# How Many Units Of Insulin In 1 Ml

Insulin dosed in mg? A set up for errors! In September, a new form of inhaled insulin, EXUBERA (insulin human [rDNA origin]) will become available. The drug has an onset of action similar to rapid-acting insulin analogs and must be inhaled about 10 minutes before a meal. It also has a duration of glucose-lowering activity comparable to subcutaneously administered regular human insulin. The drug will be available in 1 mg and 3 mg blisters of insulin powder, which are administered using the Exubera Inhaler. We have already received a report from a pharmacist who alerted us to the risk of serious medication errors with this high-alert drug. Exubera is dosed in mg (as during clinical trials), with a weight-based dosing chart for initial mg doses, and a conversion chart for equivalent doses in units (see table 1), the long-standing, usual way insulin is prescribed. Dose(mg) Approximate Regular Insulin SC Dose in IU Number of 1 mg EXUBERA Blisters per Dose Number of 3 mg EXUBERA Blisters per Dose 1 mg 3 1 - 2 mg 6 2 - 3 mg 8 - 1 4 mg 11 1 1 5 mg 14 2 1 6 mg 16 - 2 Table 1: Approximate Equivalent IU Dose of Regular Human Subcutaneous Insulin for EXUBERA Inhaled Insulin Doses Ranging from Continue reading >>

I need to administer 1 cc but the dropper is in .25 .5 and .75 mL.
How much is a "cc"? (and what is your base of knowledge - how do you know?)

1 cc = 1 mL
"cc" is an improper abbreviation for cm^3
"liter" is a special name for 1 dm^3 (SI Brochure). 1 dm^3 = 10 cm x 10 cm x 10 cm = 1000 cm^3.
But 1 L = 1000 mL (SI Brochure, milli- prefix definition)
Therefore 1000 mL must equal 1000 cm^3,
and 1 mL = 1 cm^3 = 1 cc, even if cc is incorrect.

Thats great 1 cc = 1 ml. However I have seen a syringe for diabetics that makes it more confusing. 1 ml = 40 units. Most diabetic syringes are (1 ml) 40 units. There are some that are marked 100 units (1ml) When comparing volumes in these syringes, 7 units from the 40 unit syringe when dispensed into a plastic container then drawn into the 100 unit syringe, fills to just a hair over the 16 unit mark. That I cannot explain. I just know it's true in this case. Maybe the syringes are mismarked. Maybe someone who knows more can explain it.
