When This Medicine Should Not Be Used:
This medicine is not right for everyone. Do not use it if you had an allergic reaction to insulin degludec.
How to Use This Medicine:
- 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.
- 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 your doctor 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.
- If you use insulin once a day, it is best to use it at about the same time every day.
- Check the liquid inside the pen or vial. It should be clear and colorless. Do not use the medicine if it looks thick, cloudy, or discolored, or if it has particles in it. Do not mix this medicine with any other insulin or with water.
- 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. Do not use the exact same spot for each injection.
- Use a new needle and syringe each time you inject your medicine.
- Always check the label before use, to make sure you have the correct type of insulin. Do not change the brand, type, or concentration unless your doctor tells you to.
- Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
- Missed dose: Take a dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take your next dose at the regular time. Make sure that there are at least 8 hours between doses. Do not take extra medicine to make up for a missed dose.
- Unopened medicine: You may store the pen or vial in the refrigerator until its expiration date or at room temperature for up to 56 days. Protect from light. Do not freeze. Do not use the medicine if it has been frozen.
