how long does it take to work aranesp
The active ingredient of Aranesp is darbepoetin alfa that works in exactly the same way as the natural hormone erythropoietin. It will take your body a short time to make red blood cells, so it will be about 4 weeks before you notice any effect. If you are on dialysis, your normal dialysis routine will not affect the ability of Aranesp to treat your anaemia. Your doctor may have prescribed Aranesp for another reason.
