Antiretroviral therapy usually is a combination of three or more types of medications that target the virus at different stages of its life cycle. Multiple angles of attack improve the chances of reducing the viral load.
How does HIV affect the body?
The virus enters the T-cell and replicates itself, destroying the host cell. As a result, the body slowly loses its ability to fight infections. A person contracts an HIV infection by contact with bodily fluids such as blood, semen, vaginal fluids, or breast milk from an infected person.

What is drug resistance in HIV?
What Is HIV Drug Resistance? Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself.

How It Works
- Antiretroviral drugs do not kill HIV. Rather, they prevent the virus from making copies of itself by blocking stages in the virus's life cycle (also known as the replication cycle). Antiretrovirals are so named because HIV is a type of virus known as a retrovirus.4 The different classes of antiretrovirals are named after the specific stage of the replication cycle they inhibit (block). The …
Side Effects
- While all drugs can cause side effects, current antiretrovirals tend to cause far fewer side effects than drugs of the past. Even so, side effects can occur and, in rare cases, be severe. Short-term side effects may include headache, fatigue, nausea, diarrhea, insomnia, and even a mild rash. These tend to resolve within a few weeks as your body adapts to treatment.4 Other side effects …
Tests
- Once you have been diagnosed with HIV, your doctor will advise to you start treatment immediately to bring the virus under control. You will not only be counseled on how to take your drugs correctly (including dietary restrictions) but also advised on ways to maintain optimal adherence. You will also be given baseline blood tests, called a CD4 count and viral load, again…
Other Treatments
- There are no other medications other than antiretrovirals that can control HIV. Even so, there are drugs a doctor may prescribe along with ART if you are at risk of an opportunistic infection. These preventive medications, referred to a prophylactics, are commonly prescribed when your CD4 count is below 200 or 100.18 These may include daily oral antibiotics to prevent severe infection…
Talk to Your Doctor
- The choice of ART relies heavily on the results of a genetic resistance testthat helps determine which antiretrovirals work best based on your virus's genetic profile. But it is not the sole factor involved in the selection of ART.17 As you will be the one taking the pills every day, you will want medications with the greatest tolerability and the greatest ease of use. Both help improve adher…
