I was wondering what size needle everybody uses with Soluf-Cortef. My doctor really never told me or prescribed them. I think it was an oversight because she prescribed the Soluf-Cortef. My cousin is a pharmasict and gace me 23 gauge needles. I need to take injections once a week for MS and I use 23 gauge. I am thinking they may be too big for her. I picked up a few from my sister of 25 gauge needles (She has MS also and takes diffferent meds). I have an appointment next month with the endo and will ask her then, but would appreciate your input. She is nine years old and weighs 72 pounds. Thanks again, Michele
