute urticaria, symptomatic treatment has good effect

The most important thing in treating urticaria is to understand the type and cause. Common ones are acute and chronic urticaria. The treatment of acute urticaria should be symptomatic according to the symptoms shown by the patient. Pay attention to your diet and avoid eating foods that are prone to allergies.

1. Symptomatic treatment of acute urticaria is effective quickly

1. For those with rash and itching as the main symptoms: oral antihistamine H1 receptor drugs, such as chlorpheniramine 4 mg to 8 mg or deschlorohydroxyzine 25 mg, 3 times a day. Patients with extensive rash and severe itching can be given chlorpheniramine 10 mg or diphenhydramine 20 mg at the same time, injected intramuscularly immediately or once a day.

2. For patients with severe illness and accompanied by laryngeal edema, asthma or hypotension: blood pressure changes should be observed and oxygen should be given. Subcutaneous or intramuscular injection of 0.1% epinephrine 0.3 ml~0.5 ml; intramuscular injection or intravenous small bottle of dexamethasone 5 mg; elderly people with cardiovascular disease should use it with caution. If laryngeal edema does not improve after the above treatment, tracheotomy and endotracheal intubation can be performed to assist breathing.

3. Patients with high fever, chills, joint pain, increased total white blood cell count and obvious left shift of the classified nuclei should first be given effective antibacterial drugs, and attention should be paid to finding the infection lesions and being alert to the occurrence of sepsis.

Types of acute urticaria

1. Acute eczema, which develops rapidly and the rash is polymorphic. The main manifestations are papules, papulovesicles, blisters, erosions, exudations, and crusts on the basis of erythema and edema. The boundaries of the lesions are unclear. In severe cases, it can spread throughout the body and cause severe itching.

2. Subacute eczema: after the acute inflammation is alleviated, the rash is mainly composed of small papules, scales and crusts, with only a small amount of papulovesicles, blisters and erosions; the skin lesions are relatively limited, and the itching is still severe.

3. Chronic eczema is caused by repeated attacks of acute eczema and subacute eczema. The symptoms include rough skin, scratches, crusting, soaking and hypertrophy, partial lichenification and pigmentation, and scattered papulovesicles on the periphery.

4. Scrotal eczema refers to a common skin disease limited to the scrotum. Its causes are complex and may be related to local uncleanliness, tight or non-breathable underwear (synthetic fiber products) or allergies, certain physical or chemical stimuli, and may also be related to mental factors.
