Depo-Provera: The Birth Shot

Depo-Provera or commonly referred to as “the birth shot,” is a progestin only hormonal contraceptive injection. The mechanism of action of the hormone found in Depo-Provera prevents ovulation or the release of the egg from the ovaries of a woman. It also changes the cervical mucus, making it thick so it’ll be difficult for sperms to swim towards the mature egg thereby preventing fertilization. Also, it affects the endometrium by making it thin. This change prevents the implantation of the fertilized egg.

Depo-Provera provides protection for 12 weeks and is injected four times a year or every three months. If a woman is 2 or more weeks late in getting a birth shot, her health care provider may suggest a pregnancy test or may recommend emergency contraception if she had sexual intercourse in the previous 5 days. It provides protection immediately from the moment of the first injection.

Aside from being safe and convenient to use, the birth shot is one of the most effective contraceptive method available. It gives long lasting protection and may also prevent cancer of the uterine lining. It is highly recommended to women who are having a hard time remembering their birth control pill regimen. The shot is not contraindicated during breastfeeding although this may cause bleeding if given immediately after delivery. A window of 5 or more days is recommended before administration.

Like the birth control pill and patches, the birth shot also has side effects. These include irregular or heavier menstrual periods, headache, nausea and dizziness, breast pain and engorgement and weight gain. Depo-Provera may also cause you to lose your calcium stores and can put you at risk of osteoporosis.

Lastly, Depo-Provera cannot protect you from sexually transmitted diseases. Another form of contraception such as condoms should be used instead.
