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.
Insulin Syringes. An insulin syringe has three parts: a needle, a barrel, and a plunger. The needle is short and thin and covered with a fine layer of silicone to allow it to pass through the skin easily and lessen pain. A cap covers and protects the needle before it is used. The barrel is the long, thin chamber that holds the insulin.
