This review article aims to determine the effectiveness and safety of repeated precoital and postcoital use of levonorgestrel for pregnancy prevention. The data suggested that pericoital oral levonorgestrel is safe and moderately effective. However, the quality of the studies was suboptimal. A pressing need exists for rigorous research to evaluate pericoital use of levonorgestrel as a primary means of contraception.
