MTX preservative free

Well I recently had to get my prescription renewed and my Doctor says to get Preservative free which what was called in to the pharmacy. the question I have for you guys is since these vials I got are 25ml and I was told to use it only once and waste ( throw away the rest). Because its susceptible to Bacteria and other nasty things we don't need without a immune system.

problem is I've taken it before and I guess unknowingly rolled the dice. I also have some of the smaller vials of the preservative MTX. What do you guys do and think? i guess there is a scientific reason behind the Doctor requesting preservative free MTX.

I'm on the non-refrigerated MTX but it probably has preservatives. I get two doses from each vile. I'm supposed to wipe the tip of the vile with an alcohol swab before.

I'm not sure if you have a different version but it's best to follow the doctors orders and you can certainly bring it up.
 
Yes, I get Preservative free 25 ml vile. That's the only type my pharmacy supply. One use only, trash the rest. It does seems like a waste of medicine...

I always have left over after my 2 uses. Maybe it's just extra for ease of loading the syringe and in case any spurts out.

My vile is good for two uses. Each has 50mg and alcohol as a preservative.

I always find there is leftover so I think they may be putting a tad more in there.
