  • Usage: Sustiva is primarily used as part of a combination therapy for HIV patients.
  • Mechanism of Action: Sustiva works by blocking the action of reverse transcriptase, an enzyme necessary for HIV replication.
  • Effectiveness: Clinical studies have shown that Sustiva, when combined with other antiretroviral agents, can significantly reduce viral load and increase CD4 cell counts in patients with HIV.
  • Side Effects: Common side effects of Sustiva may include dizziness, trouble sleeping, and rash. It is important to consult a healthcare provider if any adverse effects occur.

Key Points about Sustiva:

According to the Centers for Disease Control and Prevention (CDC), HIV treatment with antiretroviral therapy has led to a significant decline in HIV-related deaths in recent years.

Statistical data suggests that the cost of a month’s supply of Sustiva can range from approximately $1,000 to $2,000, depending on the dosage and location of purchase.
