Review Meta Analysis
Safety of efavirenz in the first trimester of pregnancy: an updated systematic review and meta-analysis.
Evidence of the risk of birth defects with efavirenz use is limited. We updated a meta-analysis of birth defects in infants with first trimester efavirenz exposure up to July 2011. ⋯ The relative risk of defects comparing women on efavirenz-based (1290 live births) and nonefavirenz-based regimens (8122 live births) was 0.85 (95% CI 0.61-1.20). One neural tube defect was observed (myelomeningocele), giving an incidence of 0.07% (95% CI 0.002-0.39).
