What Is Insulin
WHAT YOU NEED TO KNOW:
Insulin is a hormone made by the pancreas. Insulin helps your body use sugar for energy. It removes sugar from your blood and helps lower your blood sugar levels. You may need to take insulin if your pancreas is not making enough. You may also need to take insulin if your body cannot use insulin correctly.
Contact your healthcare provider if:
- You have questions or concerns about your condition or care.
Use insulin safely and check your blood sugar levels:
- Prepare and give insulin as directed. Make sure you prepare and use your insulin correctly. Give yourself insulin based on your blood sugar level and directions from your healthcare provider. Ask him if you have questions.
- Check your blood sugar level at least 3 times each day. Some types of insulin can cause your blood sugar level to decrease quickly. Ask your healthcare provider when to check your blood sugar levels during the day. Check it any time you have symptoms of high or low blood sugar levels.
- Know what your blood sugar levels should be. If you check your blood sugar level before a meal , it should be between 80 and 130 mg/dL. If you check your blood sugar level 1 to 2 hours after a meal , it should be less than 180 mg/dL. Ask your healthcare provider if these are good goals for you.
- Write down your blood sugar level results. Bring the results to your follow-up appointments. Your healthcare provider may use the results to make changes to your insulin type or dose, eating plan, or exercise plan.
- Ask your healthcare provider how to manage your diabetes during sick days. You may need different amounts of insulin during illness. You may also need different amounts during stress, travel, or when you change your diet or activity.
How to store insulin:
Follow the storage directions on the label or package insert that came with the insulin. Do not use your insulin if there are clumps or color changes. Cloudy insulin that has small, white, particles that will not mix should be thrown away. Clear insulin that looks cloudy should be thrown away.
- Always check the expiration date on your insulin bottle. Do not use insulin beyond its expiration date.
- Do not store insulin in the freezer, direct sunlight, or the glove compartment of a car. Throw away insulin that has been frozen or exposed to very warm temperatures (above 85° F).
- You can store opened or unopened insulin in the refrigerator or at room temperature. If you store your insulin at room temperature, keep it in a cool, dry place.
- If you travel, keep the insulin in a cool pack. This will help make sure the temperature of the insulin stays below 86° F (30° C). Do not leave insulin in direct sunlight.
