Uncomfortable skin rashes can arise from simple contact irritation or from allergic reactions to foreign substances. Both irritant contact dermatitis and allergic contact dermatitis require home care to relieve the pain of itchy, red rashes and to prevent infection of the damaged skin. Patients may develop one-time or chronic skin symptoms, depending on their level of exposure and type of sensitivity. While home treatments are similar for any kind of skin irritation, knowing how the skin was harmed will aid recovery and prevent future health problems.
Cleansing
In the case of known contact with corrosives or toxic plants such as poison ivy, patients should wash the affected area as soon as possible. The University of Maryland, or UM, Medical Center points out that an immediate flushing with soap and water may prevent skin irritation in some cases.
Removing any remaining allergenic substances from the skin surface will prevent patients from cross-contaminating other parts of the body. Poison ivy resins, for example, can remain lodged under a patient's fingernails for days and cause more problems when scratching or rubbing the eyes.
Itch Medication
Severe itching accompanies some skin rashes, including those generated by poison ivy and food allergies. Over-the-counter oral antihistamine medicines such as diphenhydramine control the inflammation and itching of skin irritation.
Home treatment may also include topical anti-inflammatory or anti-itch ointments, such as hydrocortisone cream or calamine lotion. The Mayo Clinic notes that in severe cases, doctors may prescribe stronger antihistamines or oral corticosteroids.
Topical Compresses
Inflammation leaves the surface of skin rashes warm, red and swollen. Covering the area with clean, cool, moistened bandages or soft cloths, as the UM Medical Center suggests, will alleviate surface inflammation and pain. It will also curb the urge to scratch, preventing infection.
Soothing Baths
Skin conditions that aren't limited to a small area may respond to hydrotherapy home treatments. The Mayo Clinic recommends taking periodic soothing anti-inflammatory baths. Patients can purchase hypoallergenic, therapeutic bath products or make their own by adding a handful of baking soda or finely ground oatmeal to a tub of cool or lukewarm water. Soaking relieves skin irritation symptoms and prevents scratching.
Allowing Self-Healing
Sometimes doing too much for a skin rash delays rather than encourages recovery. According to the UM Medical Center, some conditions simply need to be left alone.
Patients who use too much hydrocortisone cream or too many home treatments may see their symptoms worsen. If itching is extreme or the skin blisters and breaks, medical care may be necessary. But if patients cease treatment and the skin improves, they might continue to allow the condition to heal on its own.
