Which of the following is a principle of drug therapy for HIV infection?

• A. Clients with chronic HIV do not require treatment if they are asymptomatic.
• B. Pediatric treatment is limited due to fewer antiretrovirals that are safe for children.
• C. It is preferable to begin treatment with single-drug therapy
• D. Treatment regimens should be individualized depending on CD4 counts.

Answer: (C)

Beginning HIV drug therapy with a single agent reflects a cautious, phased approach to treatment. Starting with one antiretroviral can quickly begin reducing viral replication while allowing the clinician to closely monitor how the patient tolerates the medication, any adverse effects, and potential drug interactions. This initial step provides a safe window to assess response before adding additional antiretrovirals, aiming to build a robust, multi-drug regimen that minimizes the chance of resistance. Decisions about when and what to add next are guided by the patient’s CD4 counts, viral load, overall health, and ability to adhere to a complex schedule. While current guidelines often favor potent combination regimens from the outset, the principle behind starting with a single drug highlights the importance of careful initiation, monitoring, and individualized planning in HIV therapy.
