Ointment skin allergies are usually caused by contact dermatitis due to allergies to the body caused by the medication and rubber components of the ointment. Contact dermatitis is an inflammatory reaction of the skin at the contact site or even outside the skin caused by contact with some external allergens or irritants. Topical ingredients in plasters, rubber-like ingredients, etc. can lead to localized contact dermatitis. If the plaster appeared skin allergy, the first thing is not to paste the plaster again. You can take oral medication with topical medication under the professional guidance of a physician, such as oral cetirizine hydrochloride tablets or azelastine hydrochloride tablets, and then apply topical dianabed cream. You can also choose fluticasone propionate cream and other glucocorticoid hormone drugs, which can effectively inhibit multiple lesion patterns triggered by allergy, and can make clinical symptoms such as erythema, papules, vesicles and exudation subside rapidly, so as to achieve the therapeutic effect. The treatment cycle is about 1-2 weeks. In addition, pay attention to keep the local skin clean and dry, avoid scratching, avoid hot water scalding, avoid the use of alkaline soap and so on. Ointment skin allergy medication should be carried out under the professional guidance of a physician, and should not be used indiscriminately.
