Divided columns if recommendations differ: Initiation criteria (preexisting conditions) Continuation criteria (condition develops or worsens) Safety/Risk Categories 1 Method can be used without restriction 2 Advantages generally outweigh theoretical or proven risk 3 Method usually not recommended unless other, more appropriate methods are not available or not acceptable 4 Method not to be used 10 Contraceptive Methods in US Hormonal methods (prevent ovulation, alter endometrium and cervical mucous) Combined hormonal contraceptives Progestin only contraceptives Emergency contraceptive pills Progestin Intrauterine devices Implants Non hormonal methods Barrier contraceptive methods (condoms internal and external) Spermicides Fertility Awareness Based Methods Lactational Amenorrhea Method Coitus Interruptus Copper Intrauterine device Female and Male Sterilization 4

What about in the past? 9
