Itchy skin with red spots

If your skin is itchy and has red spots, this is probably due to allergic dermatitis. The impact of allergic dermatitis on the patient's skin health cannot be ignored. If this disease is not treated well, the long-term existence of this phenomenon will seriously affect the patient's mental state. Here are some treatments for allergic dermatitis!

1. Find the cause of allergies

Take a detailed medical history and carefully inquire about the environment related to the onset of the disease, the type, quantity, physical and chemical properties of the substances contacted, the length of contact time, the method of contact, whether there have been similar rashes in the past, etc. Analyze which substances may be related from the medical history to provide a basis for skin patch testing. Once the cause of the allergy is found, try to avoid further exposure.

Irritants or toxic substances remaining on the skin should be rinsed off as quickly as possible. Clean water, saline or light soapy water can be used for rinsing. If the contact object is a strong acid, it can be rinsed with a weak alkaline liquid (such as soda water); if it is a strong alkaline substance, it can be rinsed with a weak acidic liquid (such as boric acid solution).

2. Avoid stimulation

If clinical symptoms occur, local irritation should be minimized. Avoid scratching, do not wash with hot water, and avoid strong sunlight or hot air stimulation.

3. Systemic treatment

Oral antihistamines, such as cyproheptadine, diphenhydramine, chlorpheniramine, acrivastine, cetirizine, mizolastine, ebastine, desloratadine, etc.; large doses of vitamin C taken orally or intravenously; 10% calcium gluconate injection, intravenous push. If the area is extensive and the erosion and exudation are severe, glucocorticoids can be given. Such as oral prednisone, triamcinolone or dexamethasone; intramuscular injection of Diprosone. For severe cases, hydrocortisone or dexamethasone can be given intravenously first, and then maintained orally after the symptoms are alleviated.

If contact dermatitis is accompanied by local infection, such as lymphangitis, lymphadenitis, and soft tissue inflammation, antibiotics can be used. For mild cases, erythromycin, penicillin V potassium, cephalexin, or sulfonamides can be taken orally; for severe cases, penicillin, cephalosporin, or quinolone antibiotics can be given intravenously.
