Birth Control Shot
Combined Injectable Contraceptive (CIC) and
Progestin-only Injectable Contraceptive (PIC)
CICs are injections of the hormones estrogen and progestin that are administered once a month. PICs are injections of the hormone progestin that are administered once every two or three months (depending on the brand). Both injectable contraceptives work by suppressing ovulation, thickening the cervical mucus and changing the endometrium lining of the uterus.
Injectable contraceptives have an effectiveness of 99.9%, which is almost bulletproof. It is extremely unlikely for a woman to become pregnant while regularly following her injection plan.
A physician will administer the injections on the prescribed time-line for the given CIC or PIC.
