i usually do 3-5 injections per needle
When I was poor and out of work I used to use one syringe twice a day for a week, therefore a box of syringes lasted 2 years. I use one a day now twice per day. I do not use DMI methods so inject just twice a day.
I use all pens now but i do use a clean needle one each one for each injection. I had a reaction to one insulin and i was not sure if it was the reuse of a needle or the insulin so i changed sites and found a reaction to the insulin after this scare i decided to be more careful and not take the chance.
@ $14/100 why reuse?
When I have to split dose, I fill the syringe and inject 1/2 in one spot and the other 1/2 in another within seconds of each other. Then pitch the syringe. One infection and it can cost you a lot more than the money you saved trying to be frugal.
Also, when using an insulin pen, if you leave the needle cap on the pen, it can leak.

Waste, I guess. I don't like that part of this disease, so I rabidly re-use.
This is an ancient thread, but like JaninaWalker who answered here back in mid-2011, I reuse my 3/10s and 5/10s for as long as possible -- until the numbers have rubbed off the outside of the syringe, or until the point hurts. I'm averaging about 20 days per needle these days. I don't clean the syringe with alcohol as that leaves an alcohol residue in the syringe that I do not want to inject subcutaneously.
Never had a site infection. Ever. And I have been doing this a while (a long while). A few uncomfortable injections, sure, but I've had those even with a brand new needle when I happen to catch a nerve, so that doesn't really put me off.
Good for you! The infection thing I know is propaganda to sell more of them. I was very low income for several years and used one, twice a day, for 7 days and never had a problem. I have more money these days so use them only twice. I used to sharpen my 26 gauge steel needles with Emory cloth once a week so a dull modern needle means nothing to me now. We have it made in the shade!!! I also use the stabber for my meter for a year before replacing because then I always get guaranteed blood.
When I was on the pen (during the first few months of my diagnosis) I did not realize I was supposed to change them and was using them up to 4 or 5 times...then I met a guy in university and his dad is an endo, he FREAKED when he found I used them more than once - then a few years after that, I switched to syringes (my life changed for the better after that, the pen and I are not friends!) and I use one per injection (which is usually 4-6 syringes a day).
