The Prophylactic Effect of Doxycycline on Postoperative Infection Rate After First‐Trimester Abortion
A prospect i ve double-blind study was performed to evaluate the effect of  prophylactic antibiotic treatment before induced abortion . Eight hundred consecutive women admitted for first-trimester abortion , without signs of genital infection or antibiotic use in the last three weeks , were included in the study . Doxycycline 400 mg or placebo was given as a single oral dose ten to 12 hours before vacuum aspiration .  Ninety-one women ( 11.8 % ) returned to the hospital with suspected complications . Thirty-two of these women were diagnosed as having pelvic inflammatory disease , eight of whom ( 2.1 % ) had received doxycycline before the abortion and 24 of whom ( 6.2 % ) had received placebo , a statistically significant difference ( P < .01 ) . A history of pelvic inflammatory disease increased the risk of developing it again after an abortion
