How to Use This Medicine

Injectable

  • Your doctor will prescribe your exact dose and tell you how often it should be given. This medicine is given as a shot under your skin.
  • A doctor, nurse, or pharmacist will teach you how to give your insulin shots. Make sure you understand how to use the medicine before giving yourself a shot.
  • It is usually best to use this medicine about 15 minutes before eating. Talk with your doctor about your personal schedule, because your needs may be different.
  • Use a new needle each time you inject your medicine. You will be shown the body areas where this shot can be given (often your stomach area, thigh, or upper arm). 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.
  • Before using, mix the insulin by rolling the cartridge, FlexPen® syringe, or vial between your palms 10 times. Turn the cartridge or FlexPen® upside down at least 10 times, so the glass ball moves from one end to the other. You do not need to turn the vial upside down before using. The insulin should look cloudy or milky after mixing. Use your dose of insulin right away after mixing it.
  • Do not change the brand of your insulin unless your doctor tells you to. When you get a new supply of insulin, check the label to be sure it is the correct type of insulin.
  • Do not mix NovoLog® 70/30 or 50/50 with any other insulin.

If a dose is missed:

  • Call your doctor or pharmacist for instructions.
