BAC Water. How long is it good for after using it?

[Nextlevel]

I've had the same water for about 2 months now and I've used it to fill up 3 vials. I am wondering how long can I use the water for after putting a syringe in to fill up vials? I am currently storing the water in the fridge. The reason i bring this up is this is the first time I experienced redness around where I injected.

Thanks

I use hospira bac water and I use it until it is empty which for me is about two and a half months..I personally would not go over three months after opened but everyone has different risk tolerance

i usually just add a little more benzyl alcohol after a few months of use. Never had an issue
