Description
Welcome to Humulin R U-500
Humulin R U-500 is an insulin that is used to control high blood sugar in adults and children with diabetes mellitus who need more than 200 units of insulin in a day.
Humulin R U-500 contains 5 times as much insulin in the same volume (500 units/mL) as Humulin R U-100 (100 units/mL).
It is not known if Humulin R U-500 is safe and effective when used in combination with other insulins or when used in an insulin pump.
Proven to lower A1C with the potential for fewer daily injections.1*
SELECT SAFETY INFORMATION
Humulin R U-500 is highly concentrated and contains 5 times as much insulin in 1 mL as standard U-100 (100 units/mL) insulin.
Do not share your Humulin R U-500 KwikPen or U-500 insulin syringes with other people, even if the needle has been changed. You may give other people a serious infection or get a serious infection from them.
Meaningful results, simpler regimen*†
In a clinical study, U-500 was shown to lower A1C by an average of 1.1% in people who were not well controlled when taking more than 200 units of standard U-100 insulin a day.‡
U-500 is an insulin that is taken 2 or 3 times per day. Because it can be prescribed without other insulins, you may be able to reduce the number of insulins you take.
*Compared to standard U-100 insulin. Most patients will require 2 to 3 daily injections of U-500. U-500 KwikPen dials and doses the units you need, up to 300 units at a time.
†With U-500, you can inject up to 80% less liquid and still get the dose you need.
‡The purpose of the study was to compare the efficacy and safety of 2 dosing treatments (2 or 3 injections per day) of U-500 in adults with type 2 diabetes who were uncontrolled with high doses of standard U-100 insulin. The results between the 2 treatments were similar.
24-week, open-label, randomized trial to compare the efficacy and safety of 2 dosing regimens (TID, n=162 vs BID, n=163) for U-500 insulin replacing high dose U-100 insulin (>200 units per day) with or without oral antihyperglycemic drugs in adult patients with uncontrolled type 2 diabetes. These regimens were found to be equivalent for A1C reduction over 24 weeks, and both were efficacious.1
Study conducted with U-100 insulin syringes and Humulin R U-500 vials.
SELECT SAFETY INFORMATION
- Do NOT perform dose conversion when using the Humulin R U-500 KwikPen or U-500 insulin syringe.
- Do not take Humulin R U-500 if your blood sugar is too low (hypoglycemia) or you are allergic to any of the ingredients in Humulin R U-500.
Humulin R U-500 is a concentrated insulin
U-500 is 5 times more concentrated than standard U-100 insulin. When insulin is concentrated, it takes less liquid per dose than standard U-100 insulin to help reduce your blood sugar levels.
With U-500, you can inject up to 80% less liquid and still get the dose you need. Reducing the amount of liquid may also reduce the number of times you have to inject in a day.* And because U-500 can be prescribed by itself, you may be able to reduce the number of insulins you take.
* Compared to U-100 insulin. Most patients will require 2 or 3 daily injections of U-500.
Here’s one way to think about it
Same number of units, 80% less liquid per dose.*
*Compared to standard U-100 insulin. Most patients will require 2 or 3 daily injections of U-500.
