Caption:

INDICATION AND SAFETY SUMMARY

Humulin® (HUE-mu-lin) R U-500 (500 units/mL) is for adults and children who need more than 200 units of insulin in a day to control high blood sugar for their diabetes mellitus. It is more concentrated than Humulin R U-100. It has 5 times as much insulin in each mL as Humulin R U-100 (100 units/mL).

It is not known if Humulin R U-500 is safe and effective when used with other insulins or when used in an insulin pump.

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. If you do not use the right syringe, you may take the wrong dose of Humulin R U-500. This could cause severe overdose and may lead to death.

Do NOT perform dose conversion when using the Humulin R U-500 KwikPen or U-500 insulin syringe.

Do not use Humulin R U-500 in an insulin pump or inject it into your vein.

Do not take this medicine if you have low blood sugar.

Do not change the insulin you use without talking to your doctor. Changing insulin may lead to low or high blood sugar.

Do not drive or use heavy machinery until you know how Humulin R U-500 affects you. Do not drink alcohol while using Humulin R U-500.

Common side effects

The most common side effects of Humulin R U-500 include:

Low blood sugar (hypoglycemia). Talk to your doctor about low blood sugar symptoms and treatment. Symptoms may be different for each person.

Allergic reactions, such as redness and swelling at the site where you inject.

Skin thickening or pits at the injection site (lipodystrophy).

Itching and rash.

These are not all the possible side effects of Humulin R U-500.

Tell your doctor if you have any side effects. You can report side effects at 1-800-FDA-1088 or www.fda.gov/medwatch.

Before using

Tell your doctor if you are pregnant or plan to become pregnant. Also tell your doctor about:

Any allergies you have. Your doctor can check if the medicine has ingredients that may cause a reaction.

Any medical conditions, including problems with your liver, kidney, or heart.

All the medicines you take, especially a class of drugs called thiazolidinediones, or TZDs. Be sure to include the over-the-counter medicines, vitamins, and herbal supplements you take.

How to take

Read the instructions that come with your Humulin R U-500 carefully. Take it exactly the way your doctor tells you.

Know how much Humulin R U-500 you are supposed to take. Do not change your dose unless your doctor tells you to.

Check the label of your insulin each time you use it. This will help you make sure you are using the right one.

Test your blood sugar before you take Humulin R U-500. Do not take it if your blood sugar is too low.

Do not mix Humulin R U-500 with any other insulin.

Always use a new needle when injecting Humulin R U-500. This will help you avoid infection.

Inject Humulin R U-500 under your skin. Change (rotate) where you inject your insulin with each dose. Do not inject your insulin into the exact same spot. Avoid injecting your insulin into areas where the skin has pits or lumps, or is thickened, tender, bruised, scaly, hard, scarred, or damaged. This will help reduce your chance of getting pits, lumps, or thickened skin where you inject your insulin.

About the U-500 KwikPen®

You may notice that the U-500 KwikPen has some similarities and differences from what you’re used to:

  • Same size as other KwikPens
  • It dials and doses in 5-unit increments (standard U-100 pens dial and dose in single-unit increments)*
  • It holds 1500 units per pen (standard U-100 pens only hold 300 units)
  • You'll receive 2 pens per pack
  • Distinctive aqua color

*Please see the Instructions for Use included with your pen.

You’ll need to use a pen needle with your U-500 KwikPen. Your doctor may prescribe BD needles, which are recommended for use with your KwikPen. Pens and pen needles are for single-patient use only and should not be shared, even in healthcare facilities, as infection or disease can be spread from one person to another. Do not withdraw insulin from the pen using any syringe. You may need a separate prescription for your pen needles.

What to expect

To know if U-500 is helping to improve your glucose, check your blood sugar.

Low blood sugar is the most common side effect of U-500.

It’s normal to want to understand possible side effects like low blood sugar when starting a new insulin. Be sure to talk to your doctor about the causes and how to identify and manage low blood sugar.

Take your dose 30 minutes before eating a meal as your doctor instructed.

Timing is important to help reduce the risk of low blood sugar (hypoglycemia).

As with any insulin, there is potential to experience low blood sugar at any time, including in the first few weeks as you’re getting used to your new medication or dose. Checking your blood sugar as directed by your doctor will help monitor for any highs or lows, as well as possible improvements in your blood sugar.

What are the potential side effects of Humulin R U-500?

Side effects of Humulin R U-500 may include low blood sugar that is severe and that can last a long time. Symptoms of low blood sugar may happen suddenly and may include:

  • sweating
  • dizziness
  • drowsiness
  • headache
  • or other symptoms

Severe low blood sugar can cause you to:

  • become confused
  • pass out (become unconscious)
  • have seizures or coma
  • and could cause death

Talk with your doctor about how to tell if you have low blood sugar and what to do if this happens while taking Humulin R U-500. Follow your doctor's instructions for treating your low blood sugar. Tell your doctor if low blood sugar from insulin use is a problem for you. Your doctor may need to change the amount of Humulin R U-500 that you take, or change your meal plans or your exercise program to help you avoid low blood sugar.

Experiencing side effects of insulin use?

If you are experiencing any side effects of taking insulin, please contact your doctor. Get emergency medical help if you have:

  • severe low blood sugar
  • trouble breathing

SAFETY SUMMARY

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. If you do not use the right syringe, you may take the wrong dose of Humulin R U-500. This could cause severe overdose and may lead to death.

Do NOT perform dose conversion when using the Humulin R U-500 KwikPen or U-500 insulin syringe.

Do not use Humulin R U-500 in an insulin pump or inject it into your vein.

Do not take this medicine if you have low blood sugar.

Do not change the insulin you use without talking to your doctor. Changing insulin may lead to low or high blood sugar.

Do not drive or use heavy machinery until you know how Humulin R U-500 affects you. Do not drink alcohol while using Humulin R U-500.

Common side effects

The most common side effects of Humulin R U-500 include:

  • Low blood sugar (hypoglycemia). Talk to your doctor about low blood sugar symptoms and treatment. Symptoms may be different for each person.
  • Allergic reactions, such as redness and swelling at the site where you inject.
  • Skin thickening or pits at the injection site (lipodystrophy).
  • Itching and rash.

These are not all the possible side effects of Humulin R U-500.

Before using

Tell your doctor if you are pregnant or plan to become pregnant. Also tell your doctor about:

  • Any allergies you have. Your doctor can check if the medicine has ingredients that may cause a reaction.
  • Any medical conditions, including problems with your liver, kidney, or heart.
  • All the medicines you take, especially a class of drugs called thiazolidinediones, or TZDs. Be sure to include the over-the-counter medicines, vitamins, and herbal supplements you take.

How to take

  • Read the instructions that come with your Humulin R U-500 carefully. Take it exactly the way your doctor tells you.
  • Know how much Humulin R U-500 you are supposed to take. Do not change your dose unless your doctor tells you to.
  • Check the label of your insulin each time you use it. This will help you make sure you are using the right one.
  • Test your blood sugar before you take Humulin R U-500. Do not take it if your blood sugar is too low.
  • Do not mix Humulin R U-500 with any other insulin.
  • Always use a new needle when injecting Humulin R U-500. This will help you avoid infection.
  • Inject Humulin R U-500 under your skin. Change (rotate) where you inject your insulin with each dose. Do not inject your insulin into the exact same spot. Avoid injecting your insulin into areas where the skin has pits or lumps, or is thickened, tender, bruised, scaly, hard, scarred, or damaged. This will help reduce your chance of getting pits, lumps, or thickened skin where you inject your insulin.
