What medication can be used for red, itchy bumps on the body?

Normally, red bumps on the body that are itchy may be caused by dry skin, clothing friction, eczema, contact dermatitis, urticaria, and other reasons. It is recommended to seek medical attention promptly and use medications such as desonide cream, hydrocortisone butyrate cream, loratadine tablets, chlorpheniramine and paracetamol tablets, and cetirizine tablets under the guidance of a physician. Detailed analysis is as follows:

1. Dry Skin

In dry environments or due to frequent bathing and the use of harsh cleansing products, skin moisture loss accelerates, weakening the skin barrier function. External irritants can more easily penetrate the skin, possibly causing red bumps and itching. Medication is generally not required for treatment. It is recommended to reduce the frequency of bathing and use mild, moisturizing bathing products.

2. Clothing Friction

Wearing rough-textured or tight-fitting clothing can cause frequent friction against the skin, damaging the skin's stratum corneum, increasing skin sensitivity, and altering local blood circulation, leading to red bumps and itching. Medication is generally not required for treatment. One should choose soft, loose, and breathable cotton clothing, avoid wearing irritating fabrics such as synthetic fibers or wool, change and wash clothes frequently, and keep clothing clean.

3. Eczema

Eczema is associated with hereditary factors, abnormal immune function, environmental factors, and more. The immune system may mount an excessive immune response to internal and external factors, leading to skin inflammation and impaired skin barrier function, causing red bumps accompanied by severe itching. Blisters, erosion, and other symptoms may also appear. Patients can use medications such as desonide cream, hydrocortisone butyrate cream, and calamine lotion under the guidance of a physician.

4. Contact Dermatitis

Contact of the skin with allergens or irritants, such as cosmetics, metal accessories, chemical substances, etc., can cause inflammatory reactions on the skin. Under the stimulation of inflammation, the aforementioned symptoms may occur. It may also be accompanied by symptoms such as fever and chills. Patients can use medications such as triamcinolone acetonide acetate cream, chlorpheniramine and paracetamol tablets, and hydrocortisone tablets according to medical advice.

5. Urticaria (Hives)

Urticaria can be caused by drug allergies, infections, physical factors, and others. Allergic reactions in the body may lead to the dilation of small blood vessels in the skin and increased permeability, causing raised, red, hive-like bumps with intense itching. It may also be accompanied by symptoms such as abdominal pain and diarrhea. Patients can use medications such as cetirizine tablets, loratadine tablets, and dexamethasone tablets as advised by a physician.

In daily life, one should avoid contact with known allergens and irritants, such as certain plants and chemical detergents. At the same time, maintain a clean and hygienic living environment, regularly clean the rooms, and reduce the breeding of allergens such as dust mites.
