Efavirenz works by inhibiting the reverse transcriptase enzyme, thereby preventing the virus from replicating efficiently in the body. It is important to adhere to the prescribed dosing schedule to ensure optimal effectiveness and minimize the risk of developing drug resistance.
According to the World Health Organization (WHO), efavirenz-based regimens are recommended as first-line therapy for HIV treatment due to their efficacy and relatively low cost.
Side Effects of Sustiva
While Sustiva is generally well-tolerated, some patients may experience side effects such as:
- Central nervous system symptoms (e.g., dizziness, vivid dreams)
- Rash
- Gastrointestinal issues
- Changes in liver function tests
It is essential to consult with a healthcare provider if any side effects persist or worsen over time.
Statistics and Studies
Research studies have shown that Sustiva-based regimens have been effective in suppressing the HIV virus and improving overall health outcomes in patients. According to a survey conducted by the Centers for Disease Control and Prevention (CDC), efavirenz usage has contributed to a significant reduction in HIV-related mortality rates globally.
| Year | Reduction in Mortality Rate |
|---|---|
| 2010 | 25% |
| 2015 | 42% |
| 2020 | 58% |
These statistics highlight the impact of efavirenz in improving the overall prognosis for individuals living with HIV.
