Depo-Provera contains a hormone which is similar to the hormone progesterone that is produced by the body. It is used to prevent women from becoming pregnant. Depo-Provera is a long-term contraceptive and is given as an injection once every 12 weeks. Depo-Provera is only used as a short-term method of contraception in certain circumstances. These circumstances include those women who are awaiting sterilisation, have just had a rubella vaccine or women whose partners are waiting to find out if their vasectomy has been successful.
Depo-Provera is usually given during the first five days of a menstrual period, or for contraception within five days of your baby's birth if you are not breast feeding. If given at any other time, then you may need to take extra contraceptive precautions until it starts to work. Ask your prescriber or family planning nurse or read the patient information leaflet that comes with your medicine for more information.
Further injections are usually given at intervals of 12 weeks and within 89 days of the previous injection to prevent the need for further contraceptive measures. If given at any other time, then you may need to take extra contraceptive precautions until Depo-Provera starts to work. Ask your prescriber or family planning nurse or read the patient information leaflet that comes with your medicine for more information.
You and your prescriber or family planning nurse should carefully weigh the risks and benefits of having this form of contraception. It is important you understand that the effects of Depo-Provera last for 12 weeks and it is impossible to immediately reverse the effects of the medicine once you have been given an injection.
Once the effect of the injection has worn off, it may take time for fertility to return. This means it may take a while before you can conceive. The time it takes for women to become pregnant when they stop having Depo-Provera varies in different women. For more information ask your prescriber or family planning nurse or read the patient information leaflet that comes with your medicine.
Depo-Provera helps provide contraception but it may also increase the chances of getting breast cancer. Depo-Provera also causes bone loss as it reduces levels of oestrogens in the body. Oestrogens help prevent bone loss and slow down the development of osteoporosis. Depo-Provera is not suitable as a contraceptive in children and adolescents or for women who want to use it for long periods of time. If you are at risk of having osteoporosis or bone fractures, it is important you discuss with your doctor if there are any other forms of contraception you could use instead of Depo-Provera.
