How soon is Depo-Provera effective? #859/6
How, or can, a person tell when hormonal contraceptives, like Depo-Provera has become fully effective?




A woman is protected immediately if she receives her first shot during the first 5 days of her period, if she is switching from an IUD to Depo or from pills, patches or rings to Depo, or if she is in the first 3 weeks postpartum.  Otherwise, use abstinence or a back-up method for 1 week.

 

            Here is a rule.  If in doubt, use a back-up contraceptive, using two contraceptives (usually condoms are the back-up method), never hurts.  Since no contraceptive is 100% effective, use a back-up when in doubt.

               

Key Words:  hormonal contraceptive, Depo-Provera, fully effective, back-up contraceptive, condoms
