A rash may occur after you contract HIV. It commonly appears on the face and chest but can also appear in other places. Medications used to treat HIV as well as certain infections may also cause rashes, including serious ones.
A rash is a symptom of acute HIV infection that usually occurs within the first 2 months after contracting the virus. Like other initial symptoms of HIV, it’s easy to mistake this rash for a symptom of another viral infection. Therefore, it’s important to learn how to identify and treat this rash.
According to UC San Diego Health, 90% of people living with HIV experience skin symptoms and changes at some stage of the disease.
The rash can develop because of conditions caused by HIV, or it can be a side effect of medications that treat HIV, called antiretroviral drugs (ART), or by other infections that may be more prevalent in patients with HIV.
Medication alert
Skin rashes associated with antiretroviral therapy are usually not serious and disappear within a few weeks. They’re often managed with symptomatic treatment to reduce any discomfort or itchiness. Sometimes, the antiretroviral medication may be changed to a different one.
The National Institutes of Health (NIH) reports that three main classes of antiretroviral drugs are responsible for causing skin rashes:
- non-nucleoside reverse transcriptase inhibitors (NNRTIs)
- nucleoside reverse transcriptase inhibitors (NRTIs)
- protease inhibitors (PIs)
NNRTIs like nevirapine (Viramune) are a common cause of medication skin rashes. Abacavir (Ziagen) is an NRTI drug that can cause skin rashes. PIs that are likely to cause rashes include tipranavir (Aptivus).
Whether caused by an HIV medication or by HIV itself, the rash typically appears as a red, flattened area on the skin that’s usually covered with small red bumps.
The rash may be itchy. It can appear on any part of the body, but it most often occurs on the face, chest, and sometimes on the feet and hands.
Range of severity
Some rashes associated with acute HIV infection or HIV medications are mild. Other rashes can cause serious damage to the skin, causing them to be life threatening.
One rare but potentially serious skin rash that can develop through the use of antiretroviral drugs is Stevens-Johnson syndrome (SJS). When this condition covers
- blisters on the skin and mucous membranes
- a rash that develops quickly
- fever
- swelling of the tongue
Your treatment plan for an HIV rash will depend on the cause of the rash. If you are HIV positive and experience a rash that isn’t relieved by over-the-counter drugs like hydrocortisone cream or diphenhydramine (Benadryl), see a healthcare professional who can determine the cause.
If your rash is a result of the infection itself, HIV medications can help your skin by restoring your immune system and reducing your viral load.
However, if the rash turns out to be caused by your current drug regimen, it may be treated by changing medications as determined by your doctor.
Lifestyle changes
In addition to medication, some lifestyle changes may help alleviate the symptoms of the mild form of this rash. Avoiding heat and direct sunlight can improve some rashes. Hot showers and baths can make the rash worse.
Sometimes, starting a new medication, trying a new soap, or eating a particular food may coincide with developing a rash. In this case, an allergy may be the cause. People living with HIV should contact their healthcare professionals if they notice a rash or are unsure about the cause.
Below are some of the most commonly asked questions about HIV rash.
How do I know if my rash is related to HIV?
The only definitive way to know whether your rash is related to HIV is to see a healthcare professional. A doctor or dermatologist can evaluate the rash, order testing, and confirm a diagnosis. If you’re concerned about your risk of HIV infection, it’s important to talk with a healthcare professional for guidance.
