However, the experienced side\u2010effects and acceptability may vary between different groups or societies.<jats:italic>Objective.<\/jats:italic>The primary objective of this study was to determine side\u2010effects and acceptability of two emergency contraceptive pill (ECP) regimens among users in Kampala, Uganda.<jats:italic>Study design.<\/jats:italic>Randomized clinical trial.<jats:italic>Methods.<\/jats:italic>A total of 337 women were enrolled in a double blind randomized clinical trial. Women requesting ECPs within 72 hours after unprotected sexual intercourse received either LNG or the Yuzpe regimen. The women returned for follow\u2010up after three days and a follow\u2010up interview was performed after one year.<jats:italic>Results.<\/jats:italic>Levonorgestrel had significantly fewer side\u2010effects than the Yuzpe regimen (<jats:italic>p<\/jats:italic>&lt; 0.001). There was a significant association between having worries about the method and experiencing side\u2010effects (<jats:italic>p<\/jats:italic>&lt; 0.001). Most women (81%) were prime users of EC. The majority would recommend ECP to other clients.<jats:italic>Conclusions.<\/jats:italic>Levonorgestrel is a superior option to the Yuzpe regimen and should be promoted as the recommended ECP. Having worries about ECP may influence experience of the side\u2010effects. Correct information is critical in promotion of ECP use.<\/jats:p>","DOI":"10.3109\/00016341003611220","type":"journal-article","created":{"date-parts":[[2010,4,28]],"date-time":"2010-04-28T06:42:34Z","timestamp":1272436954000},"page":"670-676","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A
