<span>HIV medications can help lower your viral load, fight infections, and improve your quality of life. But even if you take them, you can still give HIV to others. They're not a cure for HIV.The goals for these medicines are to:<span>Control the growth of the virusImprove how well your immune system worksSlow or stop symptomsCause as few side effects as possible</span>The FDA has approved more than two dozen antiretroviral drugs to treat HIV infection. They're often broken into six groups because they work in different ways. Doctors recommend taking a combination or "cocktail" of at least two of them. This is called antiretroviral therapy, or ART.Your doctor will let you know specifically how you should take your medications. You need to follow the directions exactly, and you shouldn't miss even one dose. Or you could develop drug-resistant strains of HIV, and your medication may stop working.Some other medicines and supplements don't mix well with HIV drugs, so make sure you tell your doctor about everything you're taking.</span><span>Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)NRTIs force the HIV virus to use faulty versions of building blocks so infected cells can't make more HIV.<span><span>Abacavir, or ABC (Ziagen)</span><span>Didanosine, or ddl (Videx)</span><span>Emtricitabine, or FTC (Emtriva)</span><span>Lamivudine, or 3TC (Epivir)</span><span>Stavudine, or d4T (Zerit)</span><span>Tenofovir, or TDF (Viread)</span><span>Zidovudine, or AZT or ZDV (Retrovir)</span></span></span><span>Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)These are also called "non-nukes." NNRTIs bind to a specific protein so the HIV virus can't make copies of itself, similar to jamming a zipper.<span><span>Delavirdine (Rescriptor)</span><span>Efavirenz (Sustiva)</span><span>Etravirine (Intelence)</span><span>Nevirapine (Viramune)</span>Rilpivirine (Edurant)</span></span><span>Protease Inhibitors (PIs)These drugs block a protein that infected cells need to put together new copies of the HIV virus.

Answer:
UV radiation: Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. UV radiation is made up of three types of rays -- ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC).
