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.
U100= 100 units of insulin per milliliter of fluid in the vial. So 1 unit = one hundredth of a milliliter. One unit of insulin is one unit no mater which kind, each insulin strength has. has it's own syringe. One Unit of U100 has the same amount of active ingredient. as one unit of U40 or U60.
