Corticosteroid ointments, such as dexamethasone acetate or betamethasone valerate, are remedies for topical use, that is, use on the skin, indicated in cases of dermatitis, eczema, itching, redness or skin allergies, for example. This is because corticosteroids have a potent anti-inflammatory action, controlling skin inflammation by mimicking the corticosteroid hormones that are naturally produced by the body by the adrenal glands.
In addition, corticosteroid ointments also decrease the immune system response, reduce cell renewal and decrease blood vessel dilation, and therefore, can be used in cases of allergy or skin redness. Know how to identify the signs of skin allergy.
It is important to emphasize that corticosteroid ointments may have different indications depending on the type of corticosteroid present in their composition and, therefore, should only be used with medical indication. In addition, the use of corticosteroid ointment for children should only be done with pediatrician guidance.
