what size needle for b12 injection Is It Okay To Use A With Insulin Syringes? Dr. prescribed B12 injections. Pharmacy

hi I find it very easy to reach either arm but admit people do ask me that,I cant see why it would be a problem I just sit on end of bed with stuff all laid out on a clean towel and sharps bin handy,draw up b12 with a red filter needle,personal preference here,then discard and do the injecting with the orange needle , if the b12 is cold or you do have a bead of it on injecting needle then yes your right it can sting but again that is a rarity for me

Here is what we screen for

This depends on multiple factors, as everybody is unique and reacts differently to supplemental injections

Thank you once again for all your helpful information
