Just as skin rashes can be caused by a variety of factors, they can also be treated through a wide range of treatment options. The first step in treating a rash on the skin is to determine what caused its appearance. Determining the cause can be done at home, if the rash is something that has occurred before. However, it may require a trip to the doctor if it is a new rash that doesn’t look like any previous rashes, or if it isn’t responding to typical treatments that have worked in the past. Once the rash has been properly diagnosed, your doctor can let you know the appropriate treatment options available, as well as any necessary follow-up. Treatment options can include simply letting the rash run its course and clearing up on its own over a period of time, medicated creams or ointments that are available either over-the-counter or as prescribed by a doctor, and antibiotics in the case of a skin rash that is caused by a bacteria or viral infection.
