Since use of two NNRTIs proved not beneficial in terms of efficacy and safety, co-administration of efavirenz and another NNRTI is not recommended.
Kuna kahe NNRTI kasutamine ei ole efektiivsuse ja ohutuse osas kasulikuks osutunud, ei ole soovitatav efavirensi manustamine koos mõne teise NNRTI- ga.
