The goal of treating atopic dermatitis is to reduce inflammation, relieve itching, and prevent future flare-ups and complications. Accordingly, the drugs are often prescribed by the doctor in detail as follows:
Anti-itch cream: Apply to the skin with symptoms. However, if the patient's itching is so severe that it interferes with activities, sometimes an oral antihistamine is needed. With anti-allergic drugs that cause drowsiness, doctors often prescribe them to be taken at night.
Moisturizer: Combined with anti-itch cream to reduce discomfort. In addition to acute attacks, it is necessary to regularly moisturize the skin, soften the skin when the weather is cold and dry, and avoid letting the skin crack, which will easily cause itching.

Anti-inflammatory cream: Limiting the excessive local inflammatory reaction makes the symptoms better, the skin is less red, swollen, and itchy. However, the use of anti-inflammatory creams should be limited when the itching has subsided and other self-care therapies such as moisturizing and softening should also help control mild atopic dermatitis instead of medication. Because if used for a long time with anti-inflammatory, it will cause side effects such as discoloration of the skin, thinning of the skin, hair growth and easier skin infection. Anti-inflammatory creams with corticosteroids should only be used when prescribed by a doctor, depending on the nature of the lesion, the doctor will prescribe the active form from mild to severe.
Antibiotics: In case the patient has a skin infection, the treatment needs to add antibiotics for a short time to treat the infection. At the same time, if the wound is open and exudes fluid, the patient needs to cover with gauze, clean and change the bandage every day to avoid superinfection.
Limiting factors that trigger the onset of the disease: Many patients worry if atopic dermatitis is contagious because they are afraid that they have been infected by others or are afraid that they will spread it to their family members. However, the disease is caused by the body of each person, so it is completely non-contagious.
Accordingly, what needs to be done is to limit the factors that trigger the onset of the disease:
Avoid allergenic foods, clean the house, wash blankets, pillows, mattresses, carpets and curtains regularly, avoid smoke tobacco and dusty environment. Shower not too long; per shower, limit it to 15-20 minutes and use warm rather than hot water. Should use a perfume, soap fixed and mild detergent; If you want to make a change, you should test it on a thin area of skin first to see if it causes irritation. Limit scratching to a minimum; For young children, it is necessary to trim their nails and wear gloves at night. When it's hot, wear cool clothes. When it is cold and dry, it is necessary to nourish the skin with moisturizing creams and waxes. Drink enough water. Other treatment measures: Immunotherapy is gradually being applied in the treatment of atopic dermatitis in particular and diseases caused by other immune disorders in general. However, the long-term effectiveness and safety of these drugs are still unclear, so they are only approved for children over 2 years of age and for adults. Also, it should only be used when other treatments have failed or are completely intolerable.
Phototherapy: This method has also shown positive results, correcting disorders within and just below the skin structure; However, its wide applicability requires further study, as there is some evidence that it causes premature skin aging as well as an increased risk of skin cancer.
