What is Depo-Provera?
Depo-Provera is an injection containing the synthetic hormone progestin which is called depo-medroxyprogesterone acetate (DMPA). Depo-Provera is a hormonal method of contraception obtained by prescription.
How does Depo-Provera work?
Depo-Provera works through the synthetic hormone (DMPA) which helps regulate a woman’s ovaries similar to the way the natural hormone progesterone works.
Depo-Provera prevents pregnancy in one of three ways:
- First, it prevents the ovaries from releasing an egg, which is also known as ovulation.
- Second, it thickens the cervical mucus which acts as a barrier preventing the sperm from reaching the egg.
- Third, it changes the lining of the uterus preventing implantation. Ethical Consideration
How do you use Depo-Provera?
Depo-Provera is a prescription and the injection is obtained from your healthcare provider every 11 to 13 weeks. The healthcare provider will inject the synthetic hormone in the upper arm or in the buttocks. The initial injection is given within the first five days of your menstrual bleeding. Follow up injections are repeated every 11 to 13 weeks.
How effective is Depo-Provera?
Depo-Provera has a failure rate of less than 1% when it is used correctly and consistently. When used correctly only 3 in 1,000 women will get pregnant. You should take a pregnancy test if you are experiencing any pregnancy symptoms.
What are the side effects or health risks of Depo-Provera?
Irregular bleeding is the most common side effect. For some there may be increased light spotting and breakthrough bleeding, whereas others may experience longer and heavier bleeding. For most women, after a year of use periods usually become fewer and lighter or may stop altogether.
Depo-Provera has side effects similar to those experienced by users of oral or other hormonal types of contraception which include:
- Breast tenderness
- Moderate weight gain
- Change of appetite
Other reported side effects include: acne, anxiety, backaches, bloating, depression, leg cramps, hair loss or excessive hair growth, or loss of sex drive. You should not use the injections if you think you are pregnant; consult your physician about using Depo-Provera while breastfeeding.

Yes. However it may take several months before your cycle returns to normal.

Pregnancy is possible when you stop using the birth control injections, but it may be delayed.
