When This Medicine Should Not Be Used
How to Use This Medicine
- IV: A nurse or other health professional may give you this medicine into a vein if you are in the hospital.
- Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
- You may be taught how to give your medicine at home. Make sure you understand all instructions before giving yourself an injection. Do not use more medicine or use it more often than your doctor tells you to.
- This insulin works faster than other types of insulin, and its effects do not last as long.
- 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.
- When you get a new supply of insulin, check the label to be sure it is the correct type. Do not change the brand unless your doctor tells you to.
- Use this medicine 15 minutes before a meal or right after you eat.
- Vial: Use only syringes that are made for insulin injections. Use a new syringe and needle each time you give yourself an injection.
- Cartridge or KwikPen: Use a new needle each time you give yourself an injection.
- Insulin pump:
- Keep the pump and pump equipment away from heat and direct light. Heat may increase the temperature of the insulin, and prevent it from working as it should.
- Make sure your pump is meant for fast-acting insulin.
- Use insulin lispro by itself. Do not mix it with other insulins.
- Change the insulin solution in the reservoir of the pump at least every 7 days. Change the infusion set and infusion site at least every 3 days.
- Tell your doctor right away if your insulin pump breaks or leaks. Your blood sugar levels may change rapidly. You may need to give yourself injections until your pump is fixed.
- Do not mix different types of insulin, unless your doctor tells you to. If you are told to mix lispro with a longer-acting insulin, draw up insulin lispro into the syringe first. Then draw up the longer-acting insulin and inject it right away.
- Do not transfer Humalog® U-200 from the KwikPen to a syringe for use.
