Important Safety Information for Lantus® (insulin glargine [rDNA origin] injection)

Do not take Lantus® if you are allergic to insulin or any of the inactive ingredients in Lantus®.

You must test your blood sugar levels while using insulin, such as Lantus®. Do not make any changes to your dose or type of insulin without talking to your healthcare provider. Any change of insulin should be made cautiously and only under medical supervision.

Do NOT dilute or mix Lantus® with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Lantus® must only be used if the solution is clear and colorless with no particles visible. Do not share needles, insulin pens or syringes with others.

Tell your doctor about other medicines, especially ones commonly called TZDs (thiazolidinediones), and supplements you are taking because they can change the way insulin works. Before starting Lantus®, tell your doctor about all your medical conditions including if you have heart failure or other heart problems, liver or kidney problems, are pregnant or planning to become pregnant, or are breast-feeding or planning to breast-feed. If you have heart failure, it may get worse while you take TZDs with Lantus®.

The most common side effect of insulin, including Lantus®, is low blood sugar (hypoglycemia), which may be serious. Some people may experience symptoms such as shaking, sweating, fast heartbeat, and blurred vision. Severe hypoglycemia may be serious and life threatening. It may cause harm to your heart or brain. Other possible side effects may include swelling, weight gain, injection site reactions, including changes in fat tissue at the injection site, and allergic reactions, including itching and rash. In rare cases, some allergic reactions may be life threatening.

Hyperglycemia and Hypoglycemia

What to Do When Your Blood Sugar Levels Rise Too High or Fall Too Low

Even if you're very careful about the things you eat, how much you exercise, and take your medicines as prescribed, there may be times when your blood sugar levels climb above or fall below where you and your doctor want them to be. When this happens, it's called hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar).

It's important to recognize the telltale signs of hyperglycemia and hypoglycemia, what causes them, and what you can do to treat them. However, the first thing to remember is not to panic when you have blood sugar readings that are too high or too low, take action.

It's also important not to blame yourself for any out-of-range blood sugar levels. Sometimes it may not be easily explained. If you experience these blood sugar levels:

  • Redirect your energy away from anger, frustration, and self-blame
  • Plan ahead. Consider carrying your blood sugar meter with you so you can check your levels as often as your doctor recommends
  • Ask family, friends, and your healthcare team for help and support
  • Follow your doctor's instructions of what to do

Hyperglycemia

If your blood sugar level climbs too high, you may experience symptoms of hyperglycemia, which may include:

  • Increased hunger
  • Blurred vision
  • Increased thirst
  • Dry mouth
  • Fatigue
  • Weight loss
  • Dry, itchy skin
  • Frequent infections
  • Frequent urination
  • Slow-healing cuts or sores
  • Tingling/numbness in feet/hands

Hyperglycemia can be caused by simple things, like eating too much food, getting too little exercise, taking too much medicine, or an illness or stress. The only way to know for sure whether or not you have hyperglycemia is to check your blood sugar level.

How to Treat Hyperglycemia

Here are some things you can do when your blood sugar levels are too high:

  • Work with your doctor to adjust your meal plan or physical activity routine
  • Talk to your doctor about adjusting your medicines
  • Talk to your doctor about what a high blood sugar level is for you and when you should call

Hypoglycemia

If your blood sugar level gets too low, you may experience the symptoms of hypoglycemia, which can include:

  • Anxiety
  • Weakness
  • Confusion
  • Dizziness
  • Fatigue
  • Sleepiness
  • Hunger
  • Nervousness
  • Nightmares
  • Shakiness
  • Sweating

Hypoglycemia can result from too little food or exercise, too much medicine or alcohol. The only way to know for sure whether or not you have hypoglycemia is to check your blood sugar level.

How to Treat Hypoglycemia—The Rule of 15

If you feel low, check your blood sugar level. Is it in your target range? If you're low, follow the rule of 15.

  • Eat 15 grams of fast-acting carbohydrates, contained in foods such as:
    • Hard candies (not chocolate)
    • 4 oz (1/2 cup) of juice or regular (not diet) soda
    • 4 or 5 saltine crackers
  • Wait 15 minutes and check your blood sugar again
  • If your blood sugar is still too low, eat another 15 grams of carbs and check your blood glucose sugar level again after 15 minutes.

Hint: Lots of people overtreat themselves when they feel low because they treat the symptoms and not their blood sugar level. You may not feel better instantly after eating your 15 grams of carbs, but remember the rule of 15. You may want to keep eating until you feel better but that might make your blood sugar shoot way up. Be patient with your body and give it the full 15 minutes!

If you're still struggling to get within your target range, contact your healthcare professional.
