how long does it take to get a shot of prednisone out of your system
Answer by rhistory (224). I have taken prednnisone in the past and can tell you that it will take a while for it to get out of your system. However, most doctors will tell you that it takes about 3-5 weeks for it to completely be out of your system.In addition, if you have a fast metabolism normaly the prednisone can leave faster.rednisone has some serious side effects like weight gain, water retention, night sweats, eye sight decrease ect. After you stop taking prednisone it may take up to a week to completely get out of your system but will take longer for some of the side effects to disappear.
