Immunology & HIV Practice Test

Maintaining a consistent medication schedule for HIV patients is crucial primarily to avoid the development of drug-resistant HIV. When antiretroviral therapy (ART) is not taken as prescribed, this can lead to suboptimal drug levels in the bloodstream. In such cases, the virus may not be fully suppressed, allowing it to replicate. This replication can lead to mutations, which may result in strains of the virus that are resistant to the medications being used.

Drug resistance can significantly complicate treatment, making it difficult to manage the infection effectively. Once the virus develops resistance to certain medications, those drugs may no longer be effective, potentially leading to treatment failure. This necessitates the use of alternative, often more complex, regimens, which may have different side effect profiles and may not be as effective due to limited options. Thus, adhering to a strict medication schedule plays a critical role in controlling the virus, ensuring effective treatment, and preventing the long-term complications associated with drug-resistant HIV.
