HCG and NOT bacteriostatic water

[mank]

Hello.
I write from Italy.
Here in pharmacy we have 2 hcg brand (Pregnyl and Gonasi) that have not bacteriostatic water: have only "water for injection, sodium 0.9" without preservative "benzyl alchool".
Personally i use the Gonasi Hp 1000 or 2000 ui, that have 1 ml of "water for injection".
Bacteriostatic water for injection (with benzyl alchool) is not avalilable in pharmacy.
I could only purchase it on line from UK o USA.
Any one know how much time maximum is adviced keep the vial with the mixed compund in the fridge ?
I tryed not more then 4 days without any problem, i don't know if trying more days.
Thank you a lot.

Hi Mank, Sodium, likely as the chloride in solution, is a preservative. Check the package insert or refer to the manufacturer's web site for allowable storage after reconstitution. I'm speculating that Italy has not approved benzyl alcohol.
