Injectable progestins (DMPA, Depo-Provera) are a good contraceptive choice for women who:
a. Want menstrual regularity and predictability.
b. Have a history of thrombotic problems or breast cancer.
c. Have difficulty remembering to take oral contraceptives daily.
d. Are homeless or mobile and rarely receive health care.
ANS: C
Advantages of DMPA include a contraceptive effectiveness comparable to that of combined oral contraceptives with the requirement of only four injections a year. Disadvantages of injectable progestins are prolonged amenorrhea and uterine bleeding. Use of injectable progestin carries an increased risk of venous thrombosis and thromboembolism. To be effective, DMPA injections must be administered every 11 to 13 weeks. Access to health care is necessary to prevent pregnancy or potential complications.
