Skin rashes are usually treated with topical ointments, creams and lotions to address itching, explains WebMD. Treatment may also include oral antibiotics, antihistamines, laser therapy, liquid nitrogen, steroid injections and ultraviolet light, depending a patient's specific skin condition. Some rashes do not require any type of treatment.
People who suffer with eczema often experience intense itching and can develop flaky patches of red skin in response to several environmental and lifestyle factors that elicit an allergic response in the body. Hydrocortisone creams are often successfully used to calm the inflammation that accompanies atopic eczema outbreaks, notes WebMD.
In some cases, doctors may elect to administer steroid injections at the site of a rash. This is true of various types of outbreaks, such as lichen planus, atopic eczema and granuloma annulare. Light therapy is often reserved for more aggressive cases that do not respond to any of the aforementioned treatments, explains WebMD.
Mild cases of granuloma annulare and pityriasis are commonly monitored without the need for treatment, unless symptoms progress enough to cause a patient considerable discomfort or cosmetic embarrassment. Patients are advised to visit a doctor for a possible skin biopsy to identify the exact cause of a rash and determine the best course of treatment, according to WebMD.
