Indications

Adiva in combination with other antiretroviral agents is indicated for the treatment of HIV-1 infection. This indication is based on analyses of plasma HIV- RNA levels and CD4 cell counts in controlled studies of up to 24 weeks in duration. At present, there are no results from controlled trials evaluating long term suppression of HIVRNA with Adiva.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) active against HIV-1. It blocks RNA and DNA dependent polymerase activities, including HIV-1 replication.

Pregnancy & Breastfeeding

Category D: There is positive evidence of human fetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).Lactation: Efavirenz may pass through breast milk and cause serious harm to the baby. It should not be used during lactation.
