What is this medicine used for?

  • This medicine is used to manage blood sugar in a patient who has diabetes mellitus (DM) (type 1 and sometimes, type 2).
  • For type 2 diabetes mellitus, insulin can be used alone or in combination with other diabetes medicine.
  • Pregnant women with diabetes caused by pregnancy, who are not controlled by diet alone, may require insulin.


How does it work?

  • Insulin is a hormone necessary for the body's use of food, especially sugar. Type 1 diabetics have no insulin of their own and require complete replacement. Type 2 diabetics still make insulin, but may require an outside source if their blood sugars are very elevated. Sometimes only short-term use of this medicine is needed for type 2 diabetes.


How is it best taken?

  • Take exactly as directed, by needle, into the fat stores of the skin. Talk to healthcare provider for complete education.
  • Follow diabetic diet recommended by healthcare provider.
  • Throw away needles in red box and return box to healthcare provider when full.
  • Start eating within 5 to 10 minutes after injecting NovoLog™ insulin.


What do I do if I miss a dose?

  • Talk with healthcare provider.


What are the precautions when taking this medicine?

  • Wear disease medical alert identification for diabetes.
  • Limit alcohol intake (includes wine, beer, and liquor). Can cause low blood sugar. This is most common if you miss a meal.
  • Keep hard candies, liquid glucose, or milk on hand for low blood sugars.
  • If you are 80 years of age or older, you may be more sensitive to low blood sugars (more confusion).
  • Do not drive if blood sugar has been low. There is a greater risk of an accident.
  • Increases in exercise can decrease insulin needs (be consistent).
  • Tell healthcare provider if you are allergic to any medicine. Make sure to tell about the allergy and how it affected you. This includes telling about rash; hives; itching; shortness of breath; wheezing; cough; swelling of face, lips, tongue, throat; or any other symptoms involved.
  • Tell healthcare provider if you are pregnant or plan on getting pregnant.
  • Tell healthcare provider if you are breast-feeding. Insulin dose may change.


What are the common side effects of this medicine?

  • Low blood sugar. This can cause anger, shaking, rapid heartbeats, confusion, sweating. Can be life-threatening if not treated with hard candies, liquid glucose, milk.
  • Nausea or vomiting. Small frequent meals, frequent mouth care, sucking hard candy, or chewing gum may help.
  • Weight gain (seen in type 2 diabetics).


What should I monitor?

  • Check blood sugar as ordered by healthcare provider. Call if glucose is less than 80 mg/dL or greater than 250 mg/dL. Bring results to follow-up visits.
  • Watch for low blood sugar. This can cause anger, shaking, rapid heartbeats, confusion, sweating.
  • Watch for high blood sugar. Causes many trips to the bathroom, thirst, and weight loss.
  • Check blood work. Talk with healthcare provider.
  • Follow diet plan and exercise program as recommended by healthcare provider.
  • Have an eye exam and visit to the foot doctor every year.
  • Check weight.


Reasons to call healthcare provider immediately

  • Signs of a life-threatening reaction. These include wheezing; tightness in the chest; fever; itching; bad cough; blue skin color; fits; swelling of face, lips, tongue, or throat.
  • Any signs or symptoms of infection. This may include a fever greater than 99 degrees, chills, sore throat, cough, increased sputum or change in color, painful urination, mouth sores, wound that will not heal, anal itching or pain.
  • Low blood sugar or very high blood sugar.
  • Any rash.


How should I store this medicine?

  • Check insulin's expiration date (on box and vial). If expired, do not use.
  • Unopened vials should be refrigerated. Do not freeze.
  • Opened vials can be stored at room temperature. Store away from direct light and extreme temperatures.
  • Opened vials should be thrown away after 1 month.


General statements

  • Do not share your medicine with others and do not take anyone else's medicine.
  • Keep all medicine out of the reach of children and pets.
  • Keep a list of all your medicines (prescription, herbal/supplements, vitamins, over-the-counter) with you. Give this list to healthcare provider (doctor, nurse, pharmacist, physician assistant).
