Why are antiretrovirals used?
Antiretroviral therapy (ART) combines several medicines to help treat HIV. They reduce the amount of virus in your body (viral load). This helps keep your immune system healthy and helps you live longer. The medicines also help prevent HIV from becoming AIDS.
How do they work?
When you combine these medicines, HIV slows down. The virus is slower to make copies of itself (multiply) in the body. This allows your immune system to stay healthy.
What about side effects?
Some people feel sick to their stomach when they take these medicines. They may have belly pain or vomit. Some people have diarrhea. They may also feel tired or dizzy.
