When I did the Ovidrel injection before, I did it in my leg. At the time I did it over a year and a half ago, I did it in the top of my leg kind of perpendicular to my leg. Now, my RE has everyone doing the injections (regardless of whether it's Ovidrel, Lupron, Follistim, etc) on the side of the leg at a 90 degree angle to the leg which is still perpendicular, just on the side instead of the top. I think you can also do it in your abdomen...just depends on your personal preference. I actually started doing my Follistim injections in my abdomen and Lupron on the side of my leg. In my mind, I am putting the Follistim closer to where it needs to be (above my ovaries basically) so it just seems to make more sense to me, even though apparently there is not a difference between the upper thigh and the abdomen since they give you the option of doing it at either place.
As far as refrigeration, I do know that the Ovidrel is supposed to be refrigerated. I am not totally sure if it would affect the efficacy of the Ovidrel...I guess it depends on how long it has been out. There should be a little patient information leaflett that came along with it that should indicate the temperatures you can store it at. I would say if you have any doubt, call your doctor and check about it to be on the safe side. Good luck to you...hope everything goes well!
