Treatment for facial redness caused by drug allergy

For the treatment of facial redness caused by drug allergies, the first step is to immediately discontinue the allergenic medication and increase fluid intake or administer intravenous fluids to promote drug metabolism and accelerate its elimination from the body. For patients with mild symptoms, oral antihistamines such as loratadine or cetirizine can be used for anti-allergic therapy. If the condition is severe, corticosteroids or human gamma globulin injection may be required to rapidly control symptoms. Additionally, mild to moderate potency topical corticosteroid creams, such as hydrocortisone cream, can be applied to the affected areas to reduce inflammation and redness. During treatment, it is important to maintain facial cleanliness, avoid using irritating cosmetics or cleansers, and take proper sun protection measures to prevent further damage to the skin barrier. Moreover, patients should maintain a light diet and avoid spicy, cold, or other foods that may exacerbate allergic symptoms.
