Face allergies often itchy red treatment includes general treatment and drug treatment. 1. General treatment: the main thing is to look for allergens that cause allergies, such as allergies to some objects or food allergies, avoid contact and avoid eating, and to keep the skin of the face clean, do not scratch excessively with your hands, do not eat stimulating food, and do not smoke. 2. Medication: As facial allergies can cause obvious itching, they can be treated with topical medications such as glycerite lotion and tacrolimus ointment to improve the discomfort, or with antihistamines, such as loratadine and cetirizine. When using medication, patients must follow the doctor’s instructions to use reasonable medication, because improper use of medication may aggravate the skin damage.
