Cautions

  • Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed.
  • Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes contained in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.
  • Do not inject this medicine into skin that is damaged, tender, bruised, pitted, thickened, scaly, or has a scar or hard lump.
  • Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or diseases to pass from one person to another.
  • Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
  • You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).
  • Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.
  • Also, watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.
  • Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
  • Insulin is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
  • This medicine should look cloudy. Do not use the medicine if it looks clear or has particles in it. Call your pharmacist for new medicine.
  • Insulin can cause low blood sugar. Avoid driving or operating machinery until you know how this medicine will affect you.
  • Avoid medication errors by always checking the medicine label before injecting your insulin.
  • Avoid drinking alcohol. It can cause low blood sugar and may interfere with your diabetes treatment.

Pregnancy & Lactation

  • The limited available data on pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes; published studies during pregnancy have not reported an association between the drug and induction of major birth defects, miscarriage, or adverse maternal or fetal outcomes; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy
  • Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications; also increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity
  • Lactation
    • There are no data on the presence of the drug in human milk, effects on the breastfed infant, or milk production; one small published study reported exogenous insulin present in human milk; however, there is insufficient information to determine effects on the breastfed infant and no available information on the effects on milk production; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for insulin, any potential adverse effects on the breastfed child from the drug or underlying maternal condition.
