3 A single dose of a fluoroquinolone can be used in areas of low prevalence of fluoroquinolone-resistant Neisseria gonorrhoeae. Because of resistance, fluoroquinolones should not be used if infection is acquired in Asia, the Pacific Islands (including Hawaii), California, and other areas with increased fluoroquinolone-resistant N gonorrhoeae. Quinolones should not be used in pregnant women.
4 The patient should have a negative pregnancy test result before emergency contraception is given. Although emergency contraception is most effective if taken within 72 hours of event, data suggest it is effective up to 120 hours.
