Generic Sustiva (Efavirenz)
Efavirenz is the active ingredient in Sustiva® (Stocrin® in some regions), an NNRTI used with other antiretrovirals to treat HIV-1. Generic efavirenz contains the same active ingredient at the same strengths and is produced by licensed pharmaceutical manufacturers, typically far below the originator price. Used as prescribed by a licensed medical professional.
What is Sustiva (Efavirenz)?
Sustiva® is the originator brand for efavirenz, developed by Bristol Myers Squibb. It is prescribed, in combination with other antiretroviral medicines, for the treatment of HIV-1 infection. It is a prescription-only medicine used under medical supervision.
How Efavirenz works
Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It interferes with the reverse-transcriptase enzyme HIV uses to copy itself, helping to reduce the amount of virus in the body. It is always used as part of a combination regimen directed by your doctor.
Sustiva vs generic Efavirenz
Generic efavirenz contains the identical active ingredient at the same strengths as branded Sustiva, produced by licensed pharmaceutical manufacturers. Widely available generics have made HIV treatment far more affordable worldwide. Use and monitoring are guided by your doctor.

Who Efavirenz is prescribed for
Efavirenz is prescribed for adults and children living with HIV-1, as part of combination antiretroviral therapy determined by an HIV specialist.
Dosage & administration
Efavirenz is usually taken once daily, often at bedtime and on an empty stomach, as part of a combination regimen. Taking it at bedtime can reduce daytime dizziness or drowsiness, and avoiding high-fat meals limits side effects. Consistent daily dosing is important for it to work and to reduce resistance.
Dosage must be determined by a qualified healthcare provider. Do not change your dose or stop treatment without medical advice, and always follow the patient information leaflet supplied with your medicine.
Possible side effects
Reported side effects of efavirenz may include dizziness, vivid dreams or sleep disturbance, rash, and mood changes, which often ease over the first weeks. Tell your doctor about any persistent mood changes, and if you are or may become pregnant. This is not a complete list.
This is not a complete list. Read the patient information leaflet for full details and report any concerning or persistent symptoms to your healthcare provider promptly.
