When This Medicine Should Not Be Used

How to Use This Medicine

Injectable

  • Your healthcare provider will work with you to personalize your dose and treatment based on your insulin needs and lifestyle. You will be taught how to give yourself the injections. Make sure you understand all instructions. Ask the doctor, nurse, or pharmacist if you have questions.
  • Always double-check both the concentration (strength) of your insulin and your dose. Concentration and dose are not the same. The dose is how many units of insulin you will use. The concentration tells how many units of insulin are in each milliliter (mL), such as 100 units/mL (U-100), but this does not mean you will use 100 units at a time.
  • Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
  • You will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas.
  • Use a new needle and syringe each time you inject your medicine. If you use a syringe, use only the kind that is made for insulin injections. Some insulin must be given with a specific type of syringe or needle. Ask your pharmacist if you are not sure which one to use.
  • Check the label before use. Do not change the brand, type, or concentration unless your doctor tells you to. If you use a pump or other device, make sure the insulin is made for that device.
  • Gently shake or roll the vial or pen 10 times and then turn it upside down 10 times to mix the insulin.
  • Do not mix this insulin with any other insulin. Do not use the insulin if it looks clear.
  • Keep all medicine away from heat and direct light.
  • This medicine comes in different brands and forms. Follow the manufacturer's directions on how to store your specific insulin.
  • Throw away used needles in a hard, closed container that the needles cannot poke through. Keep this container away from children and pets.

Drugs and Foods to Avoid

Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.

  • Some medicines can change the amount of insulin you need to use and make it harder for you to control your diabetes. Tell your doctor about all other medicines that you are using.
  • Limit how much alcohol you drink.
