What if a woman is late for her Depo-Provera injection?
Each 150 mg injection provides reliable contraception for 13 weeks (90 days). If the injection is delayed 1 week it is advisable to first determine if the woman has been sexually active in the last week. If the woman has not had sexual intercourse a negative pregnancy test should be obtained and the Depo-Provera should be given. If the woman has been sexually active she should be instructed to use an alternative birth control for two weeks. After the two week interval a negative pregnancy test should be obtained and the Depo-Provera should be given as prescribed. There is no need to wait for a woman’s next menstrual cycle to give the repeat injection.
