Injectable contraceptive is an effective method of contraception that can be injected subcutaneously or in the muscles (usually buttock or upper arm). It prevents pregnancy from taking place by releasing progestogen in the body. Each dose of injectable contraceptive prevents pregnancy for three months. Currently intramuscular variety of Injectable contraceptive is available at government facilities, free of cost.
It is a safe method for maintaining spacing between pregnancies. It can also be used by breastfeeding women (after 6 weeks of delivery) as it does not affect the quantity, quality and composition of breast milk. It reduces blood loss during periods, decreases menstrual cramps and also reduces pre-menstrual tension.
Injectables do not lead to infertility. After discontinuation of injectable contraceptive, a woman can become pregnant.. Pregnancy usually occurs 7-10 months from last dose of injection.
Every month a woman’s body prepares for conception. The inner lining of uterus becomes thick and soft as it gets more blood supply. If she does not conceive that month, this inner lining of blood is expelled as menstrual blood flow. With injectables, the monthly preparation for pregnancy in a woman’s body does not occur. There is no release of ovum or thickening of inner lining of uterus. The menstrual cycle gradually comes to a halt after irregular bleeding for some time. When a woman stops using Injectable contraceptive, the body starts preparing for conception and menstrual bleeding is resumed.
