Resistance

While Sustiva is effective in controlling viral replication, continuous use of the drug can lead to the development of resistance mutations. This underscores the importance of regular monitoring and adherence to treatment plans to ensure long-term effectiveness of the medication.

Adverse Reactions

Cost and Accessibility

Sustiva, like other antiretroviral medications, can be expensive. In the United States, the average retail price of a 30-day supply of Sustiva 600 mg is around $1,200. Access to affordable HIV treatment is crucial for individuals worldwide, and efforts are being made to increase availability and affordability of these life-saving medications.
