Use of combined oral contraceptives post abortion☆☆☆
Abstract
Background
Providing combined oral contraceptives (COCs) following surgical or medical induced abortion offers women an opportune moment to initiate a reliable contraceptive method.
Study Design
We conducted a systematic review, searching MEDLINE and The Cochrane Library for articles in any language concerning COC use following spontaneous, induced (medical or surgical) or septic abortion, from 1966 through June 2008. Seven articles were identified and evaluated using the United States Preventive Services Task Force system.
Results
Immediate COC initiation after first-trimester medical or surgical induced abortion did not increase side effects or prolong vaginal bleeding compared with use of a placebo, copper-bearing intrauterine device (IUD), nonhormonal contraceptive method or COC initiation at a later time. Initiating COCs after first-trimester surgical abortion produced small increases in coagulation parameters compared with IUD use; although they are statistically significant, their clinical relevance is unlikely. No study examined second-trimester induced or spontaneous abortion, or septic abortion.
Conclusions
Evidence shows that COCs can be safely initiated immediately following surgical and medical abortion in the first-trimester of pregnancy.
