Pharmacist Tips

  • Write down the date when you start (opened and used) your Lantus vial. Your Lantus vial should be stored in the refrigerator. If unopened and unused, your Lantus vial can be stored until its expiration date. If you have opened and used your Lantus vial, dispose of it after 28 days even if there is insulin left.
  • Do not use your insulin if it is cloudy or has been frozen.
  • Signs and symptoms of hypoglycemia can include: sweating, hunger, dizziness/lightheadedness, blurred vision, fast heart beat, shakiness, trouble concentrating/confusion, slurred speech, anxiety, irritability, or mood changes. 
  • If your blood sugar < 70 mg/dL, that is hypoglycemia. Follow the “Rule of 15” if this occurs: 
    • Consume 15 grams of carbohydrates, which is about 1⁄2 cup of juice or a tablespoon of sugar, honey, or corn syrup. 
    • Then, wait 15 minutes and re-check your blood sugar. If it is still  < 70 mg/dL, repeat the step again. 
    • If the second check is > 70 mg/dL, consume a small portion of protein afterwards.
  • Be sure to check your blood sugar daily and document the readings.
