Side Effects of Depo-Provera Before starting Depo-Provera, it is important to discuss potential side effects with your doctor. Bleeding Some people have irregular or prolonged bleeding while using Depo-Provera. Others will not have any problems with bleeding. Spotting and continuous bleeding are the main reasons people stop taking Depo-Provera. People who use Depo-Provera are more likely to stay on it if they are counseled about this potential side effect before receiving their first injection. There is no way to know ahead of time if you will experience irregular bleeding or spotting. The bleeding may continue until the progestin wears off. This can take up to 11 to 14 weeks after you stop getting the shot. Research suggests all bleeding stops for about 50% of people who use Depo-Provera continuously for one year. This includes regular monthly bleeding. With continued use, that number rises to 70%. Bone Density Loss Depo-Provera may cause bone mineral density loss. This leads to thinning bones and a high risk of bone fractures. Studies have shown that this may reverse when you stop getting Depo-Provera shots.
