Help with needles!

[Bossman]

Putting a needle through a soft rubber stopper doesn't dull it in any significance. And as long as you clean the top of the vial with a sterile swab of rubbing alcohol or Iodine then you don't have to worry about contaminating it either.

I've never switched needles. The years I've worked in hospitals I've never seen a Doctor or nurse do this either.

Personal preference though, couldn't hurt. But in my opinion, doesn't help either

Even though I switch mine up, I wonder why I have never seen a nurse/doctor switch them up for one of my injections? Is it really needed?
