Continuation rates among injectable contraceptive users

Few published data exist on the ongoing use of depot medroxyprogesterone acetate, the injectable contraceptive. Women who obtained the injectable from Planned Parenthood of the Rocky Mountains between January 1993 and March 1995 were followed to ascertain continuation rates for the method. Of the 5,178 women who received an initial injection, only 57% returned for a second administration; 63% of those who returned for their second injection went on to receive a third. The overall one-year continuation rate was 23%. No significant differences in continuation rates were found based on age, race or payment type.
