PURPOSE and SAFETY SUMMARY

Important Facts About Humulin® (HUE-mu-lin) R U-500. It is also known as insulin human injection (500 units/mL).


Humulin R U-500 is a prescription insulin used in adults and children who need more than 200 units of insulin a day to control high blood sugar for their diabetes mellitus. It is more concentrated than standard insulin. It has 5 times as much insulin in each mL as standard insulin.


It is not known if Humulin R U-500 is safe and effective when used with other insulins, when used in an insulin pump, or in children. There were no studies done in children, so your doctor will give you special instructions for use in children.

WARNINGS

Humulin R U-500 may cause serious side effects, including:

  • Severe low blood sugar, which can lead to seizures, unconsciousness, and death.
  • Severe allergic reactions. Get medical help right away if you develop a rash over your whole body, have trouble breathing, have a fast heartbeat, or are sweating.
  • Swelling of your hands and feet. Tell your doctor if you are short of breath, have swelling in your ankles, or have gained weight suddenly.
  • Heart failure when taking a medication from a class of drugs called thiazolidinediones (TZDs) with Humulin R U-500. This may occur in some people even if they have not had heart problems before.
  • Low potassium in your blood (hypokalemia). This can lead to severe breathing problems, irregular heartbeat, and death.

Do not share your Humulin R U-500 KwikPen® or U-500 syringe with anyone. Even if you have changed the needle, you or the other person can get a serious infection.


When using the Humulin R U-500 KwikPen: The Humulin R U-500 KwikPen is made to dial and deliver the correct dose of Humulin R U-500 insulin. Do not remove Humulin R U-500 from the KwikPen to inject with any syringe. This could cause severe overdose and may lead to death.


When using the Humulin R U-500 vial: There is a special syringe to measure Humulin R U-500 called the “U-500 insulin syringe.” Only use the U-500 insulin syringe to inject Humulin R U-500.
