I recently purchased a sterile vial of ketamine to inject, but I noticed it doesn't have a preservative---just ketamine and water. If I puncture the rubber top to take out one dose, is the whole vial contaminated or can I store it and take another dose in a few days or weeks? I can't imagine any bacteria could get in if I disinfect the top with alcohol, insert a sterile syringe, and remove it quickly. If that's the case though, why would multi-use vials use preservatives? For years I've been injecting powder ketamine (dissolved in boiled tap water) and I've never had a problem, but could reusing a single-use vial be more dangerous because bacteria grow better in water? Would refrigerating or freezing (if I leave room for the water to expand) the vial help? Could I add a little benzyl alcohol and then reuse it?
