The Depo Provera (or Depo-Ralovera) is a contraceptive injection containing artificial progesterone, progestin. The injection goes into your buttocks or arm, and works for about three months. The shot starts working immediately if you have just finished your period, but after that you may have ovulated, so the egg may be in your system, and can therefore be fertilised. Your doctor will advise you regarding the timing of your shot.
The shot contains Depot Medroxyprogesterone Acetate (DMPA) which stops you from ovulating, and therefore prevents pregnancy – if there is no egg to be fertilised, no pregnancy can occur.
The Depo Provera is 99 per cent effective at preventing pregnancy, but does not offer protection against sexually transmitted infections.
About half of all women will stop getting periods entirely after one year of use. Your normal fertility should return three to four months after ceasing injections, but many women find it difficult to conceive after using the Depo Provera contraceptive shot, up past two years.
