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 antiretrovi…
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, agains…
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…
Summary
- Antiretroviral therapy is used to control HIV. It relies on drugs that inhibit points of the viral replication cycle so the virus cannot make copies of itself and infect immune system cells. Antiretroviral drugs are usually given daily in the form of a pill, which may contain a combination of drugs. These medications may have side effects. The drugs used in antiretroviral therapy are …
