Sustiva Dosage and Administration

If you have been prescribed Sustiva as part of your HIV treatment, it is essential to follow the dosage and administration instructions provided by your healthcare provider. Proper dosing is crucial for the effectiveness of the medication and to minimize the risk of side effects.

The recommended dosage of Sustiva for adults and adolescents weighing at least 40 kg is 600 mg once daily. It is typically taken on an empty stomach, preferably at bedtime to reduce the risk of central nervous system side effects such as dizziness and impaired concentration.

Missed Dose:

If you miss a dose of Sustiva, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double dose to make up for a missed dose as it can increase the risk of side effects.

The Efficacy of Sustiva

Sustiva has been shown to be highly effective in the treatment of HIV infection. Clinical trials have demonstrated its ability to reduce viral loads and increase CD4 cell counts in patients. According to a study published in the New England Journal of Medicine, Sustiva, when used in combination with other antiretroviral drugs, resulted in a 76% reduction in viral loads after 24 weeks of treatment.

In another trial conducted by the World Health Organization (WHO), Sustiva was found to be significantly more effective than other NNRTIs in reducing the risk of virologic failure in patients with HIV. The study reported a 92% virologic response rate among patients receiving Sustiva compared to 82% with other NNRTIs.

Furthermore, a meta-analysis of multiple clinical trials concluded that Sustiva-based regimens were associated with a lower risk of treatment failure and virologic rebound compared to other antiretroviral therapies.

Overall, the data suggests that Sustiva is a highly effective and reliable option for the treatment of HIV infection, with strong evidence supporting its efficacy in reducing viral loads and improving immune function.
