HIV reproduces at a rapid rate in the body, producing both perfect copies of itself and copies containing errors (mutations). Some of these viral mutations allow the HIV to resist the effects of a certain anti-HIV drug (called "drug resistance"), while remaining sensitive to other drugs used in a regimen. In some cases, one mutation will cause resistance to an entire class of HIV medications (called "cross resistance").
This is where HIV combination therapy, or HAART (Highly Active Antiretroviral Therapy), comes in. Using three or more anti-HIV drugs (antiretrovirals) from different classes in combination allows them to work together to keep HIV levels down. Doctors and scientists have found that HAART can help control HIV and in many cases the viral load can become so low that HIV may not be detected in the blood. This is called "undetectable viral load."
Because every patient is unique, you should talk to your healthcare provider to learn more about which HAART combination may work best for you.
Patients should read the Patient Information, including "What is the most important information I should know about Truvada?". It is important that you discuss your treatment options and any questions that you may have with your healthcare provider.
