Contraceptive injections are available as a type of hormonal contraceptive for women. Commonly known as Depo, Depo-Ralovera and Depo-Provera, contraceptive injections are considered as a long-acting option for hormonal control. The injections have artificial progesterone called Depot Medroxyprogesterone Acetate (DMPA). A single contraceptive injection is effective for 12 to 14 weeks.
Contraceptive or progesterone injections are administered either in the gluteus muscle, thigh muscle or the arm. They are normally given during the menstrual cycle in the first five days. The injections can only be administered by a health professional. The injection itself stops the ovaries from the process of ovulation. It also helps increase the thickness of cervical wall so that male discharge cannot enter the uterus during intercourse.
Once a contraceptive injection has been administered into the body, it releases the hormone into the bloodstream over an interval of 12 to 14 weeks. This protects the woman against pregnancy for a period of three months.
There are many advantages of the contraceptive injection which include, but are not limited to, the following:
While there are many advantages of contraceptive injections, there are also many disadvantages. These include the following:

If you want to get another continue the injection, you should follow up with your doctor/healthcare professional in the tenth week, approximately two weeks before the effect wears off.
If you are planning to get a contraceptive injection after the first days of your menstrual cycle, you should keep in mind that it will take seven days before it becomes fully effective. During the week after you get the injection, you will either have to abstain from sex or use other forms of contraceptive in order to avoid an accidental pregnancy.

Progesterone injections can cause a long delay in resuming periods after you stop the treatment. If you wish to become pregnant within a year of stopping after this form of contraception, you should look at other methods that can be reversed easier than progesterone injection.
The injection itself is very effective. The effectiveness of this form of contraception ranges from 94% to 99%.
