Best Answer: the longest you should use an open vial of insulin for is 30 days but you will have a 20 day supply per vial if you are using U-100 insulin. 1 cc equals 100 units so a 10 ml bottle contains 1000 units, at 48 units per day that will last you 20 days. not equivalent syringes. use only insulin syringe and read type/ strength of insulin. Too dangerous to discuss on yahoo. not equivalent to TB syringes either.
If the dosage is 50u of NPH and 10u of rugular... shoot 50units of air into nph vial and withdrawl syringe. inject 10 units of air into regular vial and draw back 10u of regular insulin, withdrawl syringe, try not to get bubbles.Place syringe back into NPH and draw back to the 60 unit mark. If you go PAST 60 units...never inject mixed insulin back into NPH vial.nject 10 units of air into regular vial and draw back 10u of regular insulin, withdrawl syringe, try not to get bubbles. place syringe back into nph and draw back to the 60 unit mark. if you go past 60 units...never inject mixed insulin back into nph vial.
