If you have not already been tested for HIV, your doctor should perform a blood test to check if you have the virus. If you are negative, your doctor will then determine if your rash is from an allergic reaction to food or other factors. You may also have a skin issue like eczema.  If you are HIV positive, your doctor will likely prescribe anti-HIV medication and treatment.  If you are already on anti-HIV medication and the rash is mild, your doctor will tell you to continue taking the medication as the rash should go away after one to two weeks. To reduce the rash, especially the itching, your doctor may prescribe an antihistamine, such as Benadryl or Atarax, or a corticosteroid-based cream. Your severe rash may also appear along with other symptoms of the virus, such as fever, nausea or vomiting, muscle pain, and mouth sores. If you haven’t already been tested for the HIV, your doctor should perform a blood test to check if you have HIV. Based on the results of your blood test, your doctor will then prescribe anti-HIV medication and treatment. You may develop hypersensitivity to certain medications and your HIV symptoms, including your HIV rash, may get worse. Your doctor should advise you to stop taking the medication and provide alternative medications you can take. The hypersensitivity symptoms usually disappear in 24-48 hours. There are three main classes of anti-HIV drugs that can cause skin rashes:  NNRTIs NRTIs PIs NNRTIs, such as nevirapine (Viramune) are the most common cause of medication skin rashes. Abacavir (Ziagen) is an NRTI drug that can cause skin rashes. PIs like amprenavir (Agenerase) and tipranavir (Aptivus) can also cause rashes. If your doctor advises you to stop a certain medicine due to hypersensitivity or an allergic reaction, do not take it again. By taking it again, you run the risk of causing an even more severe reaction that could progress and make your condition much worse. People with HIV have an increased incidence of bacterial infection due to abnormalities in immune cell function. Staphylococcus aureus (MRSA) is prevalent among those who are HIV-positive, which may lead to impetigo, inflamed hair follicles, boils, cellulitis, abscesses, and ulcerations. If you have HIV, you may want your doctor to test for MRSA.
